I adopted a 3 year old white minature schnauzer 6 months ago. He is the most loving, energetic dog. He is definately a good dog except for one problem. Once he settled into our house he became aggresive towards other people who try to come close to myself or my daughter. He is extremely protective of us. He is fine once I get him settled down put until I do he barks and tries to go after them. Also if my daughter and I are tickling each other he thinks I am hurting her and goes after me. What should I do?
Thank you for adopting!
