Better than not barking and "doing it" in
Rob Roy must bark every day during squirrel watch--doesn't have to see a squirrel, only be watching for one
Ivey barks for no reason at all while laying on her bed and she barks very loud.
Huston barks when he wants to go out or wants a treat (be careful about teaching them to speak--lesson learned )
Austin, in 5 years, has barked maybe 3 times and scared the crap out of me all three times because he was standing fairly close to me, and of course, he doesn't bark
