For length, on shorter dogs, the neck gaiter will scrunch up a bit, and on longer dogs it'll cover more of their back. If your dog is on the longer side, the back leg straps are optional to use. The head opening is mostly for reference for pittie-types and other big-headed pups! For more info on jacket fit, check out our measuring guide . The Wilderdog fleece jacket fits over OR under our harness. If you prefer to use the back mounted d-ring on the harness, you'll want to put the jacket under the harness. If you prefer to use the chest mounted d-ring, the jacket can go over or under the harness. A leash clips easily onto a collar d-ring while the jacket is being worn.
