I could easily take anything out from my dogs mouth by saying drop it, (even my maid could do that with no problem) well maybe I am lucky.
My male once tried to protect his bones (and it was long ago when he was 5/6 mo) by growling, I just growled him back

and took it up, the fun was over. Later I called him and gave the bone after asked him doing some tricks, and in few second immediately I asked him to give the bone back to me by drop it, he looked doubted, but finally he gave it to me and I praised him.. and he could have the bone back to do all the chewing party.. (just wanna show him that I was not a threat).. repeated few times after giving him bones.. soon the dog would know.
