My puppy, and her breed in general (American Pit Bull Terrier)

:

Well, okay, as far as wild animals go:

The gray wolf.
And...

red foxes, especially calico-colored red foxes, like the one pictured here. For some reason, though, I have this odd feeling that some really uneducated person could mistake a calico fox for an odd-looking rare dog breed or an odd-looking mutt.
And, my 3rd most favorite wild animal:

The much hated coyote. People know them as killers of small dogs and small children, but honestly, any medium/large wild predator will go after and kill small animals and small children. Hungry wild animals can tell little difference between a Chihuahua and a hare/a human baby and a fawn. Although coyotes are known to thrive well in urban and suburban areas, unlike many other predators, like wolves.
