Tank would not eat your dog. He is very friendly with people and all dogs no matter their size.He plays with all sizes of dogs at doggy daycare. Just don't walk in my house or come near my truck with out being let in and all will be good.All of your alls dogs would eat mine for a treat...even the yorkie!!! Mine's a pug mutt polm. He's a little over 3 lbs. and is about the size of a beer can. I cannot start the wheeler or the lawn mower without him riding with me.
