Tuxedo was the runt of the two puppy litter. We rescued him sight unseen. The runt grew into a 70 pound happy dog. Tux is his nickname; he has black and white markings which make it look like he's wearing a tuxedo when sitting down. He loves to assist us in filling up the bird feeders in the backyard as he keeps the birds and squirrels away as we refill the feeders. He loves his mommy and daddy as well as his feline siblings.
