MAGNET WARNING - The strong magnetic fields near a neodymium magnet can affect pacemakers, ICDs and other implanted medical devices.  Many of these devices are made with a feature that deactivates it with a magnetic field.  Therefore, care must be taken to avoid inadvertently deactivating such devices.

 

Chances are if your dog is a trim active dog the Lucy fit is the right option. If you have a bully breed with a shorter ribcage or a heavy bodied dog, then the original fit will work best.

BrilliantK9 Custom Embroidered Harness Patch - Medium
Michele Challies (Hartford, Connecticut, United States)
BrilliantK9 Harness mesh

This is the 9th harness I've purchased from BrilliantK9 and the quality and craftsmanship is always top notch! The mesh harness are amazing for these hot summer days when my dogs spend a lot of time at the river keeping cool.
Also the easy on/off is great for competing in dock diving! Being able to customize the patches also makes the harnesses fun and easy to identify which dog's harness it is.

They're great, just wish they were more centered vertically. They do the job! I love the harness itself.

BrilliantK9 Ergonomic Dog Harness Large Dogs 50 to 80 lbs
Jeri Muntis (Las Vegas, Nevada, United States)
Pierce's New BrilliantK9 Harness

I recently ordered an ergonomic harness for large dogs. I love the quality of the harness, the ease of putting it on and taking it off, and the gorgeous pattern I picked out that looks amazing on my Vizsla!! I have a smaller one for my Miniature Schnauzer that I bought years ago. Both boys use these harnesses for Scent Work training and trials, so easy to use, and the boys go crazy when I put them on, they know what is coming!! Thank you, BrilliantK9, for making a great product and being so very conscientious about the quality, as well as your stellar customer service.

Excellent Product!

This is the second Brilliant K9 harness that I’ve purchased for my dog and I couldn’t be more thrilled. Not only is the product well made, but it doesn’t cause any raw spots from rubbing on my dog’s legs. And customer service couldn’t be better. When I purchased my first harness, it didn’t fit correctly. The company was responsive and helped me get the perfect fit for my dog. Love this product!

“BRILLIANT” says it all!!

Several( almost 10!) years ago I purchased 2 Brilliant K9 harnesses which are still in excellent condition with bright colors, magnetic latch as strong as when new and under MUCH use by 2 agility dogs. And because of the excellent quality of the harnesses this purchase was a name patch for my new dog, to go on 1 of the harnesses as it has been passed on to him! The patch is beautiful and matches perfectly with the harness.
Customer service, as always is top notch and I felt my small purchase was as important as any other.
Thank you Brilliant K9 !!
