Is there anything more fun than watching one of your dogs chew on and swallow a treat he really doesn’t like just so his housemate can’t have it? The reluctance with which he is chewing is hysterical. But for so long as his buddy is sitting next to him watching every bite, he’s not giving it up. He will eat it no matter how much it makes him want to gag. Because it’s his and the other guy isn’t getting any of it. And it is this mentality that has led the male of our species to start just about every war in history.
