Coming in to Major staring me down intensely, my boyfriend asks "what's he doing?" to which I responded "he's just messing around with me" and sure enough in a few moments Major broke his stare, did a goofy spin and jumped in my lap and "bit" (mouths without using his teeth) my nose and started rolling around on my lap with joy. So he asks me "why does he do that?" and I say "I dunno, he's just trying to be funny". Could that really be the case? While Major is often very serious for a Boston, I sometimes think he has a sense of humor. Does anyone else get the sense their dog has a defined sense of humor?
