A 4-year-old black Labrador named Zola delivered a mixed 10 pup litter that is rarely seen. A litter like this has only been seen a few times in history.

Zola gave birth to a very rare litter that included a mix of pups in three different colors including pure yellow, chocolate and black.

Zola's owners Martin and Tina Davis have bred labs for many years using Wylanbria Kennels. Over the years, the husband and wife team has discovered how to mix a lab's DNA to produce all three colors of labs from one litter.

Zola's litter produced ten healthy pups. Two yellow, three brown and five black pups. It's almost impossible to find all three colors in one litter of Labradors. But the Davis' have been at it for over 15 years.

Zola's pups were born October 18, 2021, and all have been adopted!
