Women Are Like Cats, Men Are Like Dogs No matter what you do with a dog, he is man’s best friend. A dog will never leave you, no matter what happens. Dogs will come right up and demand attention from anyone, even a friendly-looking stranger that appeals to them. They don’t understand the concept of rejection if a stranger pushes them away. They will come right back for more. Dogs will feel an instant attraction, an instant affection for a total stranger, and run around obeying commands at the drop of a hat.
