Hopefully they'll stick to it. Most people are generally good about a new task when they first get started, but generally run out of steam as time goes by.
Yeah that is my concern too, especially when the cold and snowy days hit. Not to many people like to go out in those conditions, but it has to be done for the sake of the dog. But I really hope they stick with it, he is not a bad dog, just active.
I am happy that they are adapting to Bailey's needs.
Hopefully they will see how their efforts are paying off in Bailey's behavior and that will encourage them to keep up the routine.
