Meet Heart-kun, a Chihuahua that was born with a perfect heart-shape birthmark.
The puppy was born in May to breeder Emiko Sakurada in Odate, northern Japan. Emiko said that she had never seen a similar mark on the 1000 puppies she had bred; she doesn’t plan to sell this special puppy.
[August 2009 update] Guess what? Heart-kun has a brother with identical mark.
