I forgot to post that I did contact a sheltie rescue when I posted this on sheltie nation. Unfortunately, even though it doesn't get many dogs in the shelter, they I think are a high kill shelter. Henry, a black lab, was going to be euthanized today because he developed a cough. A rescue stepped in at the last minute. I think this sheltie will be okay but I am watching him very carefully. It just amazes me nobody is looking for him.
