<i>-Dogs are more loyal to humans</i> --Mr. Graves

Dogs are loyal to their food source.

<i>-Dogs won't attack you if you bother them. (assuming they know you/are their master)</i>

Some dogs will attack anything that moves. Dogs are aggressive (and evil).

<i>-Dogs do what you tell them too if your trained</i>

Cats don't need to be trained.

<i>-Protection</i>

That's what door locks are for.

<i>Also, every dog your parents ever owned isn't every dog in the world. You really can't go by that.</i>

You're a communist.
