I have a 3 1/2 yr old Katrina rescue Pit mix and have been wanting to get a companion for her for a while now. I love pit bulls and would like to rescue one but I am so concerned about DA. My dog is really good with other dogs. Would it be safe to get a male pitbull? Can you usually tell if a dog is going to be aggressive towards other animals right away? Is it safe to leave another dog home alone with a pit bull during the day? I have heard that I should get a dog that is older because sometimes you dont know if a puppy will grow up to be DA. I live in a SFH with a large fenced in yard so it would be good for another dog. Any advice would be helpful!
