Our Training Dog Harness with 2 Reflective DO NOT PET Patches helps to clearly identify your service dog as being in training. The patches are attached with Velcro to allow you to easily remove them and replace with regular service dog patches such as when your dog has completed training. Featuring an adjustable belly strap with a quick release buckle, it is the easiest service dog vest harness to put on or take off and is perfect for dogs that are still undergoing training. On top of the vest is a built-in nylon handle and a welded D-ring leash attachment for added control.
