To get the most accurate size harness for your dog partner, measure the girth of their chest, around the widest part of your dog's torso right behind the front legs, with a cloth tape measure. If you don't have a cloth tape measure, you can use a piece of string and measure it with a rigid ruler afterward. Make sure there's enough room for about two fingers between the harness and your dog’s chest for comfort.

The girth and front chest strap are both adjustable making it easy to achieve the ultimate fit for any breed. All seams are bound and reinforced for added strength and to maximize durability & longevity.

Trained Service Dog. A Service Dog is defined as a dog that has been individually trained to do work or perform tasks for an individual with a disability. The task(s) performed by the dog must be directly related to the person's disability.

A Service Dog On Duty Vest, although not a requirement in accordance with the Americans with Disabilities Act, is the very first form of identification to show the public that your dog is not a pet but is in fact a working service dog.
