Light Assistance Harness 2.0
$900.00
Unit price perProduct 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.
- 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.
- 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.

BLACK LATIGO leather
Latigo tanned specifically for quality horse tack and premium pet products and has a high tensile strength. Your leash will start out a bit firm yet flexible and will very quickly soften and will continue to get better with age. The rich black color is drum dyed during tanning (rather than just dyed on the surface). Made in North America from select US steer hides. Stainless steel (silver color) hardware is standard.
English Bridle Leather in LONDON TAN
English bridle has a supple, satin-smooth finish and satisfying hand feel that is simply unmatched. London Tan, cherished in the 19th century for the finest horse tack, ages to a warm patina while keeping its lighter brown and orange tones. This full grain leather is 100% veg tanned with no metals or harsh chemicals. Made in North America from select US steer hides. ("English" refers to the style of tanning rather than a location.)
Solid brass (gold colored) hardware is standard.
Caring for leather: Your BLD leather gear will last for many years and only get better with age. Leather is resilient, don’t be afraid to use it in daily life. A light coat of conditioner rubbed in like lotion keeps it healthy.
