Please don't give up. Try taking him out on a leash for elimination and keep walking him. Tell him to "go potty" or whatever phrase you want to use. As Nick said, be calm. Eventually he will do what needs to be done. Then praise him like crazy and give him a tiny treat. Act like it is the most wonderful thing in the world. This way you will know that he has "gone". You should take him out right when you get up, after he eats, after periods of lots of activity, and right before bed. You may have to take him out five or six times a day. I know this is awful weather to do this in, believe me, I had to do it myself with my dog, Hannah, who I am sure holds the world's record for taking the longest for housebreaking. I won't tell you how long it took, but that eventually she was completely housebroken. She now takes care of everything on her own. Please don't give up. I have living proof that determination, commitment on your part, and a lot of hard work do pay off.
