A PUPPY has been born in Japan with a large, clear, love-heart-shaped pattern in his coat. The Chihuahua was born in May as one of a litter to a breeder. Shop owner Emiko Sakurada said it was the first time a puppy with the marks had been born out of a thousand she had bred. She had no plans to sell the puppy, which has been named 'Heart-kun'. The long-coated male Chihuahua puppy was born in Odate, northern Japan
