Mobility Support Harness™ for brace and balance stability assistance

MSH Harness Size:

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:

• 2-4”

• 3-6”

• 6.5-8.5”

• 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 recommended size. Consider the BAH if a tall handle is required, it can actually be more stable in most circumstances because it absorbs excess movement.

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 Options

• 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)

Additional MSH Handle options: Select if desired

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.)

• Short Grab Handle ($): 

Clips to accessory D-rings, 8″ overall length, 5″ of leather. Sold separately as an accessory.

• 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. Semi-rigid option is recommended for most users. Custom made to desired length.

• Available but not recommended: Leather Guide Handle ($):Available in Flexible or Semi-Rigid LeatherLeather 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. Semi-rigid option is recommended for most users. NOTE: 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 than the Leather Guide handle version. *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. See the videos tab to see it in action.

MSH Replacement Parts are available:

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. See replacement parts here.

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:

You can also find cleaning instructions in the Owner’s Manual.

Important Notes: please read this before ordering

Due to the custom nature of this special harness, returns and refunds are not available on this product.

At Bold Lead Designs, we take the health and safety of your dog seriously. We have created these guidelines based on over 15 years of experience with this specialized equipment. 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 are physically demanding. A service dog should always be in prime physical condition to remain healthy.

Age, Size and Fitness:

Dogs should be at least 18 months of age before beginning harness work. The dog’s growth plates must be closed before starting to train a dog for harness work. This happens for most large breed dogs at 18-24 months of age and giant breeds need even longer to mature. Please allow your dog time to grow and mature as rushing into harness work may cause injury and shorten your dog’s working life. Additionally, if the harness is ordered too soon it will cost you significantly more money if your dog outgrows the harness.
Dogs MUST be in our recommended weight/measurement range set forth in the sizing guide for the harness to fit and function properly.
We want to see properly exercised, fit, lean, muscular dogs! Overweight dogs should never be expected to perform load bearing tasks; additionally, obesity contributes to serious health risks and can significantly shorten a dog’s lifespan. Consider implementing an exercise and fitness routine when the dog is “off duty” to keep him/her in good shape.

Consult the Pros:

Consulting a qualified veterinarian (orthopedic specialist or canine sports medicine physical therapist) is highly recommended for all service/assistance dogs that perform physical tasks. Radiographs (x-rays) or other tests may be recommended by the vet and are required by most service dog training organizations to determine if the dog is suitable for the demands of service dog work.
Harness users should consult a physician and physical therapist to determine what medical equipment is appropriate for their mobility needs. BLD harnesses are not intended to serve as, or to replace, a durable medical device such as a cane, walker, or crutch. Please understand that one should never lean on a dog to stay upright. Rigid metal handles must not be pushed or pulled on while the dog is in motion. Such use is not how the harness is intended to be used and could put the dog at risk for injury.

——————————–

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.
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. Users assume all responsibility for the safety, health, and care of the animal and human alike.

In your dog’s best interest, please understand that BLD may decline an order if we believe a harness could be harmful to the dog because of age, size, or unreasonable expectations.
