Drake used to be a braker when there was anyone at the door, yard, etc... He barks and growls when we play. But when we moved to Germany and into an apartment, his barking at the door was unacceptable!!

Luckily, I was at home most of the time, so when I heard someone coming up the stairs, I would run to Drake. Make him sit or lay down. If he barked, I would tell him to stop. Repetition is the key and treats. Now he sits at the door and listens when there is someone walking up the stairs!

Good luck with Moose.
