LOL I used to have that problem with my dog. I started calling her so I could let her out in the backyard and when she was done I'd give her one of her favorite treats for doing her potty. Now she can't wait to go out in the mornings because she knows its treat time. Sometimes during the day she acts like she has to go out so I let her out and then she just stands there and then wants to come back in thinking she will get a treat...not. No reward for just standing there...she is too funny! Here she is when she used to stay in the bed.....
