Tuesday is around 50lbs... she has a great personality, nice (longer) coat, good head, an easy keeper with a voracious appetite. However, this dog seems to only want to trot no matter how fast we go.... she is a very fast trotter and pulls but it is a quality I'm trying to get out of my team for mid-distance/stage/sprint. I think she has the head to be a leader, more than her littermates, but never tried her there.... she was running behind the leaders in a 12 dog puppy team. I think she is a really nice dog, but I don't know if she would be good for distance racing or not, but she is built tough, not too big, and trots like hell.... but she doesnt run.
