* Important notes: Dogs should be physically mature (growth plates fused) before beginning harness work. Dogs must be physically sound and of appropriate size for mobility work.  Please be sure your dog is the right age, height, weight, and strength for the assistance you need. Consult a veterinarian to determine your dog’s suitability for harness and/or mobility work. Tall handles apply more pressure and torque to the dog than shorter handles, due to the laws of physics, and may indicate the dog is small for the task. A dog should never be expected to replace the heavy-weight-bearing capacity of a cane or crutch.

    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.

    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.

    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!

    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!

    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^) ]

    Journey and I have been using our mobility harness for a month now and I am really impressed with the fit, craftsmanship and overall professional look. Not only that, it’s safe and comfortable for him, provides the support I need and makes us really able to work together as a team.

    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.

    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.

    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.

    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.

    This is by far the best support harness ever! Killian adjusted to it very well. The harness and my wonderful dog have saved a fall more times than I can say not to mention the never ending aid in balance support. Thank you BLD for a job well done. No regreets. Will do future business!!!!!

  14. 5 out of 5


    I wish I could give Katrina ten starts. I’ve had my harness for less then a day, but I’m already so much more confident in my balance that I can actually walk with my head up to the horizon, a first in a long time. I was blessed to live close enough to Katrina that she could do the fitting work in person, and she is just the sweetest, most helpful person I could have hoped to do business with. I’m so happy.

    My harness handle doesn’t shift or wobble- at all- not even a little bit. The ergonomic handle is worth the extra change, it has the perfect positioning for my hand and elbow that makes using the harness feel so natural.

    We did also get the cape in red and the ill strap. Maple looks professional and stylish.

    Previously I had another harness which made Maple harness shy and resistant to work, along with taking forever to put on. In the bold lead, maple is clearly comfortable and adjusted within hours of wearing it.

    I will from now on only shop and support bold lead design for all my SD needs.

    I just wanted to say thank you for making such awesome harnesses. You really made a harness that is comfortable for Raven and me. She loves this harness and prefers to work in it even on my good days!! I would recommend this harness to anyone that has a mobility service dog!! Its very durable and long lasting and its great that we are able to replace parts if needed instead of buying a whole new harness!!! Thank you!!!!

  16. 5 out of 5


    To All Who Crafted Mojo and My Stability Harness…..THANK YOU!
    The product is everything you say about the quality and craftmanship I receive- It’s one to be treasured and used with delight by us both! I am so glad that your company was accessed for my needs and the need’s of others. Best of luck and may your business remain five-star!

    Bradley’s new harness arrived today!!!. . . It is wonderful. Bold Lead Designs this is the best harness Bradley and I have ever had or seen. He didn’t fuss at getting it on, he just slipped right into it. It’s well padded for him. The handles are perfect for him and for me. Your harness is the first one I’ve ever seen that has the extra strap under his stomach which makes it so secure for me. And the release buckles will be easier than anything we’ve had. The way you have the front chest straps make it better for Bradley and sturdier for me. I’m really happy. I like the release on the handle too. It will allow him to go under the table at restaurants and in church. This is very well designed.
    I will send pictures.
    Thank You Bold Lead Designs and Thank you National MS Society

    I had been debating getting a new harness for a while. I had purchased other harnesses, they either slide around or my service dog was so uncomfortable in them that she didn’t even want to put them on. I got this one in the mail and she couldn’t stop sniffing it. I got it all set up put it on her and she acted as if she wasn’t wearing a harness. She was able to jump in the car, trot around and definitely felt more comfortable that any other harness. It was well worth the month and the mobility handle helped greatly with my balance/dizziness problems. I could feel the dog move underneath the handle unless other soft handles and was able to use that very easily even without putting much pressure on the dog.

    I ordered my MSH about 18 months ago and it has been a pure godsend for me!
    Several times when I have gotten overbalanced I was able to hold the handle and steady myself instead of falling.
    Rachel my beautiful standard poodle is so comfortable in the harness she will fall asleep under the table when we go to restaurants, or for coffee. Rachel totally approves of the fit and feel of this wonderful harness as do I. And the over the shoulder leashes are awesome as well, I have sent many many people to BLD with the highest praise for the products. I will never buy a leash anywhere else!!!

    Awesome products Katrina and crew.

    My Lola and I love our Mobility Harness!!!!!!! Most comfortable ride out there. I tried them all. They all hurt my back. ONLY BLD harness doesn’t hurt in fact only comfort. Thank you so very much for helping me and giving me a easy, lightweight, problem free harness. Lola and I as a team feel less of a weight on our shoulders every time we go out. Pun intended. AND you guys were sweet to me even though I don’t talk very well taking our order. Thank you.
