You should teach him to go to the door whenever he needs out. A dog is never fully housebroken until its owner knows the signs that he needs to go out. Try hanging a large jingle bell from the doorknob to your dogs nose level. Each time you let him out, show him the bell first and get him to sniff it until it makes a noise, says look at this enthusiastically and point to get him to sniff after a while he should start going to the door himself and hitting the bell and waiting for you, dont make him wait too long. You won't need the bell anymore after a few months, and you will be able to let your dog have the run of the house worry free, well until he hides away with your favorite socks when you aren't looking. When you are at work I would crate him because a pup that age could get in real trouble when nobody is around. My toller was housebroken at 12 weeks, which is early, but I still crated her up to a year when nobody was home. There are other things to learn besides housetraining, like which cords not to chew not to get into the garbage, so there are still reasons to crate. How long are you away at work each day and how long must the pup stay in the crate? Did you paper train at all? It is not something I recommend because if you take too much time to answer the "door bell" the pup may find it quicker to just find a magazine on the floor.
