Whenever I leave "Flower" at home by herself, she chews something of "mine" up. There is only me and my 9 yr. old son in the house. When I won't let her out to play, she will go in the bedroom and use the bathroom on my side of the bed. Not only NO.1, but NO.2 also. What is up with that????????
I think Flower needs to be crated when you arent at home. Too dangerous for dogs, especially destructive ones and puppies to be loose in the house alone. Too many things such as electrical cords that are fun to chew but can be fatal for them to find.
People are like slinky's, not really good for much. But its still fun to push them down the stairs.
I would also strongly suggest obedience classes pronto along with the crate training. Sounds like you could have a control/dominance issue in the making since you mentioned that you personally seem to be the target of the distruction. As much as we love these bully breeds and as cute and cuddly they are when they are young it is important to put your foot down in the early years so that we can enjoy them for the rest of there lives. In my experience with both pittys and mastiffs it is much easier to teach good behavior when they are young then to try to retrain them when they are to large to handle ;)
I prefur to have my Bordeaux with fur instead of a cork and bottle ;)
