I've had quite a few dogs in my 22 years, a few Labs and some Shih-Tzus. I've watched my aunts Rottweilers and boxers over might multiple times. I've also watched my friends PitBull and German Shepard multiple times. With these dogs I've watched them at multiple ages from weeks old to near the end of their lives. As I said in my headline I view dogs as a part of the family and will always be treated as such.
