hey good idea about nuking the chewies. My dogs(shitz tu and bichon frieze/shitz tsu) teeth are so small and some the bones are huge. Anyway when i walk the shitz alwys trys to dominate and go first , t then the bichon then Me .After my bf and i got together 3 years ago i noticed the shitz would always growl at him and no way could he lead if the shitz could help it. So the new order was the shitz tsu, the bichon, Charlie (we joke that he is the third puppy) and then me. I then overheard Charlie lecturing the dogs one day. I'm the alpha dog around here. So far the shitz tsu is winning.
