If you're partial to really smart and well behaved dogs, I think we might have one for you. Molly looks like a German Shepherd/Australian Cattle Dog mix, and it doesn't get much brainier than that in the canine world. Molly and Madison were brought in together and we would love to keep it that way, but they are both well adjusted kids and are not reliant on one another. If you're only adding one, Molly is smart and fun! If what you seek is two, we'll add Madison for you!
