Sam is a Collie, Shetland Sheepdog, Cocker, and Beagle mix. That's right, I did DNA testing to find out what ingredient went into my perfect little guy. He's a rescue. He's the smartest dog I've ever had. He can learn tricks real fast. He can also sing in a terribly annoying howl. Every time I play the piano he has to banished from the room because his singing is so loud and tuneless.
