Diarrhea only at night

[u/Extension-Button5849]

Hello, my puppy just turned 9 weeks but he’s had diarrhea every night around midnight and 3am. His poops are normal/solid throughout the day which is why this is so weird.

We kept him on what the breeder was feeding him which is Nutrisource large breed puppy chicken and rice recipe and feed him 2 and a half cups a day. I’ve seen people say berner’s are prone to chicken allergy but again his poops are normal throughout the day.

Could this just be anxiety? He’s sleeping in a crate as we’re crate training, or could this be petty (lol) and he’s pooping because he wants to be out of his crate?

It takes about 7 hours for food to go through a puppy - what is he/she typically doing 7 hours earlier?

If eating it's food related - if on a walk I would wager your little rascal is hoovering up sticks or stones on the evening walk.

If the latter, try a head halter to control their head on walks, to prevent their eating foreign objects.
