Hi - we have a 4 month old cockapoo who is crated at night. Since day 1 he has been absolutely wonderful with dry nights nearly all the time (except from the very early days, and that was only 2 or 3 nights). However, the night before last he fouled all over his bed and puppy pad and last night he wee'd on his puppy pad. I havent done anything differently to make him do this. I have still been taking him out to the toilet just before bed and we are coming down the same time in the morning. Any advice as to why he has just started doing this?
