If you've never been around a rescue animal, sometimes it takes them time before they let their guard down and feel comfortable around you. That's not a problem for Bunny, a Midwest rescue dog who is completely relaxed as a new video share shows.
A lot of homes have guard dogs. I found one home in the Midwest that doesn't need one. It has a guard duck named Angus and no one passes unless Angus approves and Angus never approves.
