More than 8 years ago I purchased this harness for my border collie to use at agility class/competitions/other dog sports and it's still in great shape despite heavy use and many, many washings. When I was looking for options for my 2 year old pup, it was a no-brainer to just buy a smaller version of the exact same harness. Easy to adjust to the correct size, easy to put on and off, looks great, and custom velcro patches are a fun bonus. The high quality and durability of this harness is amazing. Folks, I encourage you to support small American businesses doing quality work like BrilliantK9!
