25 fully adjustable sizes for a perfect fit!

From teacup to giant - we ensure each dog gets the perfect fit. Other dog 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?

garminn-in-harness

Allows your 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 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.

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!"

So versatile!

"I absolutely love my BrilliantK9 harness for all of my dogs! I use these harnesses for everything from my dog walks, a variety of dog sports and swimming/paddle boarding. I love how comfortable they seem for my dogs and how easy they are to get on and off!"

I love the harness and great color. I really love the magnetic speed buckle. So easy to hook and unhook with no squeezing for arthritic fingers. The fit is perfect because I had them pick the size from my measurements and photo of my dog. I couldn't be happier.

Finally a Harness that doesn't irritate my dogs front legs

1. Love working with small business. I spent time on the phone with the owner to fine tune the measurements for my dog.

2. I love all the design choices.

3. I especially love the fact that there is no gimmick about how it won't chaff the legs because IT SITS VERY NICELY OVER THE GIRTH, doesn't come close to the front legs!!

Exactly what I wanted

My border collie (45 lbs, 20.5" tall) had been using my older dog's Dixie size for nosework, but needed his own, as it was too large for him. I thought he needed an Ares, but I used the "Let Us Choose the Correct Size" form just in case, and I'm glad I did, because Lucy Medium was suggested, and it fits perfectly. I love the color too... I was hoping it would be a bit more vibrant than it looks in the website photo, and it is.
