Service Dogs

Service Dogs spend many hours in their working harness. Keeping them comfortable needs to be a priority to keep them working at their best. We make our service dog vest harnesses here in the USA by hand. Our service dog harnesses hold up and stay looking nice for years to come, as long as you machine wash with no bleach and hang dry. We don't use foam or felt, which cause heat build up and rot from the inside. Our service dog vest harnesses can be used as an Evaporative Cooler on Hot Days by just getting it wet (don't use Ice Water). The Unique buckle design allows for one hand operation. Our working dog harness is complete with 2 side packs that are removable for easy access to documentation. 2 Patches - SERVICE DOG Do Not Pet. Utility Loop for Mini Flashlight or Poop Bag Holder. Our service dog harnesses are trimmed in with a Retro-Reflective material. Free Shipping is included. 

Assistance Dog Harnesses - Please contact us so we can make the correct options for you. 

You should machine-wash our service dog harness vest with no bleach and hang to dry.

Our service dog harness has a unique new Speed Buckle design, which allows for one hand operation.

We also sell a variety of service dog accessories, including patches and extra side pockets for storing information.


If you're looking for a unique service dog vest with pockets for your specific breed, you're in luck. We have unique sizing based on the build and weight of the dog to ensure a proper fit.

If you do not currently have a BrilliantK9 harness we recommend you contact us for proper sizing to ensure the dog is comfortable. The design of our service dog harnesses is based on our BrilliantK9 Ergonomic Dog Harness, used and recommended by Dog Sport Enthusiasts across the country.
