I do wish more people would respond to your thread. Actually I do think your dog is bored. Border Collies are one of the smartest breeds and were bred to work and be useful. I don't have the answer but I would recommend you search on the Internet to find people who are very knowledgeable about this breed to get some ideas on how to channel his intellect and energies in a manner that will alleviate some of the stress he feels right now. I would also suggest you get breed specific books from your library or bookstore and see if there are suggestions that might be of use. Your dog is absolutely lovely and you are right to be concerned.
