Bodie doesn't bark at trash cans but let a vacuum be sitting somewhere(not on), and he will start pouncing at it and barking and he'll jump at it but never actually touch it! And when the vacuum barks back, it's on!! If the vacuum barks and lunges toward him, he runs as fast as his short legs can, away from it! But then he pounces back at it barking again!! (He seems to have no clue that its me barking, actually thinks the vacuum barks!!)
If the vacuum is on, he does nothing!!! Crazy bulldog!!
