Okay, I suck... I donâ€™t know! Someone is always up before 6 in this house and whoever gets up lets the dogs out in the morning. After that, its anyoneâ€™s guess. If they ask to go out they go out. If they ask to come in, they come in. They have two slave children who mindlessly open and close doors at their bidding. Its kind of funny to watch how well trained the kids are actually. They go for about 10 hours at the most on days we both work, but most of the time DH comes home at some point (to potty - the irony) and lets the dogs out.
