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. Our famous Lifetime Warranty, plus BLD’s excellent customer support, is standard with everything we make in our workshop.
Allow 4-6 weeks for your harness to be crafted to order.

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.

Need help with sizing? Don’t hesitate to ask! Contact us. We’ll take a look at your dog’s measurements to be sure you get the right size (before or after you place your order).
The below chart can help you determine the harness size you need. Weight and girth measurement are the most important.
(Don't worry about the other components, we will build the harness based on the dog's measurements)

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. Overtime the leather develops a unique and beautiful patina that becomes a darker as it ages.
Specialty and limited edition colors:
The main body and breastplate will be made in your chosen color. The handle, straps, and smaller parts will be black.

Handle Options
The MSH harness has 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.
The MSH can have a second handle made from leather to add more functionality to the harness. All are made to your desired height/length.
Leather Handle Options:
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.

Materials & Guarantees
As always, we stand behind the quality of our in-house handmade products with a Lifetime Warranty on materials and workmanship.
Please find complete warranty details here.
Did you know BLD products are designed to be repaired instead of replaced? Even if the item is not covered by our warranty (like for chewing), most damaged leashes can be repaired and made functional for a nominal fee.
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.
