Description

The Light Assistance Harness (LAH) is a light-weight, low-impact, leather harness for close-contact communication between a service dog and their human partner. 

The LAH features a semi-rigid standing handle that offers proprioception support, counterbalance, light duty forward momentum pulling and leading (guiding) that can be used while standing or walking.

The LAH follows the natural contours of the dog’s anatomy and has minimal impact on the dog’s gait and movement when properly fitted. Engineered to allow full range of motion of the dog’s shoulder joints, this harness design minimizes the load at the front of the dog’s chest. Handle pressure is well distributed around the dog’s center of mass so the dog can offer support with minimal effort. All harnesses are custom-made to order!

Every harness is handmade to order in our own Colorado workshop. Finely crafted from only the best full grain leather and durable top-quality hardware to our exacting quality standards. Turnaround time is 4-6 weeks from date measurements and details are confirmed. 

As with all service dog harnesses we make, the custom-ordered LAH is backed by our famous Lifetime Warranty. Additionally, proper fit is assured by our Great Fit Guarantee (see details below).

Who is it for? 

The LAH is a good choice for many people with conditions such as vertigo, balance or gait impairment, disequilibrium, neurological conditions, brain injuries, MS, chronic fatigue, etc. where light to moderate contact with a sturdy semi-rigid handle can assist with proprioception/orientation, stabilization and/or balance support.

About the Handle:

As with all BLD's assistance harnesses, the LAH is specifically designed around the handle. The harness’ body is specially designed to align the handle at the center of the dog’s center of mass (or gravity) and position all the straps in the right place. This alignment allows the dog to perform more work with minimal effort, because their mass is creating a large portion of the counterbalance or pull force needed to provide momentum and stability. This means the muscles don’t have to work so hard, thus lowering the impact of working in a harness.

Adjustable:

The breast collar and girth straps are adjustable to fine tune the fit. This allows for plenty of adjustment range should the dog’s weight or coat thickness change.

Harness Construction:

Highly specialized layers of padding serve three important functions: to protect the dog’s spine, distribute pressure lower down the dog’s sides, and to keep all hardware away from the dog’s body. It is both extremely sturdy and completely flexible to conform to the dog’s body. It is lined with smooth garment leather to allow the harness to glide with the dog’s movement.

There are four components to the LAH. Each component comes in multiple sizes for a total custom fit. The size of each component will be made to fit your dog's size and proportions.

• Balance Handle (semi-rigid is standard)
• Harness Body
• U-shaped Breast Collar (adjustable)
• Wide Girth Plate with adjustable girth straps (adjustable)

Sizing and Measuring

The Light Assistance Harness comes in a range of sizes for dogs of all shapes and sizes over 40 pounds. 

Each of the LAH harness components will be made to fit your dog's measurements, and the handle will be made to your desired height.

Measuring instructions and submission form can be found here along with a video.

Instructions can also be found in the LAH Complete Information Booklet,

ABSOLUTE MINMUM SIZE REQUIREMENT: The LAH will NOT fit dogs that are smaller than 35 pound or that have a girth measurement less than 25 inches. 

Please know that we cannot proceed with a harness order until we have all of the necessary measurements and details. If you plan to call for assistance or to order, it’s best to have your dog’s measurements handy!

Harness Options

Quick release latches 

Quick release latches connect the girth straps to the belly plate, making the harness easy to put on and take off. The harness comes standard with our easy-to-use metal side release latches on BOTH sides of the harness. Magnetic latches are available for those with limited strength and dexterity.

Latches can be placed on both sides, or just one side of the harness:

One quick release latch allows the belly/girth to stay attached to the harness when taken off the dog. A square ring connects the girth strap to the off-side of the harness. To put the harness on the dog, it goes over their head and the belly plate connects with one simple latch.

Having quick release on BOTH sides means the belly/girth can quickly unclip from the harness, and is removed from the harness. You only need one latch to put the harness on the dog and can ignore the opposite side and leave connected. Both latches are required if your harness has the Sternum/Martingale strap between the front legs. In this case, the belly plate stays connected to the breast collar when taken off the dog. To put the harness on dog, it will first go over their head, then the belly/girth will pass between the dog’s front legs, and the straps will connect to the left and right sides of the harness.

Harness Top and Handle Brace Imprints: 

The strap on the harness top can be imprinted with your choice of “Service Dog” or “Assistance Dog.” Silver is standard. The horizontal brace strap on the handle can also be imprinted.

