>Most powerful: Jake
>Best smart dog: Brain
>Take behind the shed: Brian Griffin
If I had to choose one to adopt, I'd choose Brain for smarts, loyalty and resourcefulness. Courage would've been a good choice if literally everything didn't make him scream in the middle of the night. Brain can literally do everything Courage can without being such a pussy about it.
Snoopy is cool but I don't think it would feel right to OWN him, he seems content to do his own thing a majority of the time, he and Jake seem more like people than dogs.
Peabody is too smug for my tastes. Brain at least still seems like a dog.
