Chihuahua puppy born with love-heart pattern

This chihuahua puppy literally wears its heart on its sleeve.

The cute male pooch, born with a perfect heart-shaped patch on its side, has been suitably named Heartkun by its owner in northern Japan.

The one-and-a-half-month-old pup was born as one of a big litter, but is the only new arrival to sport such a heart-warming coat.

According to owner Emiko Sakurada, this is the first occasion a puppy with such marks had been born out of the more than one thousand chihuahuas she has bred.
