Clearly the best would be not to uproot your dog for a whole year. Why not try leaving him with your family but get a person to come in each day and do the necessary things such as feed and walk him. There are companies that offer this service. A friend or a young person living in the neighbourhood might be able to help out if you offer a fee in return. I understand your dilemma... I get anxious just leaving my dogs for half a day at home alone!!