Handle Core: 

The handle is made from three layers, with leather on the outside and a reinforced core to add stiffness. Black is the standard core of the semi-rigid handle. Red and blue are available to add a pop of color. See examples in the photos. The imprints, if selected, can be made to match.

Harness Sides: 

The sides have a diagonal stripe that serve several functions; it stabilizes the handle and keeps it flush to the saddle, and keeps the sides smooth to prevent the harness rubbing on your legs as you walk, The stripe can be made in your choice of styles:

• Reflective for low-light visibility
• Velcro to attach a small patch (1" x 3")

Y-Harness Option: 

A sternal strap (or martingale) that goes between the dog’s front legs is also an available option. Some dogs (standard poodles, for example) do best with a strap that connects the breast collar to the girth plate. This additional strap can help keep the harness in position; it prevents the breast collar from riding up, and the belly plate from sliding back. It is designed to be removable, and can be added at a later time if needed.

Color

Harnesses are available in our standard black and London tan leather. Or further customize your harness with a specialty or limited edition color.

• Black: Solid black latigo leather is our standard offering.  Because the leather is solid black all the way through it does not fade, hides the appearance of scuffs, and wears beautifully over time.
• London Tan: Gorgeous vegetable-tanned bridle leather. Color and shades will vary; each part of the harness may be a different shade. Tan leather naturally appears rustic and may show scuffs and wear over time; color may darken with use over time as a patina develops. 
• Specialty leather in red, white and blue: A fine pigmented latigo leather with a firm, satin surface that is resistant to scuffs. Main body and breast collar will be made in the selected color. Handle, tabs, and other components are black.
• Limited edition colors may be available! While supplies last, we have some gorgeous colorfast bridle leather to make your harness even more bespoke. Main body and breast collar will be made in the selected color. Handle, tabs, and other components are black.

Main body and breast collar will be made in the selected color. Handle, tabs, and other small components are black.

Harness Accessories

Harness Accessories:

These small and simple accessories are designed to work with the LAH without interfering with function.

The LAH is an intentionally minimalist harness design that is not compatible with capes or pouches. Items other than these shown below, risk throwing the harness off balance or altering the pressure load on the dog.

Round Badges (Leash Wraps) 

Our “Leash Wraps” are nice ways to add badging to the LAH. These round badges are two separate patches that Velcro back-to-back so they can be wrapped around the handle brace, or the strap on top of the harness. Sold Separately.

Velcro Patch:

If you select the Velcro side stripes, the harness can accommodate 1 x 3 inch (2.5 x 7.6 cm) Velcro backed patches to identify working service dogs. Sized to fit the Velcro side stripes on the LAH. Made from woven damask material, the wording and graphics on our patches are clear and legible to communicate your dog’s working status to the public. Sold Separately.

Short Grab Handle: 

The LAH is created to be a simple  single handled harness. However, it can accommodate a small simple grab handle if required. For those who insist on having a second handle this smaller option is compatible when clipped to the O-rings on the harness body. 8” overall length, 5” of leather, makes about a 3″ handle. Sold Separately.

Personal Items:

The harness can accommodate a few personal items, such as an ID badge, tags, or a clip-on light. The photo shows an ID badge clipped to the handle O-ring and tucks behind the handle and reflective strap. ID tags or a small clip-on light are shown, too.

Important Notes

Important Notes: please read this before ordering

Due to the custom nature of this special harness, returns and refunds are not available on this product. Dogs must be of appropriate age, size, fitness, and soundness for the work you would like them to perform. Dogs must be physically mature before training or performing high impact work in harness. High impact work includes pulling, guiding, counterbalance, and bracing. Harness work is not recommended until after growth plates are fused and joints and muscular system is fully developed, and a minimum age of 18 months. Consult a qualified veterinarian to assure your dog’s readiness and suitability harness work. Safety considerations: Mobility, stability, and balance assistance work are physically demanding; users assume all responsibility for the safety, health, and care of the animal and human alike. This harness is NOT to be used as a restraint or to control the animal, as a seat belt or safety restraint harness. Always supervise your dog while using this equipment. Do not leave a dog unattended with any harness. Not designed as or recommended for heavy or full-time wheelchair pulling, as this is a challenging asymmetrical task for a dog to perform. Please read and understand the harness owner's manual before use. BLD's harnesses are not for puppies or adolescent dogs. The adjustment range is limited and may not be able to accommodate a pup's rapid growth. It will cost you significantly more money if the dog outgrows the harness.  Use only with handles & accessories designed and approved by BLD for this equipment.

