Tupac is a putt bull border collie mix. He is well behaved and potty trained and minimally trained otherwise. He knows the basics, such as sit and stay and come and he is very smart. He’s very sweet but he barks at men and in my dorm we can’t have a barking dog. Other than the barking he’s a very good dog for 4 months old. He doesn’t chew anything except what is his own, he doesn’t bite, he isn’t aggressive at all, and he has no issues with other dogs or women.
