Hello! First I would like to introduce myself. My name is Adam and I am new here and I am looking for some advice from the experts out there or anyone that has expierence with "The Boxer" My wife and I did a lot of research about the breed before getting Bosco (he is our Boxer). My wife has had many dogs growing up and has expierence so we are not new to the dog scene. We wanted a dog that would be good with children since my wife was pregnant at the time we purchased Bosco. When our baby Kate arrived Bosco welcomed her with open paws :) and has been her best friend ever since. Kate is now almost 2 and they are inseperable. Bosco is now just over 2. Now here is my problem. Bosco has become very overprotective of Kate and my wife to the point he is scaring me. If Bosco does not like you he becomes very agressive. I know he is just protecting my daughter and wife and to a point this is good. I just dont need him taking someones arm off.....lol Now when I am around he is fine. Its almost like he knows I can take care of myself but its a whole different story with my wife and daughter. In all the research we did we never came across anything saying this breed was agressive. We actually read nothing but good things about boxers. Am I over reacting or should I be concerned? Is this normal for Bosco to be overprotective of my daughter and wife? I just dont want any of my friends or other family members getting hurt and then having to get rid of Bosco because he bit someone. Thanks in advance for any advice. Adam
