Whats with all these evening eating poodles?! Annie is the same by preference. When we are alone, she snacks maybe a bit in the morning, maybe not, eats a bit of kibble at lunch, snacks a bit at dinner time, then chows down at 8 or 9 pm.
I wouldn't worry it too much, dogs are adaptable to most schedules.
Annie used to be a 10:30 am or 11 am pee-er, lazing in my bed without stirring as I had a bath until I got dressed, but when my schedule changed when I moved back with my mom she adapted within a few days, and now expects to go out at 6:30-7:30 am(and needs to go). She also coincidentally discovered my mother feeds the other dog at that time, including extra chicken on top, and is willing to feed early-rising poodles chicken too. This is with the same evening last pee time of 10:30 or 11 pm.
Humans are the same. I used to work 12 hour work days on remote construction sites, no bathroom for kilometers other than a gross portapotty shared with all men (maybe) or a bush (in full view of the men I worked with- no thanks!), or a snowbank. The first two days were hard and I might find a bush, then after that I would adapt to holding it all day without issues unless I guzzled coffee. I suspect there are hormones involved with regulating and preparing thirst/desire to urinate signals, and, like sleep/hunger hormones, they adapt to your schedule fairly readily (assuming no other underlying health issues).
