I totally understand how you feel. We were concerned when we moved our mare to another boarding facility. Thank goodness she is very social and it didn't take her long to adjust to the new herd.
I read another article called too attached in an issue of horse illustrated too. You included in th article that yuou at one point had him in Maine. This may just be a really big coincidence but I went to a summer camp and one of the horse's there was a morgan, looked alot like him and was named Snoopy.
