I'm afraid you are between a rock and a hard place.The only way to have a well trained dog is to make the time to train him.Even if you sent him out to an off site trainer for a few weeks you would have to find the time each day to work with him on a one to one basis to make the training work for you. I'm sorry you are in this position. If you do decide you cannot find the time for this "teenager" dog contact the breeder you got him from. Most responsible breeders take their pups back whatever the reason. Paws crossed it doesn't come to that.
