I am glad I dropped by to read this!! I have a new puppy (just under 17 weeks) and man O man.. I don't want my pup to act like that! I think this has renewed my drive to really social and train her well so she's lovable and not a pest! Thanks for posting on this topic.
Yes, if I ever have a puppy, I will definitely train her, too. I just wish my friends would see training as a good thing. Instead they see training or obedience classes as a punishment.
Puppy is not happy. She needs so much attention and she is not getting any because my friends are never there. I stopped by to feed her last weekend and she just wanted to play (while I wanted to shop!) I didn't spend too much time with her, but I felt so bad for her.
