Hi I have a 9 week lab puppy, last week which was his first week with us he was going 11pm to 6am every night with no accidents but for the last 2 nights we have come downstairs to poo and we accidents which are not fresh. He has had the odd accident in the day but not sure how best to proceed at night. We have a baby monitor on him in case he woods or crys but he does not make a sound in to let us know he needs the loo. He sleeps in a crate but the door is not locked and we clean accidents with smell removal spray for dogs so it does not create a habit but not sure how best to proceed he gets lots of praise and treats when he goes outside to toilet but looking for advice as to how to move forward.
