Hi I have a 16 week old chocolate Lab Nelly . Prior to a week ago she was pretty much fully toilet trained but This last week she seems to have gone backwards with it and having a lot more accidents . Is this common ? I’ve stopped rewarding her As much when she goes out with treats A big fuss etc wondering do I need to go back to basics and start again. She’s doing great with training picking things up really quickly , walking great on lead, socialising I still have some issues with sleeping but generally shes settled really well and a joy to have around any advice appreciated x
