Gunner is 16 weeks. I got him at 13 weeks and he's never once woken me up at night. BUT, I also play hard with him right before bed and wear him out. I also feed him early in the evening so he has his last poop right before bed. Remember your pup is young, and needs a schedule to help get things under control. I definitely would NOT allow her to just pee in the crate. Likely, that will only make you more mad because then you will have a nasty stinky mess to clean up...not to mention it will only slow down housetraining. Although Gunner is great, I've had pups in the past who literally had to go out every 2 hours. It's exhausting yes, but I've also had two human babies so I was used to it. Hang in there...soon she'll grow up a bit and can hold it more.
