Kenda weighs 24 pounds, and she's a shelter mutt (suspected border collie mix, but really we don't know.) Here's a picture of her build. Sorry for the doofy expression; she was chewing a stick. She's full-grown at just over three years.
Caeda is a year and a couple of weeks, and at last weigh (2 weeks ago) she was about 63lbs.
The only pics I've got handy are the one in the signature (9mo or so), and my avatar (~4 mo). She doesn't look much different than the pic in the signature though...scaled up a tiny bit and a more filled out chest.
