BnB are quite the characters (if you haven't guessed). They do this song and dance when it comes to a rawhide...
Baxter: I want it!
Bella: NO I want it!
When one has it, the other spends an inordinate amount of energy trying to distract or otherwise send the other one on a snipe hunt so that rawhide can be stolen in victory! Most of the time, Bella doesn't really want it - she just doesn't want Baxter to have it. Baxter, on the other hand, is more food driven and would rather have it all to himself. This video gives you a little sample.
