I think you are on to something Ruby, I think he wants in to be with us so he doesn't want to potty outside because he has our undivided attention. Heidi usually goes and is let back in so he has us all to himself.

I usually don't leave the house until 7:00, I just get up when my husband does so the dogs can. I am actually usually home by 6:00 but he goes out and dinner is not until the dogs get to potty and the cat box gets cleaned. There is no way to re-organize our work schedules the best we can do is come home at lunch. The longest he is home is if we car pool and that is 6 hours before lunch.
