My pup has been doing great with going potty out side. But about 5 days ago he started thid new thing of going potty in his crate at night. But when I leve him in his crate in the day for a longer time span than I do at night he's fine. I 'm trying not feeding him dinner but thats not doing anything. I have beeni going to bed verly late the past week and so he's been out side till I go to bed. Like a few days ago I was out for the day(about 6 hours) and he did just fin. Last night I wnet to bed at about 12:35 right after he was in his crate and than I got up at 5 and he went potty in it. yesterday he did not get fed after hi lunch at 1:30 and he was out side all day. I'm not sure what he's doing. He's even doing it on days when I get up in the night and take him out. some times at night he wont be in his crate for more than 3 hours at a time at night couse I get up and take him out. But he still go's potty. But in the day (after breakfast) he can be in there for 4-6 hours and be just fine.
The last week he has gon potty in his crate every single night.
But he was in hi crate more in the day than at night and he did not do it in the day. HELP!!!

Can some one please help me understand what he's doing so I can make this stop.

Is the crate small enough until he can just stand enough to turn around. The crate has to be small enough so he can't use part of it for the potty.

How old is he? Is the poop firm or loose? Do you know for sure that he is going potty outside before you put him in the crate at night?
You could try taking him for a long walk or playing with him outside to get his bowel moving before you put him in the kennel at night.

His crate is very small, almost too small. But he backs his but up to the door of the crate and than pottys so it lands on my floor and not in his crate. I have seen him do this!
Why dose he not do this in the day? and why did this just start now?

yes-my 2 "piggy"pups will do this too-back their but up to the door-and poop through the wires.
Nasty and really hard to clean(the wires).

The only thing i can tell you is to keep on, and feed them earlier in the afternoon, and no food(minimal treats) after that. For the next 2 weeks, you might have to do some midnight short walks(be safe though) to actually get the pup to potty.

also, i just realized that my pups can hear my alarm from the other side of the house, and if i hit snooze without taking them out-they will go in their crates.

After they wake up, at any point at night-and they stay awake for longer than 5 minutes-they will have to go to the bathroom. As it is now-if i need to potty myself at night, i am sneaking through my house, trying to not wake them up so i dont have to take them out at 3 am in the cold.

Since this is new:

Does the dog have diarrhea?

This is happening for physical reasons, it seems clear, and nothing to do with behavioral issues. The dog has to go and does all he can not to go in the crate.

I'd find out what's wrong. Did mealtime change? Was this after (in addition to) normal daytime poop?

You want to get this fixed now that the dog has done so well.

Would a crate cover help prevent that? I have the portable kind of crate, so my pup can't do that, but maybe this might help:

I think I would want to find out why this is happening. The dog can't make extra poop as a behavioral thing. She has to go, and the time has changed..... so is there diarrhea or a food change? Have the number of poop occasions increased, or only changed times?
