My 6 month old puppy got overly possessive (i think) when i gave him his first veal bone to eat. Hi, gave my puppy his first veal bone this morning and let him go to town on it. After a little while i tried to take it from him and he growled, bared his teeth and snapped at my hand. He then ran off with it a few meters away. I tried again and the same thing so i picked him up till he calmed down. But he kept snarling and trying to bite me. Once he was calm, i put him down and he he listened to me for his eat command again. With his normal food, when i take it from him occasionally, he speeds up his eating but nothing aggressive. So my question is, should i be trying to take things like bone from him or let him enjoy it in peace?
