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.

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 $525 – 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 $550 – 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 $600 – 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: 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. (Not compatible with guide handle.)

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. Handle attaches to lower d-rings with spring snaps and angles back behind the metal support handle; 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.
    • Flexible Support Pull Handle (add $45)
    • Semi-Rigid Support Pull Handle (add $65)  Most popular!

Velcro stabilizers hold the handle in position (not easily removable). Available as a flexible handle, or semi-rigid which is reinforced for a sturdier feel. 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.

  1. JohnBFisher

    (verified owner) – Aug 22nd 2012:
    Sigh! Sometimes life hands us lemons… That’s when we need to grab our powered juicer and share lemonade with friends. Embrace life with the best possible tools we can find. As my neurological problems advance, I need more assistance. So, I started the long training process to teach my dog to be my Mobility Assistance Service Dog. And I started to look for the best tools available. I spent hours searching and found several users who were happy with Katrina’s Mobility Support Harness. Yes, it’s expensive. But this harness needs to last around 10 years. And my dexterity continues to decrease. It is important the harness be easy to use. I needed a design that made it simple to use even with my awkward hands. So, I ordered a Mobility Support Harness.
    Though I was hopeful, the quality of workmanship on the harness astounded me. The leather quality is exceptional. Though it is new, it’s not terribly stiff. However, it feels quite sturdy. The stitching is very even, tight and consistent. The handle support is rivited to the harness with FOUR rivits. Most manufacturers would think just two would do the job. The ability to easily swivel the handle down is a great design – and easy to use with the pull rings. The fit on my dog is exceptional. As recommended, I adjusted the straps to get the best fit. With those adjustments, it is very sturdy. It does not slip about.
    What’s more important is how the harness seems to transform us. The handle tends to transfer my intentions to my dog, who automatically reacts. I start to turn left and he senses it. I start to turn right and he senses that. And he tends to counteract my normal tendency to weave about it bit. It’s a normal reaction. Dog’s instinctively react against pressure. Lean into them and they lean back. Lean away and they lean away. As a result, my instability is stabilized. As another person with ataxia noted, having a service dog makes it feel as if you have a mobile handrail that goes with you.
    So, lemonade anyone? [ Thanks Katrina for this particular power juicer !! 8^) ]

  2. Megan & Saxton

    – Aug 3rd 2012:
    I’ve had my mobility harness for a year now and it’s by far the best thing I have ever used! I had a harness before this but it moved all over and it wasn’t even high enough to really be of any use. BLD Mobility harness is by far the best thing I have found on the market yet. Saxton loves to wear it and wears it with pride. It looks so professional and works so well. I don’t have to worry about it breaking and with the help with fitting it to Saxton perfectly its just so care free. Katrina has been so easy to work with and so helpful with the whole thing. Even when things go wrong she’s right there to help figure out a way to fix it. She has saved my life with this harness!
    And her leads are amazing as well, most leather leads are hard and bulky and her’s are just so easy to use!

  3. JD Richards and Blaze

    Jun 16th 2012:
    Blaze and I started out with the basic mobility harness and then when I needed to upgrade to the new harness, Blaze was able to adjust to the Mobility Support Harness. This harness is by far the most comfortable and easiest one to use. I can feel the support I need and I can see that Blaze isn’t under any strain at all when he’s working. He actually enjoys being in this new harness. Thanks Katrina for providing the upgrade in your usual timely manner! Even my Doc thinks I have found a “great source”. I love what you do. Thanks!

  4. Trina Brown

    Jun 16th 2012:
    Great harness, far superior to our previous harness. Excellent fit, Moses is much more comfortable now and literally sticks his head into the harness as soon as I pick it up! Fold down handle is a great feature, especially for restaurants-no more bumping into the bottom of the table. My only suggestion is to make the knobs on the outside a little more flush with the handle so they don’t get hung up on my trousers. Otherwise a wonderful product.

  5. Jim Wicker

    If you have found BLD your search is over. Hands down Katrina makes the best mobility harness on the market. Best quality& durability around ! I wanna thank you Katrina for opening up a whole new much less difficult world for me & Hershey both. Yes it says five stars but deserves much more.

  6. Helen P.

    I just got my MSH harness & cape and I absolutely love it!! The quality of workmanship is amazing and I have already gotten many compliments on how good it looks. I’ve also now purchased 4 8-way leashes with the oldest being about 3 yrs ago and it looks as good as the day I received it. I will never buy leashes from anyone but Katrina and Bold Lead Design.
