What is the best way to socialize a dog aggressive dog? I know that socialization should have taken place at the age of 3-4 months, but I got Peanut at 11 months old. Anywho, theres still gotta be a way to curb her dog aggression, right? And while I'm on the subject, what is the best way to practice recall with a dog? Peanut knows a few commands, and "come" is one of them. The problem is that once we're outside, all that goes out the window. She's gotten loose before when I used to walk her using a collar, now I switched to a harness and although she cant get loose, she still pulls for everything shes worth. I was thinking about the dog park and school, but noone wants their dog around an aggressive dog and I can't blame them. Any suggestions?
