It is staining his fur with pus and has been smelling bad. He doesn’t let me touch it and hasn’t been eating at all. I was wondering if there is anything I can do at home to help alleviate his pain and clean his wound. He is 3 years old Male and his breathing seems to be heavy. I believe what may have caused this is when I gave him a shower 2 days ago and he started scratching at his chest at the wound which opened up. Right now he just been sitting around staring at the floor or sleeping. Please help me I want to do anything I can to help him but I can’t take him to the veterinary
