A harness that does more than just look great!

Easy On Easy Off and fits like a comfy T-shirt

The BrilliantK9 Ergonomic Dog Harness is designed to keep pressure off the neck, and allows freedom of front-end movement, while limiting the dog's effectiveness at pulling. Because of it's innovative one hand buckle, it is also extremely easy to put on and off even for people with impaired motor control. Standard side release buckle is also available as an option.

25 fully adjustable sizes for a perfect fit!

From teacup to giant - we ensure each dog gets the perfect fit. Other harnesses are offered in limited sizes, and no matter how adjustable, they do not fit the range of size from the smallest to the largest. Poor sizing leaves dogs uncomfortable, causing rub spots or dogs back out. Have a dog that's difficult to find something that fits, and works?

Allows the dog to walk and move in their natural gait.

Traditional harnesses and collars put pressure on the dog's head, neck and rib-cage and promote pulling and straining against the device as a natural opposition response to restraint. The BrilliantK9 girth strap is behind the rib-cage, with the leash attachment is mid back (behind the core strength), making it hard to pull if there is nothing to pull against. Their spine is in alignment, and they are able to flex at their natural pivot point.

Long lasting and durable materials are selected for our hand crafted harnesses!

BrilliantK9 harnesses durable design and lasting quality will remain your dogs treasured walking tool for many years. BrilliantK9 delivers only the finest in Contemporary American design and craftsmanship!

Vet approved!

I am a veterinarian doing certified chiropractics on animals since 2007.  I am always looking at different products to benefit my patients.   The BrilliantK9 harness has been one of my favorites— so much so that I use it on my own dogs.  It is perfectly balanced, easy to use, and puts very little pressure on the neck.   Many of my patients use this harness already and I will continue to recommend them.

Amazing product!

When my dogs need to be on a leash I always reach for my BrilliantK9's.  I find it fantastic for a multitude of uses, allowing the dog to move comfortably whether they're running and playing, hiking, a Service Dog working with their handler, or walking to the agility ring.  The BrilliantK9 is Pogo approved and we can't recommend them enough!

Great for walks!

This harness has changed my relationship with my beloved (but big time puller) Aussie. Our walks went from frustration and a battle of wills to pure pleasure. Thank you so much for this wonderful product.
