Zola the Labrador with her 10 puppies of three colours, HorshamSee SWNS story SWSYpuppy. A Labrador has given birth to an extremely rare mix of pure yellow, chocolate and black puppies in the same litter - in a breeding programme 15 YEARS in the making. Black Labrador Zola, four, delivered ten pups who are a mixture of three different colours - only seen on a 'handful' of occasions before. Owners Tina Davis, 62, and her husband Martin Davis, 63, began breeding with a female chocolate Lab in 2006. Over the years they bred a mixture of yellow, chocolate and black Labs and decided to strategically mix doggy DNA to produce a litter of all three.
