Lizzie, my retired puppymill breeder, who I have had for three years, has recently begun to wake us up at 4 am to go potty. She usually goes out at night around 10 or 11 pm, and then heads into her crate for bedtime. The crate is something that we had to implement 2 months ago due to her piddling on the floor at my boyfriend's house. I am concerned that she cannot hold her pee for more than 6 hours at night. During the day, she holds it without any issues. She gets a morning walk around 8 am and an afternoon walk at about 5:30, if she wasn't so skiddish the dog walker would also take her out too during the day (she takes out the golden at the house, but Lizzie runs and hides when the dog walker comes over). I know she is a rescue and I'm thankful that she is telling me she has to go outside, but this is now an every evening occurance. I guess I wonder how she can hold it during the day, but at night she doesn't want to hold it. I've tried to take up the water and the food after 8 pm, but she still would want to go out at 4 am. Any thoughts or suggestions?