At Bold Lead Designs, we take the health and safety of your dog seriously. We have created these guidelines based on over 15 years of experience with this specialized equipment.  Our equipment is designed to allow an appropriately selected and trained service dog to reasonably assist a person with a balance, mobility impairment, or other disability that requires specialty service dog gear. BLD cannot and does not assess dogs' temperament, health or suitability to be a service dog. Fit and performance of the equipment can only be assured if the dog meets the minimum recommended guidelines, the user and trainer have reasonable expectations, and when the equipment is used responsibly for the purpose it was designed. 

Age, Size and Fitness:

• Dogs should be at least 18 months of age before training or working in a harness. The dog’s growth plates must be closed AND have a fully developed musculoskeletal system before training or working in harness. This is NOT the same as "full grown" which can happen months before a dog is physically mature.
• Full physical maturity happens for most large breed dogs at 18-24 months of age, with and giant breeds need even longer to mature. Please allow your dog time to grow and mature as rushing into harness work may cause injury and shorten your dog’s working life. Additionally, if the harness is ordered too soon it will cost you significantly more money if your dog outgrows the harness.
• Dogs MUST meet the minimum weight/measurement range set forth in the sizing guide for the harness to fit and function properly.
• Service dogs should be well-exercised, physically fit, and in good body condition (lean and muscular) throughout their working life. Consider implementing an exercise and fitness routine when the dog is “off duty” to keep him/her in good shape.
• Overweight dogs should never be expected to perform load bearing tasks; additionally, obesity contributes to serious health risks and can significantly shorten a dog’s lifespan by two years. 

Consult the Pros: We strongly advise all service/assistance dogs be examined by a qualified veterinarian (orthopedic/rehab specialist and/or canine sports medicine physical therapist) to determine if the dog is suitable for the demands of service dog work.

1. Radiographs (x-rays) of hips, elbows, and/or other tests are recommended to rule out dysplasia or other health conditions that may limit the dog’s ability to perform physical assistance. We recommend x-rays be evaluated by a radiologist, or reviewed and certified by OFA or PennHIP.
2. Understand that general practice veterinarians may not have experience with working dogs and the nuanced conditions specific to mobility dogs; for this reason a specialist is recommended whenever possible.

Likewise, harness users should consult a physician, occupational therapist and/or physical therapist to determine what medical equipment is appropriate for their disability and mobility needs. BLD harnesses are not intended to serve as, or to replace, a durable medical device such as a cane, walker, or crutch. Please understand that one should never lean on a dog to stay upright. Users should read, understand, and follow all instructions and information provided in the harness information and owner's manual before using the equipment. Improper use could put the dog and human at risk for injury. Additional Resources: To learn more about mobility dogs that provide balance and stability assistance, see recommendations developed by experts in the industry, and find links to research and other information, check out Mobility Dog Resource Group at mobilitydogresources.com.

In your dog’s best interest, please understand that BLD may decline or cancel an order if we believe a harness could be harmful to the dog because of age, size, or unreasonable expectations.

The BLD Balance Assistance Harness (BAH):

This is not your average service dog harness!

BLD’s specialty service dog harness is designed to provide balance and stability support for people with balance or mobility impairments, as well as for anyone needing good communication and contact with their service dog. We have designed this harness with the dog’s physical structure and movement in mind, and then added features to make it user-friendly and truly accessible. This is the most stable, ergonomic, and functional service dog harness available!

The Balance Assistance Harness can

• assist balance by counterbalance or pulling
• offers stabilization while standing or walking
• help maintain a regular gait
• provide forward momentum pulling, leading/guiding
• assist with getting up from a seated position

Guided by a veterinary orthopedic surgeon, canine sports medicine experts, and canine physical therapists, BLD’s unique harness design allows the dog to move, breathe, and work with minimal impact from the equipment. Weight and pressure are properly distributed across the dog’s body for optimal performance of physical assistance tasks. Similar to a horse saddle, this harness sits just behind the withers (or shoulders), around the dog’s center of gravity. When fitted properly, this harness does not wobble, shift, pinch, or rub the dog. It is lightweight, sturdy, and very comfortable.

