I just wanted to say you are getting excellent advice from Quicksilver. While I may not agree with your "tactics" in training your gf's little guy, I commend you for researching and seeking out the information needed to properly housebreak him.
Now with that being said, I want to thank you for your service to our country. My hubby was in Desert Storm and was in Iraq 2004-2005 doing medevac missions (he is a devildoc) so I know what being in those kinds of conditions can do to a person and a family. Again, thank you.
