Pitbull breeding

Question
Do male pitbulls show aggression after the first time they mate?

Answer
I don't know a thing about pitbulls, but it is not uncommon for male dogs to become more aggressive after they have been used at stud, particularly toward other males. Some dogs, particularly smaller ones, often start marking in the house. Dogs kept as pets are always better off neutered as they tend to be a bit more mellow with that drop in testosterone.
