A dog doesn't care if you're rich or poor, big or small, young or old. He doesn't care if you're not smart, not popular, not a good joke-teller, not the best athlete, nor the best-looking person. To your dog, you are the greatest, the smartest, the nicest human being who was ever born. You are his friend and protector.
Louis Sabin

If your dog doesn't like someone you probably shouldn't either

Every dog must have his day