Every harness is custom made by hand in our own Colorado workshop. Crafting each harness to order is how we are able to provide the right fit for the dog while meeting the user’s individual needs.

Proper fit is assured by our Great Fit Guarantee.

Designed to last for decades

This harness has been designed with interchangeable straps for the greatest flexibility; perfect for adapting a harness to fit a new dog or user. You may order replacement parts any time you need them. Support handles are replaceable if the harness is built to accommodate the height you need. In fact, we regularly help customers re-fit harnesses onto 3rd and 4th successor dogs (when the dogs fit the same size saddle). See replacement parts here.

NOTE: This harness does NOT offer bracing; leather assistance handle is lower impact and generally safer for the dog than a rigid metal handle. For bracing needs, see our Mobility Support Harness.

Sizing

BAH Harness size: 

Balance Handle (vertical) - most popular in semi-rigid style

The Balance Handle is positioned vertically on the harness. It is stabilized to provide excellent feedback and communication with your dog for counterbalance, stability and proprioception while walking or standing. Mounts low on the harness saddle with quick-release buckles, and is kept upright with heavy-duty O-rings. Folds flat by unclipping the quick-release buckles and pivoting back.

Available flexible or semi-rigid for increased sturdiness and feedback. Flexible handles soften over time and slump when not in use. Semi-Rigid handles are designed to hold their form and stand upright, making it accessible for grasping without bending over. (Not a brace handle–it will flex with direct pressure to diffuse movement and minimize torque on the dog.) You may also choose a handle core color for semi-rigid handles to add a pop of fun contrast!

Clip-on handle 

Minimal, low profile option clips onto heavy-duty d-rings toward the top of the harness saddle. Makes a good second handle for occasional tasks like getting up from a seated position, or for occasional momentum assistance. Can be made to any length/height. Also available as a Short Grab Handle sized so it’s just enough to get ahold of for the shortest handle possible (about 2.5 inches)

Support Pull Handle - Most popular as a second handle in the semi-rigid style!

The Support Pull Handle is designed for heavier momentum and pulling needs. Provides optimal pulling pressure distribution. Handle attaches to d-rings with spring snap clips. “Mouse ear” loops keep the handle in position at a slight angle back. This handle drops a bit when you let go of it, and has a looser feel than the Balance Handle but is best for those who need moderate gait stabilization, a sturdy momentum pull, and guiding/leading. Available flexible or semi-rigid for increased sturdiness and feedback. You may also choose a handle core color for semi-rigid handles to add a pop of fun contrast!

Example of imprinted brace straps and semi-rigid handles with color cores:

Also available: Leather Guide Handle

Contact us if you'd like to order one. This is an older handle style and is not typically recommended. The Support Pull handle is the best choice for most people, as it is sturdier and offers more support and directional feedback than the Leather Guide handle.

More Customization

The BAH is made with easy to use quick release latches on one side of the harness, and adjustment buckles on the other side. To put the harness on your dog, you only need to use two latches! 

Choose Latch Option for Girth and Belly Straps:

• Quick-Release Buckles (Default standard option): All metal buckles are easy to operate. Spring-loaded side release style requires little pressure to open.
• One-Hand latch operation ($): D-rings placed near the quick-release make it easier to grasp the straps and fasten with one hand.
• Magnetic Latches ($): These special latches are easy to use and are secure. Ideal for those with very limited strength and dexterity and allows for one-handed operation. The magnets self-align and hook closed when fastening the straps and easily release by pulling the red tabs. These latches include D-rings for easy grasp when fastening the straps on your dog.

Important Notes

Important Notes: please read this before ordering

Due to the custom nature of this special harness, returns and refunds are not available on this product.

At Bold Lead Designs, we take the health and safety of your dog seriously. We have created these guidelines based on over 15 years of experience with this specialized equipment. 

Dogs must be physically mature and of appropriate size, fitness and soundness for the work you would like them to perform. Mobility, stability, and balance assistance work are physically demanding. A service dog should always be in prime physical condition to remain healthy.

Age, Size and Fitness:

Dogs should be at least 18 months of age before beginning harness work. The dog’s growth plates must be closed before starting to train a dog for harness work. This happens for most large breed dogs at 18-24 months of age and giant breeds need even longer to mature. Please allow your dog time to grow and mature as rushing into harness work may cause injury and shorten your dog’s working life. Additionally, if the harness is ordered too soon it will cost you significantly more money if your dog outgrows the harness.
Dogs MUST be in our recommended weight/measurement range set forth in the sizing guide for the harness to fit and function properly.
We want to see properly exercised, fit, lean, muscular dogs! Overweight dogs should never be expected to perform load bearing tasks; additionally, obesity contributes to serious health risks and can significantly shorten a dog’s lifespan. Consider implementing an exercise and fitness routine when the dog is “off duty” to keep him/her in good shape.

