My dog was attacked today by a neighbour dog. She had a nasty looking tooth mark in her side and was clearly in pain, so we rushed her to the vet. After examining her and stitching her up, the vet told us that the wound was already showing signs of infection and had been there at least 2 days. He insinuated that we were lying about the time of the attack and refused to discuss any other reasons for the infection. He put a drain in the wound and gave us antibiotics, but now I’m really worried that something else could be wrong with her. We weren’t lying! The attack really did happen only a few hours before and I noticed a mucousy discharge only minutes after the attack. Can infection set in that quickly? She was in good health and had no known wounds before today.
