Dog.
Yep, yep that's a dog.
A little unusual looking though, no? The ears.
That's a Carolina Dog. The ears are characteristic and so is that fishhook tale. The Carolina dog isn't "man's best friend" either, a friend, not just best friend. Hasn't had as much contact with people. The theory, becoming more widely accepted, is that the Carolina dog didn't come to the New World with Europeans and hence didn't become as man-friendly. The theory is the breed came much earlier, when there were fewer humans, when there was a land bridge connecting North America and Asia. Ladies and gentlemen say hello to "Lady Jane," a Carolina dog, the first American dog.