Consult the Pros:

Consulting a qualified veterinarian (orthopedic specialist or canine sports medicine physical therapist) is highly recommended for all service/assistance dogs that perform physical tasks. Radiographs (x-rays) or other tests may be recommended by the vet and are required by most service dog training organizations to determine if the dog is suitable for the demands of service dog work.
Harness users should consult a physician and physical therapist to determine what medical equipment is appropriate for their mobility needs. BLD harnesses are not intended to serve as, or to replace, a durable medical device such as a cane, walker, or crutch. Please understand that one should never lean on a dog to stay upright. Rigid metal handles must not be pushed or pulled on while the dog is in motion. Such use is not how the harness is intended to be used and could put the dog at risk for injury.

———————————

Fit and performance of the equipment can only be assured if the dog meets the minimum recommended standards, the user and trainer have reasonable expectations, and when the equipment is used responsibly for the purpose it was designed.
Our equipment is designed to allow an appropriately selected and trained service dog to reasonably assist a person with a balance, mobility impairment, or other disability that requires specialty service dog gear. BLD cannot assess a dog’s suitability or appropriateness. Users assume all responsibility for the safety, health, and care of the animal and human alike.

In your dog’s best interest, please understand that BLD may decline an order if we believe a harness could be harmful to the dog because of age, size, or unreasonable expectations.

BLD’s Mobility Support Harness™ (MSH)

This is not your average service dog harness!

BLD’s world-famous service dog harness is designed to provide balance and stability support for people with balance or mobility impairments. We have designed these harnesses with the dog’s physical structure and movement in mind and then added features to make it user-friendly and truly accessible. This is the most stable, ergonomic and functional service dog harness available! 

The Mobility Support Harness can

• • assist with balance and stability support while standing or walking
  • help maintain a regular gait
  • assist with getting up from a seated position.  
  • can be used for occasional light bracing (while the dog is standing)
  • accommodate a leather handle to add more functionality such as pulling
  • when a Support Pull Handle is added, provide counterbalance, momentum pull, and leading/guiding 

Guided by canine sports medicine experts, canine physical therapists, and a veterinary orthopedic surgeon, BLD’s unique harness design allows the dog to move, breathe, and work with minimal impact from the equipment. Weight and pressure are properly distributed across the dog’s body for optimal performance of physical assistance tasks. Similar to a horse saddle, this harness sits just behind the withers (or shoulders), around the dog’s center of gravity. When fit properly, it does not wobble, shift, pinch or rub the dog. It is lightweight, sturdy, and very comfortable.

Every harness is custom made by hand in our own Colorado workshop. Crafting each harness to order is how we provide the right fit for the dog while meeting each user’s individual needs.

Proper fit is assured by our Great Fit Guarantee. 

NOTE: as of 7/18/2026 we cannot guarantee a turnaround time. We are working through a massive rush of orders with limited staffing and are waiting on specialty components to be delivered. Orders will be completed as soon as we are able, timeframe may be as late as September, 2026. Thank you for your understanding.

Harness Features

Harness Features

• Harnesses are custom made to fit your dog’s measurements and conform to your dog’s anatomy

• All straps have several inches of adjustment to fine-tune the fit
• Rigid metal support handles can be folded down to allow dogs into tight spaces, into vehicles, and under tables/chairs
• Saddle is made with special padding to offload pressure from the dog's back and prevent strain on the spine
• Sheepskin lining on saddle, breastplate, girth, and belly straps provide proper cushion to prevent pinching or rubbing, as well as optimal structural support for the function of the harness
• D-rings for attaching accessories, such as a cape, pouch, ID badges, pulling strap, etc.
• The MSH is for dogs over 60 pounds (27 kg) that are large and strong enough to perform this physically demanding work for their partner

Designed to last for decades

This harness has been designed with interchangeable straps for the greatest flexibility; perfect for adapting a harness to fit a new dog or user. You may order replacement parts any time you need them. Support handles are replaceable if the harness is built to accommodate the height you need. In fact, we regularly help customers re-fit harnesses onto 3rd and 4th successor dogs (when the dogs fit the same size saddle). See replacement parts here.

