A world without dogs would be crazy. It would be lonely for most of us if we lost our favourite canine companions. Fortunately, almost every household in the US had had at least one dog. Dogs are animals that need special care and extra attention from us humans. Compared to cats, dogs are more active and showy to their companions. Cats just lie and sleep most of the day. It only moves toward you to get is dose of petting or to ask for food. Most of the time, cats would rather sleep or groom themselves.
