I'm in the process of cage training my sprocker pup ( I said I as it was me who pestered after having a pup, so to stop the moaning I do more than my fair share). At the moment the cage (medium sized) isnt partitioned off and my pup is 11 weeks old, most nights she goes in the cage at 11 after i get in from work, and has been taken out. She goes through the night till 5am mostly without messing although this mornin I got up to a STINKY cage as she was given a treat before we went up, never again. She does go outside most times but accidents happen dont they?... When we take her out we tell her well done after toileting, as we keep good girl for when she has done something like sit and so on.