Sizing

MSH Harness Size: 

ABSOLUTE MINMUM SIZE REQUIREMENT: This harness will NOT fit dogs that are smaller than the minimum recommended 45 pounds, 21inches tall, or with a girth size less than 28 inches.

Leather Color

Standard Colors:

• Black: Solid black latigo leather is our standard offering.  Because the leather is solid black all the way through it does not fade, hides the appearance of scuffs, and wears beautifully over time.

• London Tan: Gorgeous vegetable-tanned bridle leather. Color and shades will vary; each part of the harness may be a different shade. Tan leather naturally appears rustic and may show scuffs and wear. Over time the leather develops a unique and beautiful patina that becomes a darker as it ages.

Specialty and limited edition colors:

• Specialty leather in red, white and blue: A fine pigmented latigo leather with a firm, satin surface that is resistant to scuffs. Main body and breast collar will be made in the selected color. Handle, tabs, and other components are black.
• Limited edition colors may be available! While supplies last, we have some gorgeous colorfast bridle leather to make your harness even more bespoke. Main body and breast collar will be made in the selected color. Handle, tabs, and other components are black.

The main body and breastplate will be made in your chosen color. The handle, straps, and smaller parts will be black. 

Clip-on handle: Minimal, low profile option clips onto heavy-duty d-rings toward the top of the harness saddle. Makes a good second handle for occasional tasks like getting up from a seated position, or for occasional momentum assistance. Can be made to any length/height. Available as a Short Grab Handle sized so it’s just enough to get ahold of for the shortest handle possible (about 2.5 inches)

Support Pull Handle - highly recommended!  Designed for heavier momentum and pulling needs. Provides optimal pulling pressure distribution. Handle attaches to d-rings with spring snap clips. “Mouse ear” loops keep the handle in position at a slight angle back. This handle drops a bit when you let go of it, has a looser feel than A or B, but is best for those who need moderate gait stabilization, a sturdy momentum pull, and guiding/leading. - Most popular as a second handle in the semi-rigid style!

All leather handles that are 4.5" or higher will have a horizontal brace strap to stabilize the U-shape. These can be imprinted with "ASSISTANCE DOG" OR "SERVICE DOG" if desired.

 Example of imprinted brace straps and semi-rigid handles with color cores:

Also available: Leather Guide Handle

Contact us if you'd like to order one. This is an older handle style and is not typically recommended. The Support Pull handle is the best choice for most people, as it is sturdier and offers more support and directional feedback than the Leather Guide handle.

More Customization 

The BAH is made with easy to use quick release latches on one side of the harness, and adjustment buckles on the other side. To put the harness on your dog, you only need to use two latches!

Choose Latch Option for Girth and Belly Straps:

• Quick-Release Buckles (Default standard option): All metal buckles are easy to operate. Spring-loaded side release style requires little pressure to open.
• One-Hand latch operation ($): D-rings placed near the quick-release make it easier to grasp the straps and fasten with one hand.
• Magnetic Latches ($): These special latches are easy to use and are secure. Ideal for those with very limited strength and dexterity and allows for one-handed operation. The magnets self-align and hook closed when fastening the straps and easily release by pulling the red tabs. These latches include D-rings for easy grasp when fastening the straps on your dog.

Do you struggle to keep your dog’s leash from getting tangled in your wheelchair? Is holding the leash difficult, or not even an option? BLD’s Wheelchair Leashes and specially designed attachments might be the answer you have been looking for.

The Quick-Release Wheelchair Leash System is a short, single-length leash that can quickly be attached or detached from a wheelchair. The leash clicks on and off of your wheelchair with an easy to use quick-release buckle or special shackle snap. Add the optional handle, and it can be used as an ordinary leash. A belt loop is also available for those that wish to attach the leash to their belt.

The QR Wheelchair Leash System is modular so you can combine the parts to meet your needs. Parts include:

1. Detachable Leash
2. Chair Attachment
3. Optional separate Handle and/or Belt Loop

Info about our leather and width/size can be found below

Detachable Leash:

One end of the Detachable Leash has a regular leash snap to attach to the dog’s collar or harness. The other end is made to connect to the chair attachment you choose. 

The leash can be made in your choice of material, color, width, and length.

