A few weeks ago we got a Jack Russell rescue dog ( why anyone would abandon a beaut like this guy I don't know! ). The vet thinks he is around a year old ( I think he may be more like 8 to 9 mths old, but what do I know! ). He has been great and learns at a very fast pace. We've had to re-potty train and he has done great. Even learning the "go potty" command in this little time. My question is about our middle of the night bathroom breaks. We are crate training at night so he will whine to go out once or on occasion twice a night so far. By taking him out are we setting up a schedule in his head or do you think eventually when older he will start holding his need for the night?
