Ruby didn't bark much when he was pup, for the first 5 or 6 months, we thought he can't bark, then he grew.... He was able to reach and look out the window and now he barks at every moving thing outside, let it be people, squirrels, dogs and cats across the street, people walking by, people getting out of their car, and the list goes on.... He also bark when he wants us to play with him.
