Adorable pics show small Great Dane become a towering giant

My, how quickly they grow up. Or in the case of big dog breeds, how quickly they become gigantic creatures capable of plowing you over in one playful jump. Meet case in point Kira, an adorable Great Dane whose then-and-now pic comparison of her at 4 months and 10 months offers an astonishing visual example of how fast a pup can get big. Like other adorable past-and-present pet pics, this side-by-side image has gone viral. It's hard to believe the cuddly pup on the left in mom's arms is the same oversized animal towering over her in the one on the right (at 5 feet, 7 inches, no less). OK, so if this is Kira at 10 months, does that mean at a full year she'll be a full-on horse? [Source]
