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 $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.
  • Basic Pull-Strap (add $25) 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!
    • 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.

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.

52 reviews for Mobility Support Harness™ for brace and balance stability assistance

  1. Brent R

    Thanks so much, this harness is a godsend. After trying other manufactures an it taking me up to 45 minutes to put the on, I can truly appreciate the Bold Lead harness. I can put it on Jack in no more than 2 minutes, on a bad day. It is as or more or as stable than other manufacturers and definitely a far superior quality. As with anything in life, we all have something that we would add that is just for us individually. For me, I would like to see a small leather strap that would clip between the pins to lower the handle, it would just make it easier for a one handed person to raise and lower.. With that said, I couldn’t be happier to have spent the money on a mobility harness from Bold Lead Designs. Even now with the budget I must be on, it was so worth the sacrifices!

    Thanks again,

    Have had my harness for 3 months now, and I love it. The craftsmanship is excellent, and after having worn it a few times Shep quickly got used to it, enough to take naps in it when he needs to rest. When I first got it the handle was not quite long enough (which was my fault, I measured without using my cane as I was standing) but BLD quickly took care of the issue, sending me a new handle as I shipped the original handle to them. The harness works well for me; I use a cane for support but had issues with balance, and often would stagger a bit when walking. With Shep and the harness, I no longer have balance issues, I keep my fingers on the harness handle and it keeps me anchored in space. Richard

    TESTIMONIAL FROM DAVID NOWAK, M.Sc., Service Dog Instructor Trainer, Director of Kayla’s Paws Service Dog Training, Education & Assistance Foundation a approved 501(c)3 Nonprofit Organization


    September 15. 2015

    Over the last several years I have been working with, the owner Katrina, and have watch them grow from a small one person operation into a now huge work facility. They are dedicated crafter and, in my experience and in my opinion, Bold Lead Designs are experts. The majority of their work is custom made service dog harnesses, but they have a variety of interesting and intelligent other service dogs, reqular workin gear, as well as, leashes, collars, toys, and other specialty items. All their items are hand made with exeptional quality in both design and functionality. BLD stands by all their products and provides excellent customer service!

    In example service and other working dog harnesses are custom made for each dog, this provides them and the handler comfort and safety. They offer various designs, and each can be customized to what the clients needs are…THESE ARE NOT MASS PRODUCED OFF THE SHELF PRODUCTS. The old saying that you get what you pay for means exactly that with BLD, Katrina, and her staff. I have never had a problem with fitting any of my service dogs or in training service dogs with a BLD harness….because they are just that good, and when properly mantained they last and look the same way they did out of the box. Katrina backs up the BLD with a garantee.

    My first harness I bought from Katrina, looks the same way as the first day it arrived over 8 years ago and my dog SD/SAR Kayla would tell you it excellent. When the harness comes off the wall, she gets excited to this day and goes directly into “business mode”….

    I have alot of BLD designed products, leashes, collars, etc. they have all are excellent and some are very unique items only BLD makes. But requardless of what is made, I don’t even have to question that I would give a 10 star rating if I could, but since the highest rating is normally 5, I will give all their products a 10 regarless. I highly recommend Bold Lead Designs, with out question….you need a harness, BLD should be your first choice. Typically since the harnesses are custom made for your dog, this does take some time to build them to your dogs measurement, but its worth every penny and worth the waite to get the harness. So if you are thinking of purchasing a harness for your service dog, I highly recommend Katrina and Bold Lead Designs..!

    If you have a problem with any of the products that you purchase from BLD, the provide excellent customer service, they are polite, efficent, and solve the problem quickly.

    As they function on quality rather than quantily, they are experts, and all tallented harness makers, and makers of other fine equipment! You cant go wrong with the best equipment available!

    so check out their website and testimonials, when you purchase someting tell them that you Kayla’s Paws sent you! (that is a unsolicited tetimonial)

    If it were possible to give more stars I would. I had been researching over 6 months for something that would make working with my guide dog safer due to my neurological challenges. The guide dog school I graduated from sent trainers to my home to assist us with balance trainging. Even with the modifications I was still unstable on my feet at times. I would cancel appointments and social engagements chosing to stay home beacause I was afraid of tripping and falling.

    I emailed and called Katrina relaying my challenges and questions. Katrina took the time to personally speak with me and answer all my questions. She also worked with my guide dog school educating them about the harness with guide handles abillities. The guide dog school was cautious but interested in looking further. Katrina graciously sent a demo harness with guide handle to the school to test out. Of course they were just as happy as everyone else who uses thie BLD harness and guide handle.

    Now I am the proud owner and user of a BLD mobility support harness with guide handle and couldn’t be happier. I am confident that I no longer need to cancel appointments.

    My guide adjusted to the new harness easily. I had originally been concerned with the transition to a different harness but I had worried for nothing. I had created a tarining schedule once I ordered the harness. My goal was to have us ready in a month to transition to the BLD harness full time in a month. Well, we didn’t make our goal we surpassed it. After introducing the new harness we haven’t touched his orginal harness. We exclusively guide with the BLD mobility support harness with guide handle.

    This product is of exceptional quality, made to order, with the best customer service imaginable. Don’t hesitate to inquire about the products. This has been one of the best purchases I have ever made.


  6. Sarah W in Austrailia (verified owner)

    Without any dout all the items that i have bought from BLD have been fabulous, and my service dog loves them, our first item we bought was the lead, having not long been teamed up with my service dog at the time i wanted him to have a real leather lead like his buddy’s that were guide dogs , i searched and searched but could not find one in my town, so i went on line and BLD popped up , there prices were great , i bought the lead and a few weeks later it arrived , the next item i bought was the MSH as my balance had been getting worse over the years, this one was a item i gave much thought to after looking in to it extensively i found it would be safe and beautiful for my service dog , i love how it gives the illution of being big and heavy but in reallity it’s super light, yes the rib cage strap that was sent with it was to big but after a quick chat with the BLD staff, a smaller one was sent free of charge and i sent the large one i’m guessing was an XL back to them no issue, when the harness arrived on my service dogs birthday 10/2/15 this year it was beutiful it also included some lights, and to my suprise a water bowl had been added, i don’t know if it was just a little some thing extra as a thankyou from them but it was very sweet, I am still waiting on my final order so i hope it come soon BLD has sent it so it’s some were in the post.

    One thing is for sure BLD will be my service dog’s shop from now on when ever i need something from BLD i will get it, i Recommenced BLD highly to every one weather you have a pet or service dog, BLD is brilliant