The secret to a safe Wheelchair Leash is selecting the right length! Please measure for the length you’ll need. The listed leash length is the overall size of the leash when attached to the wheelchair, which includes the chair attachment. It is adjustable by several inches and can be fine-tuned once attached to the wheelchair and the dog (Initial adjustment may require a helper).

All hardware comes standard in stainless steel/chrome (silver finish). *Not all components are available in brass/gold color.

Part #2: Wheelchair Attachment

Wheelchair Attachment:

The WHEELCHAIR ATTACHMENT mounts to the wheelchair. Easy to install on any part of the chair’s frame, tubing or armrest with a simple yet sturdy Velcro wrap. Chair attachments include a swivel to prevent tangling and can be made in either of the two styles, explained below. Chrome/silver hardware is standard.

• Standard Quick-Release buckle (standard QR) is a metal side-release buckle – just pinch the sides of the buckle to release. The male end of the buckle is on the chair attachment. Brass/gold hardware is available by request. *Note: swivel is only available in silver.
• Shackle Snap ($) is a sturdy and secure panic snap that releases instantly by pulling the tab, even under load. The stainless steel shackle is on the chair attachment. The leash will be made with an O-ring to clip into the shackle. The Shackle option requires more dexterity to attach the leash than the standard option, however, it releases in an instant by a hard tug on the release tab. Many clients choose this option if an assistant helps with leashing up the dog.

Part #3: Handle and/or Belt Loop

Optional Separate Handle and/or Belt Loop: 

• 12” Traffic Lead Handle ($): To use as an ordinary leash when detached from the wheelchair, simply add a 12” Traffic Lead Handle. The handle is a simple loop with a leash snap that clips onto the ring included at the end of the detachable leash. The Traffic Lead Handle will be made to match the color and width of the leash.
• Belt Loop Attachment ($): If you wish to be able to wear the leash hands-free while standing or walking, the Belt Loop allows you to connect the leash to your belt.

How to install a Quick Release Wheelchair Lead

(standard side release buckle shown)

Measuring

Measuring instructions for Quick-Release WC Leash:

1. Determine where you want the leash to attach to the wheelchair. Choose a location that is within reach of the user and that is structurally sound so as not to damage or interfere with any part of the mobility device.
2. Attach an ordinary old leash on the dog’s collar or harness.
3. Hold the leash or loosely wrap the leash around the determined attachment point on the wheelchair, at a length that is comfortable for the dog to stand, walk, and sit next to the wheelchair.
4. Be sure the leash is short enough to prevent the lead from becoming trapped in the wheels and/or motor, yet long enough for the dog to comfortably get behind or in front of the chair to go through a doorway and common tasks.
5. Measure the old leash from the attachment point on the wheelchair to the dog’s collar or harness.
6. Select the leash length that best fits your measurement. If borderline, select the larger size.

Material & Hardware Options

Hardware:

We use only the highest quality hardware—most of our hardware is stainless steel or solid brass for durability and longevity. Stainless steel bolt snaps and premium metal hardware are standard on all of our wheelchair leashes. 

Other leash snaps or a built-in collar are available by special request.

Premium Leather:

Our leathers are incredibly durable, yet flexible. We use thinner leather for these leashes to keep them lightweight. Choose from two widths:

• Regular half-inch wide (12.7 mm) is recommended for most dogs and people as it’s sturdy for any size dog, yet not too heavy.
• If you like a wider, heavier leash and larger hardware, select the wider 5/8″ (or 3/4″ option in Brahma).

Brahma Soft-Grip—a vegan leather alternative:

Brahma Soft-Grip is constructed with webbing on the inside and a durable, non-tacky PVC coating on the outside. Easy to care for: just wipe clean with soap and water. Assembled with screw posts for durability. This material is heavier than leather (in a comparable width), and does not soften over time the way leather does. Black is the most popular color for wheelchair leashes, but assorted bright and classic colors are also available. 

• Regular half-inch wide (12.7 mm) is recommended for most dogs and people as it’s sturdy for any size dog. Brahma is heavier than leather.
• If you like a wider, heavier leash and larger hardware, select the wider 3/4″ option in Brahma.

Available Brahma Colors:

• BLACK- most popular
• COBALT BLUE
• BRIGHT MINT GREEN
• BRIGHT PINK
• HUNTER ORANGE (high visibility)
• PURPLE
• TEAL

Regular half-inch wide (12.7 mm) is recommended for most dogs and people as it’s sturdy for any size dog, yet not too heavy.

