So my first boxer baby who is now 11 and going strong with energy is an American boxer and my new addition I am getting this Friday is a European boxer. Now I've heard that the American boxers are typically more high strung and more aggressive and the European boxers are more laid back. So cash my boxer who's 11. Has always been hyper and jumpy which I would think would be typical boxer if reading a description and he is very protective of our family which can make him aggressive in certain situations like protecting our yard and stuff. You can't come past our Gate but he's awesome at a dog park. I firs what I'm asking is should I expect a more relaxed personality with my new European baby.
