i need help, feel like im on crazy pills. Dog fur appears to be fading exactly where the dogs harness straps are. Before anyone suggests visiting a vet, been there, done that, dog is in great shape for the shape it's in. So i am wondering if the fading fur is being caused by harness strap friction or possibly sun bleaching. Next question would be will the dogs fur return to it's naturally darker color if discontinuance of the harness is implemented?
