Well, Liz, we also thought that he is much younger. Doc B said that he would guess him to be between 1 and 3 years old, but probably closer to 1 because of his puppy behavior. You should have seen him tonight when I came home. Mike and I took him out to the backyard by himself and played catch with him...it was a riot. He was jumping around like a wild man and throwing the ball around and chasing back down...he is a true Weim! lol
