My dog has sores on his back that seem to be spreading. I thought that he had been in a fight, but now I wonder if it is something else. He scratches the area like crazy.I put neosporin on the area , but that doesn't help. The area also smells bad. PLEASE help!!! Louie is a 6yo chihuahua.
This sounds like a skin infection and needs to be addressed by a vet visit. Good luck, vetcare
