Hannah graduated the puppy class around two weeks ago. She was in class with a lab and a pitbull. The pitbull was around 40 pounds. The trainer did not let them get close to one another. We each had portions of the room to ourselves. There was one class that we let them meet each other. The trainer was close by and the dogs got along beautifully. We learned the proper way to introduce dogs to each other. I think that the class was a great opportunity for socialization plus Hannah learned a lot.
