Just in time for Valentine’s Day, we find furry friends with adorable heart-shaped marks on their bodies. This little piggy, named Valentine, was born with a heart on its back just days before Valentine’s Day. The pig is a Gloucestershire Old Spot, a rare bread specific to western England. Splash News / Newscom Christened “the cutest dog in Japan” in 2007, a long-coated Chihuahua named Heart-kun was born in May 2007 and became an instant celebrity after a local TV station aired his picture. The owner of the shop where Heart-kun was born believes he brought her luck. Issei Kato, Reuters / Landov Meet Love-kun, Heart-kun’s little brother. No, really. This long-coated Chihuahua was born in August 2009 at the same shop as Heart-kun in the tiny northern town of Odate, Japan. Toru Hanai, Reuters / Landov This cute little calf was also born in Japan, and like Heart-kun and Love-kun, she got a spot-inspired name… Heart. The adorable cow was born in late January 2009, just a couple weeks before—you guessed it!—Valentine’s Day.

Wildlife film-maker Sue Flood told The Daily Mail last year that she had never seen such a penguin in 30 trips to the frozen tundra.
