BLD’s Mobility Support Harness™ (MSH)
BLD’s world-famous 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 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! BLD’s innovative harness design has benefited thousands of people around the world since 2009.
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. Our famous Lifetime Warranty, plus BLD’s excellent customer support, is standard with everything we make in our workshop.
This harness provides vertical stability support and can be used for occasional light bracing, such as getting up from a seated position or for balance while standing (Dog should always be standing square to brace in these situations). Each MSH harness comes with a rigid metal support handle made from lightweight, high-grade aluminum. These handles are designed with a low center of gravity to distribute pressure around the dog’s core. Metal support bars are permanently mounted to the harness saddle and will not loosen over time. These support bars also feature support D-rings on each side which can be used for attaching other handle styles if needed.
Please note that the MSH is only for dogs over 60 pounds that are large and strong enough to perform this physically demanding work for their partner.

MSH Harness Size:
Standard MSH $530
For most dogs 60-95 pounds, with a girth size of 28-34 inches (best choice for most retrievers and doodles). NOT available for dogs under 60 pounds.
Extra Large MSH $555
For most dogs 90-150 pounds, with a girth size of 33-40 inches (also recommended for deep-chested breeds such as GSD’s and Dobermans weighing 85 pounds or more, and any dog over 100 pounds such as Rottweilers, Great Danes, Newfoundlands, etc.)
Giant size MSH $605
For dogs 140-200 pounds, with a girth over 40 inches (best choice for larger/male Great Danes, St. Bernards, Mastiffs, etc). Sorry, not all options are available on this size. ONLY available with standard bars. No tall handles or pull-rings are available.
- Black: Solid black latigo leather is our standard offering. Because the leather is solid black all the way through it does not fade, hides the appearance of scuffs, and wears beautifully over time.
- London Tan ($): 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.
Rigid Support Handle: Height and Grip Style
Each MSH comes with a rigid support handle made from lightweight, high-grade aluminum. Each handle has a padded handle grip that is comfortable and easy to clean and features reflective tape on the sides of the handlebar for night-time visibility.
The rigid support handle is available in the following heights:
- 9-11” TALL* ($) Tall option includes heavier gauge metal and upgraded support bars on the saddle.
*Tall handles apply more torque and pressure to the dog than shorter handles. Not recommended for most users or any dog smaller than stated minimum size. Consider the BAH if a tall handle is required.
*Tall handles will ONLY fit on harnesses ordered with a TALL handlebar option
NOTE: Height is the distance between the top of the harness saddle and the top of the handlebar. Support Handle adjustment range listed is approximate; exact dimensions depend on the harness size and dog’s width. Measurements will determine the handle size you need. Handles can be replaced at any time with a similar height (excludes Tall handles as they will ONLY fit on harnesses ordered with a TALL handlebar option).
Grip Options Available:
- Straight Grip: Default standard option
Standard handle grip is ambidextrous. Your hand and elbow will be positioned directly over the dog’s body, with your palm facing back.
- Ergonomic Grip ($): Highly recommended!
Z-shaped handle grip allows for more natural hand and arm position. Arm and elbow are able to relax in toward your body while your hand remains centered over the dog. Ergonomic grip is comfortable and balanced for most people, especially those with hand/wrist/shoulder mobility or pain issues. When necessary, an ergonomic handle can be used with the opposite hand; palm will face upward.
- Handle Folding:
All support handles are able to fold down!
- Standard release pegs:
Standard release pegs are a small metal knob (dime sized) that pulls out to release the handle so it can fold back. Can be operated together or independently when the built-in locking mechanism is engaged.
- Pull-Rings ($): Highly recommended for weak hands or one-hand operation
For people with limited dexterity who have trouble grasping a small peg, Pull-Rings can be added to make it easier to operate the handle folding mechanism. Includes Infini-Key extenders for convenience. (Not compatible with guide handle)
The MSH has optional additional handles so you can customize your MSH harness for pulling, leading, forward momentum, and guiding. There several handle styles to choose from:
- Basic Pull-Strap ($):
This simple leather strap is adjustable and forms a 3-6” handle when clipped onto the standard D-rings. Good for getting up from a seated position, or occasional wheelchair pulling. (Not built into the harness, can be added anytime.)
- Support Pull Handle ($): Highly recommended!
Available in Flexible or Semi-Rigid Leather (most popular!)
The Support Pull Handle is designed for heavier momentum and pulling needs and can be made to any length. This handle is best used as the primary handle for those who need moderate gait stabilization, a sturdy momentum pull, or leading of any kind. Handle attaches to lower d-rings with spring snaps and angles back behind the metal support handle; the harness will be made with “mouse ear” loops to provide optimal pulling pressure distribution. Available as a flexible handle, or semi-rigid which is reinforced for a sturdier feel and enhanced feedback. Custom made to desired length.
- Leather Guide Handle ($):
Available in Flexible or Semi-Rigid Leather (most popular!)
Leather guide handle allows for light-duty leading or momentum. Attaches to the front edge of the harness with quick-release buckles, and angles back behind metal support handle for proper leading or momentum contact. Velcro stabilizers hold the handle in position (not easily removable). Available as a flexible handle or a semi-rigid handle (the semi-rigid handle is reinforced for a sturdier feel). Custom made to desired length.
*Not compatible with pull-rings as the handle interferes with and can damage the pull-rings.
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.
- Extra set of bolts: Highly recommended! Removable bolts hold the handle onto the harness. Keep a spare bolt handy at all times, just in case (Your harness will come with a full set of bolts that include a pair of round caps and a pair of wing caps).
- Cape/Vest: Specifically designed to be compatible with your harness! 3 pockets and 3 Velcro panels to add patches (available separately). Only available with Quick-Release Buckle.

Leather care is easy! Don’t worry too much, and don’t be afraid to use your items — we promise leather is incredibly resilient, and regular weather won’t hurt it. If you think your item looks dirty, dry, or just need a little extra love, pouring a little leather conditioner on a cloth, and rubbing it in like lotion will usually do the trick. Baths and a jaunt in the river are just fine, but you might want to offer a little conditioner to your products afterwards. Saltwater can be harsh, so after a visit to the ocean, a good rinse in fresh water and proper conditioning will help preserve and protect your treasured leash or collar. See our Leather Care page for more specific information.
Luckily, the harnesses are easy to clean and maintain! Simply apply leather conditioner regularly to keep harness supple & weather resistant and clean the wool lining using a brush and vacuum.
Your harness can also be hand washed if needed. Here is a video on how to hand wash your harness:
Due to the custom nature of this special harness, returns and refunds are not available on this product.
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 is physically demanding; a service dog must be in prime physical condition. The dog’s growth plates must be closed before beginning harness work (recommended minimum of 18-24 months of age). Please allow your dog time to grow and mature.
Consulting a qualified veterinarian (orthopedic specialist or canine sports medicine physical therapist) is highly recommended for all service/assistance dogs that perform physical tasks. 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. Likewise, harness users should consult a physician and physical therapist to determine what medical equipment is appropriate for their mobility needs.
Our equipment is designed to allow an appropriately selected and trained service dog to reasonably assist a person with a balance or mobility impairment. BLD cannot assess a dog’s suitability or appropriateness. BLD harnesses are not intended to serve as, or to replace, a durable medical device such as a cane, walker, or crutch. User assumes all responsibility for the safety, health, and care of the animal and human alike.
The proper fit for each harness is assured by our Great Fit Guarantee. Our famous Lifetime Warranty, plus BLD’s excellent customer support, is standard with everything we make in our workshop.
