This is the adorable chihuahua puppy who, like his older brother, was born with a perfect heart-shaped patch on his side.
The cute little pooch has been suitably named Lovekun by its owner in northern Japan.
At three days old, the long-haired chihuahua has been catching up on his sleep between bouts of suckling on his mother with the other three pups in the litter.

But he was the only one in the batch to get the distinctive heart-shaped marking.
His older brother Heartkun was born to the same mother two years ago - and now has some stiff competition in the cuteness stakes.
Today the pair had their photographs taken at Pucchin Dog's shop in Odate, northern Japan.

Lovekun was feeling very sleepy and dozed on the sofa while an excitably Heartkun proved the consummate professional and happily posed for the camera.
When Heartkun was born, his owner Emiko Sakurada said at the time it was the first occasion a puppy with such marks had been born out of the more than one thousand chihuahuas she has bred.
