Two months old is still pretty much of a baby. They just don't have a lot of bladder control and need to go out early and often . Say the puppy goes outside, goes potty, comes back in and then play, play, play. After a lot of romping, he may need to go right back out again. I've had dogs who were easy to house break and one who I was afraid would never make it (look to the left)..... but eventually she did! Tell your friend to read up on puppy raising. A lot of good books are available at the Library. One in particular I am prone to recommend is Good Owners, Great Dogs by Brian Kilcommons and Sarah Wilson.
They have an excellent website as well. Here is the addy for the housebreaking section. Tell your friend good luck and don't give up.
