Please don't give up on him. I recently went on vacation for two weeks, and left my four with my two grown up kids. I came home to the most horrible stench and poop marks all over my carpet. It seems the kids changed the dogs food while I was gone, and it made them sick. It took a little while, but I got them back on track. Just take it one day at a time, and you'll both be fine.
