Neither understands what you see in cats. 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. Men don't eat turds on the sly.
Men open their own cans.
Dogs have dog breath all the time. Men can do math stuff. Men are strong and like to lift things to prove it. Men don't shed as much, and if they do, they hide it. It's fun to dry off a wet man.
