My 5.month old has his last.meal.about half 4pm he goes on a walk around 6 or 7. He's always dropping off and there's no stopping him when he's back. I tale him out alot before bed to.do.his business but he poos around 5 half 5 then he won't do another one before bed which we I about half 9. Last night I was out for about an hour trying to make him have a poo before bed but nothing.he woke me up at 2 am but not to say he needed one but to say he had already done one?? 1. Why is he not barking to be let out but when it's too late and 2. Why is he still wetting and pooing his bed??? Some nights he's okay.
