Happy you found us! Congrats on your new baby!
You can find TONS of info on potty training by doing a search. Of course it is one of the MOST popular subjects here!
Basically keeping your pup confined until he learns the ropes is the best way to go about it. Crate training or using an exercise pen seem to be the most popular methods, as well as praising and rewarding when he potties where and when you want him to! Never scold for wrong pottying!
GOOD LUCK!
