Addie, my 18 month old lab-pit mix, would be an athlete. She runs, jumps, etc. etc. constantly. I have never seen her worn out.

Jake, my 13 month old Golden, would be a surfer-bum. He loves to swim and lay around. He's very smart, but comes across as a big dofus.

Cody, my 8 year old lab-dalmation mix, would be one of those people lounging on the couch at the therapist. He's become a bit neurotic as times has gone on.
