My puppy is 4 months now and his nighttime sleep patterns seem to have gotten worse.
He consistently wakes up between 3:30 and 4:30 every night and then doesn't want to go back to sleep. Sometimes he has to go out and poop, but a lot time not. When he was younger, he slept from 11 to 5:30 or 6. Not sure why his pattern has changed. If i stay in the room with him, sometime he will sleep for another hour and if i feed him at 5, he might sleep for another hour or so. I don't have the crate in our bedroom as during the day that wouldn't work.
We did switch from ScienceDiet Puppy to ProPlan Puppy. Not sure if that impacted him.
Any ideas? I am considering a "whine it out" at some point and see if it breaks the pattern.
