I don't know if Boxers are named such because they box, but Atticus definitely does. Box, that is. Takes his paw and just smacks the other dog in the face, playfully. It's the way he almost always tries to initiate play with another dog. Lots of dog-owners who he approaches to play in this manner think it's threatening or aggressive behavior, but I know it's just Atticus' way of saying "let's play!" Is this typical of Boxers and atypical of other breeds?
