I remember that episode! I think it was from the first season- it was part of the reason my dh was so resistant to me getting a yorkie. He didn't want a spoiled rotten pooch like that one.
I'm just always amazed at how bad some of the dogs and families are on those shows. So many of those problems could have been avoided or minimized if people would just put in a few weeks of training early on
The ones that always amaze me are the women who let their dogs growl or nip at their partners when they try to come to bed. Duh! To me that's a no brainer situation.
