Dog possessive with bones
My 1 year old puppy is very possessive with her bones and toys around other dogs. She has no problem with humans (adults or children) taking them from her, and doesn't react at all to that, but if there is another dog around that she is familiar with and it comes near her bone or we pick it up while they are near she will snap on them and try to fight them. I don't know what to do, because everything I read seems to be for if she gets possessive when I try to take them, and that isn't the problem. Please help! She lives with 2 other dogs, so it can be quite a problem!
