Puppy pooping and peeing in crate only at night
I have a 10 week Papillon that I have been trying to potty train. I have had success with my 2 year old Maltese, but struggling with my new puppy. I have chosen to train him on a pad. He is only in the crate for a short period, if I am not able to keep watch of him. Otherwise he is always with me, since I am home. During the day he does very well, but he is also very stubborn. Sometimes it takes 45 minutes or more for him to finally do something on the pad. But overall during the day he's doing pretty good considering his age.
My problem is in the evening. His last feeding is usually around 6:30pm. About 15 minutes after dinner, I take him to his pad and he does his business. Then before I call it a night, I'll take him to the pad once again. His crate is in my room and he seems to like his crate because he tends to go in there on his own during the day. But at night he makes me believe he's sleeping through the night, because he doesn't make a sound. Yet when morning comes, he has peed and pooped in the crate.
I don't know what to do, since he doesn't even whimper giving me notice that he needs to go. He did the first few days he was with us, but not anymore. Weird thing, that during the day he will whimper for me.
Could it be the crate is too big? I just don't know what to do, to break this evening habit. Any suggestions would be greatly appreciated.
