BLD’s Mobility Support Harness (MSH)

Who is it for? The MSH can be a good option for people with balance impairment, disequilibrium, neurological conditions, or other conditions where light to moderate contact with a rigid vertical handle can assist with orientation and/or balance support. This harness can provide light bracing while the dog and the person are both standing. An additional leather handle can be added to allow the MSH to assist with momentum, gait stabilization, pulling, leading, and counterbalance support while in motion.

Custom made-to-order, this harness is handcrafted in our own workshop specifically to fit you and your dog. We offer a Great Fit Guarantee and a Lifetime Warranty on materials and craftsmanship. A complete Mobility Support Harness starts at $500. Most clients spend around $650 for a harness with additional options and accessories designed to meet their individual needs. The information on this page is summary of what we have to offer; for a printable, easy to read format, please download the Complete Information Booklet to discover all of the options and details available on this harness!

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, 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.

We proudly offer good old-fashioned customer service and excellent customer support before and after you place your order. Because proper fit is essential, we offer a Great Fit Guarantee on all made-to-order harnesses. Our famous Lifetime Warranty is standard with everything we make in our workshop.

Harness Size & Color:

  • Standard MSH $500 – 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 $525 – 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.) Available in black only.
  • Giant size MSH $585 – 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 in black with standard bars. No tall handles or pull-rings are available.
  • 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: (add $20) Gorgeous bridle leather. Tan shades may vary slightly; each part of harness may be a different shade but always coordinate beautifully. May darken and show some scuffs with use over time.

Choose Latch 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 (add $10) – D-rings placed near the quick-release make it easier to grasp the straps and fasten with one hand.
  • Magnetic Latches (add $40) – Ideal for those with very limited strength or dexterity! – This amazing latch, designed for motorcycle helmets, is reliable and secure. These self-align and hook closed when fastening the straps; incredibly easy to release by pulling the red tabs. Includes D-ring on strap for one-handed use.

Rigid Support Handle height and grip style:

  • 2-4”
  • 3-6”
  • 6.5-8.5”
  • 9-11” TALL* (add $35) Tall option includes heavier gauge metal and upgraded support bars on 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 tall handle is required.
    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. Handlebars can be replaced at any time with a similar height (Tall handles will ONLY fit on harnesses ordered with a TALL handlebar option).
  • Straight Grip: 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 (add $50):    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, ergonomic handle can be used with opposite hand; palm will face forward.)
Handle Folding: All Support Handles 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 (add $20)  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 nifty Infini-Key extenders for convenience.

MSH additional handle options: Customize your MSH harness for pulling, leading, forward momentum, and guiding; several handle styles to choose from.
  • NONE – When pulling or leading is not needed.

  • Support Pull Handle  Highly recommended!
    • 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.

Available as a flexible handle, or semi-rigid which is reinforced for a sturdier feel and enhanced feedback. Custom made to desired length.

Important Notes:  

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. Dogs MUST be in our recommended weight/measurement range for the harness to fit and function properly.

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, mobility impairment, or other disability that requires specialty service dog gear. 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.

    Hi Katrina
    I just wanted to take a moment & thank you for the EXCEPTIONAL harness & custom leads you made for me & Emmy. Not only are the gorgeous but she is very comfortable wearing it all day. I have had many people comment they have never seen anything like this & what an amazing thing for people who have mobility challenges. I have been in & out of the hospital with my Mom the past several months & literally no one had ever seen this before. The physical & occupational therapists asked lots of questions so hopefully more people like me can get out in the world again & “have a life”. Everyday I walk with Emmy & my harness I thank you from the bottom of my heart for the freedom & ability to go places without my cane or walker.I LOVE both the quick release collar and locking jaw snap on the leads. It makes it so easy to get on & off as well as change lead length from walking to resting.Again, so many things to be thankful for this year & finding you is at the top of my list.

    I’ve looked at every mobility harness made and this is the best quality harness there is on the market. The quality of the leather and metal is un questionable. The harness is comfortable for the dog and is easy for her to move around in. She took to the harness within a week and after we got the new belly strap, there haven’t been any troubles at all. The fit is excellent. I love this harness and recommend it to everyone that I run into that needs this type of equipment. I direct everyone that I can to Bold Lead Designs that I can for that has any type of need that Katrina supports. I LOVE working with her.

    I have had my mobility harness for a little over two months now. It is beautifully made and worth every penny. My dog is not professionally trained. We are working with a wonderful trainer and making progress. Even though my precious dog and I aren’t a perfect team yet, I am out of the house and enjoying this incredible adventure. Many thanks to Katrina for her help – the fit of the harness is perfect.
    Let me simply add that I needed to remove the padding on the breast strap because it seemed to hurt my dog’s front legs when he walked. Otherwise, the harness is wonderful.

    AMAZING HARNESS! The quality and craftsmanship of this harness is outstanding and it is clear that a lot of thought was put into the design. My dog also loves the harness and seems to find it very comfortable, he actually runs into it now when it is time to work! You cannot find a better harness out there and this one will last you forever. Katrina really is an artist and I wont put another product on my dog. I know with her products that it will not only be of excellent quality, but also be safe and comfortable for my dog.
