Penny Lane wasn't very interested in other pups either. Last week there was a little pit bull puppy biting her ears and trying to get her to play (not during playtime, though) and Penny Lane just laid there and looked at her like "What are you doing? It's learning time" Then during play time she would sniff the outer edges of the room then play with the other pups for a bit when they came to play with her and then she left them and went back to the people.
