Re: Growling, showing teeth, biting
I agree with everything above. We also have a possessive vizsla, but he started to show possessiveness at a much younger age. We tried everything as well- being nice, being mean, etc. I hate the idea of trading the item for a treat, but I started out this way. Once he knew my approach towards him meant good things, I started asking him to drop it without a treat, picked up the item, THEN gave him the treat. We have a special stash of high value treats we ONLY use for drop it, so he continues to want to drop whatever he has because he knows he will get something extra tasty.
