Dog barking to go outside at 3am
Hello. We have two 5 year old, female weimaraners. Awesome dogs. However, in the last month or so one of them gets up to go outside every night at around 3:00am. She goes outside before we go to bed and pees. When she goes out at 3am she pees and poops. She'll bark outside our bedroom door and then downstairs at the back door, back and forth. We've tried to ignore her, but we have a 2 year old who wakes up to the barking.
Any suggestions on how we might break our weim of this habit? She's housebroken, but has peed in the house on a few rare occasions, so there is the chance that she'll do that if we just ignore her completely.
Thank you.
