Looking For A Pet Sitter For 1 Dog In Salisbury

I am looking for help for a friend, Robert, who lives on High Rock Lake. He is 58, a retired Vet and has a 1-year-old dobie named Blu. Robert has had an accident and infection from volunteering in NC mtns after the hurricane that have left him having a very difficult time getting around with one badly injured leg. Blu is young and sweet, high energy, and just needs more exercise than he is getting right now. Robert has done a good bit of training with Blu so he wants someone who can help him work on his commands while he is getting exercised, as well. This is a kind and strong man and he doesn't like to ask for help.
