One thing that has worked well for me in training hard headed labs is to punish them with what ever they destroyed( Im not advocating animal abuse but the dog needs to understand who is the boss), and then tie it to there collar for 3 or 4 days. I had a lab that didn't understand how strong he was and liked to play with the cats, Thinned the cats population but was not veiwed lightly by the family. Another time was with the chickens. Once we tied them to him after he killed them, we would leave him in his kennel for a day or two. He would never look at them again, in fact he would leave the area if he saw them. As for house hold items this method works equally as well with a little persistance.
