re: How to handle/potty train a puppy while at work all day?

I got a 9 week old lab. I luckily got her at 5.5 weeks during the holidays and it made it a little easier. I leave her out in the back yard during the day and she is fine. Just puppy proof the yard, make sure the pup can't get out. The worst she does is run behind the bushes and is starting to dig a little.
At night she sleeps in my room and wakes up to go outside once a night. Can't wait till she can hold it all night
