Two nights ago I brought in a foster dog. He's older but I was told he was house trained and had been kept in a crate at some point in his life and that he was used to it.
I have two other dogs that I want to slowly introduce him to, so when they are out he is in the crate (as well as at night).
So far he has wet the crate every time I put him in it. Regardless of if I have JUST taken him out and he goes. One time I let him go to the bathroom outside, I put him in the crate and checked on him after half an hour and he had peed.
I'm not sure if the crate is too large or what reason he is doing this.
Oh, and put half of an overnight maxi pad in the belly band. I don't know the breed of this dog, but this will absorb the entire bladder of pee of a dog up to about 30 pounds. Use a whole one if he is larger.
