my adult GSD, 5 years old, who is VERY protective will get along with another dog? A puppy? He's had one dog friend before, a very friendly pitbull, and they got along quite well. I think there were some incidences that they got into fights, not sure whether it was a fight or just rough playing. But I'm getting a puppy Siberian Husky in a few weeks, and I'm wondering, do you think he'll get along with the puppy?
