BLEAH

strangest mix I have seen was Sparky who looked like a a black lab lying by the couch. Then he started moving and I realized that he had actually been standing up. Somebody's black lab had escaped and met a beagle. The result was a slightly overweight, extra-droopy black lab with 3 inch legs.
