A teeny weeny pee problem

For the last couple of months, it's been like having a newborn baby in the house. Our cute blonde Rebba girl is having a pee problem. It's like her bladder has shrunk somehow. She needs to pee all the time. During the day and at night. The daytime pees are not that much of a hazard. It's the nighttime pee sessions that drive us crazy. We don't go to bed that early. But Rebba cannot spend more than 4 - 5 hours without setting her bladder free. We have tried so many things but so far, nothing seems to help. Meaning we have to get up around 3:00 AM or 4:00 AM to let her go outside and do her thing. The interrupted nights are taking their toll. We are exhausted.. Rebba has no idea and she's always real happy to see us. No time to cuddle though, because she has to stretch her legs real fast and run for the back door, so she can do what she has to do. After that midnight call, the dogs have no intention to go back into their bench to sleep. So they spend the rest of the night snoring on the couch. If you happen to be a dog whisperer or if you have other ideas to help us solve this issue, feel free to let us know. We are at the end of our rope..
