Now here's behavior that's unfamiliar to us. A dog who doesn't want a bone? Who not only doesn't want the bone, but adamantly refuses it? We can imagine a few specific circumstances that led to this.
1. The dog doesn't like any bones ever. (Unlikely)
2. The dog doesn't like this bone in particular, or else it's simply not her favorite bone. (Moderately likely)
3. It's Christmas, and this bone is not the bone that the dog asked for in her letter to Santa! (Highly likely)
