I'm looking for a DOG TRAINER. I have two male dogs. One has been really aggressive and I got him fixed a week ago because he kept attacking and growling at my other dog. 3 days after getting him fixed he got real sick and was at the vet for two days. He's home now and it's hard to keep him from attacking my other dog. I don't know if it's because he doesn't feel good or just don't like my other dog. Club pet is closed today I can call them tomorrow.
