He has only just recently started doing this. It seems to be first thing in the morning and as it is we are getting up to let them out at 5am! He hops up on the lounge to go to the toiler. He used to never go to the toiler during the night, but has picked up this behaviour, the lounge is brand new! There has been no change in his diet lately either. The other dog doesnt make any mess inside. He is a little dog. They are getting disturbed by the other dogs in other parts of the house. How do I stop him pooping inside and on the lounge?