If you like a wider, heavier leash and larger hardware, select the wider 5/8″ (or 3/4″ option in Brahma).

These products are intended for use with fully trained service dogs/assistance dogs/pet dogs that have excellent leash manners. We’ve designed all of our Wheelchair Leash options to manually detach from the wheelchair in the event of an emergency situation.

Only you can determine if letting go of the leash and attaching it to your wheelchair is the right choice for you and your dog. Please choose your equipment wisely and use responsibly.

Attached leashes (fastened to a person, wheelchair, or another mobility device) are not safe for all dogs and/or users of wheelchair/mobility devices. 

Do not use wheelchair leashes with an untrained dog. Not for dogs that pull on the leash. Wheelchair leashes must NOT be used with dogs that lunge or are difficult to control, as this could be very dangerous. Additionally, DO NOT USE FOR PULLING A WHEELCHAIR.

Please note: If your strength or dexterity is limited, you may need assistance from a friend to install the wheelchair attachment and make the initial adjustment to the leash. Once attached and adjusted, the leash will remain at the desired length and is easy to connect to and remove from the wheelchair. The attachment stays on the wheelchair when the leash is not in use.

A simple, short, clip-on handle 

We’ve created this little clip-on handle for those that would like a simple grab handle added to the BAH, MSH, or LAH.

Most commonly used for pulling up from a seated position, or for occasional wheelchair pulling. 8″ overall length, with 5″ of triple-layered leather, creates approximately a 2-3″ handle.

(Will not fit BLD’s everyday working harness, the clips are too small for the D-rings.)

Made from layered, 5/8″ wide leather and stainless steel snaps just like BLD’s other leather harness handles. This grab handle can be used anytime you need the dog to pull with a quick tug, such as for climbing stairs, getting up from a seated position, and even pulling a wheelchair on occasion.

Stainless steel snaps are on each end and clip to the accessory D-rings on the BAH and MSH, or onto the top O-rings on the BAH and LAH.

Designed to fit only the indicated harnesses by Bold Lead Designs. Accessory strap only. Harness not included.

Martingales are among the safest collars to use with a leash because there is no choking and dog's can't slip the collar. 

These beautiful leather collars are made from the finest leather and highest quality stainless steel chain. Edges of the leather are beveled for a smooth edge for comfort and to protect your dog’s coat.

• Adjustable leather collar for walks and training
• Prevents dogs from slipping out of the collar
• Rust-free solid stainless steel chain
• Many sizes and widths to fit nearly any dog
  
• Artisan handcrafted in Colorado, USA!

Sometimes called a half-check or limited-slip collar, it's designed to fit loosely, then partially tighten enough with leash pressure so the dog cannot back out of the collar. It's a great choice for small nervous dogs as well as large powerful dogs. 

We've re-designed our popular Martingale Collar with a wider selection of neck sizes and widths from 5/8 inch wide for small dogs, and up to 1 1/2 inch wide for large breeds. 

Info about our leather can be found below.

NOTE: Martingales are intended to be used with a leash; not recommended for full-time wear or when the dog is unsupervised for concern the chain could get caught on an object and trap the dog.

Styles

Select from two styles:

• Plain - sleek design has minimal hardware and slips over the dog's head; Conway adjustment buckle is smooth on the inside and won’t irritate your dog. The collar stays adjusted to the dog's neck size, plus, there's no excess "tail" to flap about.
• Buckle-style - has a regular buckle for adjustment; it can be buckled around the neck, or slipped over the dog's head. 

FAQS

Frequently asked questions about BLD Martingale Collars: 

Do you offer a clip-on style? For safety concerns, we no longer offer the clip-on style. 

Can you add a quick release type buckle? No, sorry. Quick release type buckles are not available because the hardware required to make them takes up more than half of the dog's neck size.

Can I change the hardware to brass or gold color? No, sorry. We've discontinued the brass chains because the oxidation can stain dog's fur.

I'm not sure what width is best for my dog. What do you recommend? If your dog has a lighter frame, or is sensitive to gear, choose the narrower option. If your dog is burley and thick, like bull dogs and bully breeds, the wider option would be great. 

My dog's neck is in between sizes. What size should I order? Our collars are designed with a little extra room than the stated size range. If your dog is young and in-between sizes, size up to allow a little room should your dog fill out or gain weight. A larger collar can always be adjusted smaller.
