Introducing - Maverick! Maverick is a 4 year old male blue merle Shetland Sheepdog (Sheltie). Recently, Maverick became a therapy dog so he can go to hospitals, retirement centers, and other places to visit people in need of a doggie pick-me-up. Currently he goes to the Longmont United Hospital to visit patients in the orthopedic area. We've just started, so stay tuned for more updates to come.
