While I was stocking up on cat food today, a customer came into the store with a HUGE dog! He was a Rottweiler/Saint Bernard mix, which apparently is called a "St. Weiler." He looked a lot like the first photo (Madison) at this website: http://www.dogbreedinfo.com/stweiler.htm
I didn't ask how much he weighs, but he looked significantly larger than my sister's 120-pound yellow lab. He was a real sweetie, just a big ol' tail-wagging happy boy.
And his name? Peanut! :D
