Dogs aren't threatened if you earn more than they do. Dogs mean it when they kiss you. Men can buy you presents. Men don't have to play with every man they see when you take them around the block. Men are a little bit more subtle.
Dogs have dog breath all the time.
Men can do math stuff. Men don't shed as much, and if they do, they hide it. Dogs don't cry. Dogs love it when your friends come over. Dogs don't care if you use their shampoo.
