I always think I can handle animal movies, and I never can. Heart Paws was no exception. If this movie doesn't make you cry I would say it's safe to assume absolutely nothing else will. The focus of Hearty Paws is on emotions, both the characters' and the viewer's. The plot is essentially very simple, the flesh of the movie being how it makes you feel. Yoo Seung Ho as Chan was outshone only by Dolly, the Labrador cast as Hearty. I think it's important to throw out there that training a dog as exceptionally well as Dolly is trained is no easy feat. That aside, Yoo Seung Ho did a phenomenal job as the only (human) character with a substantial role. As a side note, just so there's no confusion, most English translations of this movie refer to Hearty as a "he" but she is in fact a female dog. It's "he" in the gender-neutral way.
