I have considered that but Stella is a little brute. Thought that bone would be too heavy for her to steal away...nope, she grabs it and jumps up on the couch with it! What a little stinker...it's good for Tank to be kept on his toes though I'd like to think she keeps him young!
Right now, in our house, we have FOUR big nylabones and ONE king kong. Whichever the one has, they look at the doggy next to them and want the one they have. So they all just kinda move around gradually to the next nylabone/kong along, until they start to think that the one they have isn't really the best one so eventually they all move along again. It's quite funny to watch!!!
