Our dog asks go go out over night every 2 to 3 hours. We don't give her water past 6:00. She still wants to go out. Even during the day its in and out. We have an invisable fence so we just let her out free will. She stays out for about 15 to 30 minutes. And stays in for 60 to 90 minutes. I am affraid to not let her out because I don't know if she will pee onthe floor. Any suggestions?
