This is ALL very interesting I am looking at adopting shortly and am keen to find out what others think is best practice as I will be at work ALL day and want to make sure puppy is ok at home by himself ALLDAY. We have 2 cats so I am thinking it might be safer to lock puppy in a room away from them. It's all very confusing with toileting - belly bands, training pads and going outside - enough to confuse any puppy - let alone the owner!
