All 3 of my dogs are outside the majority of the time (mainly when everyone is out of the house, they can't be trusted inside without supervision!). They have an array of toys ranging from footballs, volleyballs, tug-o-wars, squeaky balls, and Oscar has a strange obession with wearing sacks like capes, so they keep him occupied! We keep a huge bucket of water outside which we need to refill every day, and we don't leave them any food outside because they wolf it down so fast it never lasts! But seeing as your puppy will be by himself, he will get lonely very quickly. So I would suggest getting another dog to keep him company, but I don't know how your parents would react to that idea.
