We are up every morning even on the weekends by 6:30 and the first thing we do is put the dogs out. The days of sleeping in for us are over. During the day they stay in for a while then go out for a while. At night we let them out about six, we watch t.v. and we all go to bed at nine, but my husband walks them out and makes sure they piddle before they come in and they sleep until 6:30 again in the morning. We haven't had any accidents for about two years and if Daisy has to go in between these times, she will go to the back door, Perry can hold his pee forever.
I think a routine is the answer.
