We have mutts. Two of them.
Taking them out in public, which we do frequently, is one long game of "Guess That Breed".
Let's start with Maisey.
People think Maisey is a Boxer, a Pointer, a Bull Dog, a Pitbull, a Terrier, a Hound, and all manner of boxy-headed breeds. Truth is, we have no idea. She was found as a stray on the streets of Iowa, dumped in a shelter, then pulled before her "kill date" by a rescue here in the Twin Cities. An awesome father/son combination fostered her for several months before we adopted her last spring.
So we have concluded that Sweet Maisey Potato Head is simply an "American Shelter Hound".
