This adorable Chihuahua pup was born with a perfect heart-shaped patch on his side — just like his older brother.
The cute youngster — named Lovekun by its owner — was born in a litter of four this week.
Brotherly love ... Lovekun with older sibling Heartkun
But Lovekun was the only pooch born with the distinctive heart marking — just as his older brother Heartkun was two years ago.
The cuddly pair posed for photos today at a pet shop in Odate, northern Japan.
Thrilled owner and breeder Emiko Sakurada said they were the only two puppies born with the marking out of the thousands she has bred.
