Very interesting thread...
Roxey, I would have to say her one and only downfall is digging. She does it much, much less than she did when she was a pup.
Huney, if she's really wanting in the house she'll press her nose to the door and paw a little, and when we first start on walks she'll pull but then after a bit she'll quit.
Bon, MY only problem with him is his jumping. Not that he jumps on us, but he gets too overly excited when we have company and will jump on them. It only takes a few minutes for him to calm down but this behavior is unacceptable since he's so huge...he could knock you down.
He's been aggressive towards other dogs but I don't fault him for that.
Now that we've stated our dogs behavioral problems we need to say their good characteristics, we sound like we have bad dogs :p
