I am new to the group. I joined because I am looking for some info on sheltie behavior. We have a 3 year old we adopted through a shelter 2 years ago. My best description of him is "autistic". He is smart, beautiful, and socially inept. He does not play with toys, balls, frisbees, etc. He is very loving with my husband and me but still skittish and will not come when called all of the time. He has stayed outside in the rain rather than come into the house when called and offered a treat. We only use positive training methods. We socialize him as much as possible but realize we need to do more. He has made strides since he first came to our home.
