My goodness do we love dogs. They're loyal, always adorable, playful, and sometimes just plain wacky. Dogs are capable of so many awesome tricks and their instinctive nature is always mesmerizing. If you work really hard at training a dog, chances are they can accomplish more than we realize -- even communicating! Dogs who herd are not only trained but they have the instinct to do so naturally. Even if they don't technically have sheep to herd...like Arwen, for example.
Tumblr user, gallusrostromegalu, revealed the story of how his dog, Arwen, decided to herd a lawn Roomba. Strap on those seatbelts, folks, we're in for a fun ride!
