Coop is all over the place right now too (3 1/2 mo). Tail looks way too long and his rear legs are a tiny bit longer than the front (or that is how it looks right now). I swear he is all angles, joints, head looks smaller now than the rest of him. When he runs, like a child, arms and legs are all over the place until he really gets going, but then the rear legs are more powerful than the front...and he ends up, down, with legs all over the place! Tail, when happy sticks straight out and I swear it is as long as his whole body. Such fun and will enjoy watching all the pieces come together.
