Before Day 1

A few hours ago at dinner, my Mom proposed this idea that we train our dogs to be grounded. She wants my dog, FDR, to stop lifting his leg in the house. I will get rewarded, but I think the actual reward is that he will be able to roam around the house. I have 2 weeks for me to get FDR to stop peeing in the house. I have to work with him for at least 2 hours each day. It seems quite easy, but the hard part is how? How do I get him to stop lifting his leg? Right now, I have really no clue. I guess he could be near me all day while I do stuff. I just hope in the end that it works.
