Description from the vendor website:

The Overcoat Fuse distills years of designing harnesses and apparel into a single jacket-harness combo, giving dogs who typically layer gear a seamless solution for getting outside in cool weather and light precipitation. Simply slip on, clip in, and go with this rugged workhorse of a jacket that has a water-repellent coating to shed light moisture and a fleece lining for added coziness.

The integrated harness means you can leash up confidently at two leash attachment points: one on the back and one at the chest - great for redirecting dogs that pull on leash. Stash pick-up bags or small essentials in the two zippered pockets, and you've got a coat that's ready to go whenever you and your dog are.
