Many dog breeds have coats with distinctive black and white patterns. Some of the most well-known black and white dog breeds include the Border Collie, Dalmatian, English Springer Spaniel, and Boston Terrier. The black and white coat pattern is caused by the distribution of melanin pigment in the fur. Dogs with piebald coats have irregular patches of white fur lacking melanin mixed with normal color fur.
Common Black and White Dog Breeds
Here are some of the most popular dog breeds with black and white coat patterns:
Border Collie
The Border Collie is an energetic herding dog originally bred to herd sheep in the border region between Scotland and England. Border Collies have a medium length double coat that comes in a variety of colors and patterns. Black and white is a very common color pattern seen in Border Collies. The black and white coat usually consists of a white base color with black patches over the body. The head typically has more black than white coloration. Border Collies are known for their intelligence, trainability and intense herding instinct.
Dalmatian
The Dalmatian is a energetic, loyal breed that was historically used as a carriage dog to accompany and guard horse-drawn coaches. Dalmatians have a short, smooth, densely packed coat that’s always white with distinct round black spots. The spots can vary in size and are randomly distributed over the entire body. Puppies are born with plain white coats and develop their spots as they mature. While black spots are the most common, Dalmatians can also have brown, liver or lemon colored spots. The Dalmatian is known for its unique spotted coat.
English Springer Spaniel
The English Springer Spaniel is a friendly, active gundog used to flush and retrieve birds during hunts. They have a medium-length double coat that comes in liver and white, black and white, black and tan, and other color patterns. The typical black and white Springer has a white background with black patches covering the body and ears. Their coat features feathering on the legs, belly, ears and tail. Springers make excellent family pets with their affectionate nature and enthusiasm for exercise.
Boston Terrier
The Boston Terrier is a lively companion breed originating in Boston, Massachusetts. They are compactly built with a short, smooth, sleek coat. The breed standard allows for a variety of coat colors including black, seal (black with a red cast), and brindle. Boston Terriers with a black and white coat have a base white color with anywhere from a few black patches to a predominantly black coat with white markings. The black and white pattern is very distinctive in this breed. Boston Terriers are known for being sociable, friendly, and full of character.
Other Black and White Dog Breeds
In addition to the most popular breeds mentioned above, there are many other dogs that commonly have black and white coats:
| Breed | Description |

As you can see, many breeds exhibit the classic black and white coat pattern. The breeds listed have short, medium and long coat lengths.
Why Do Dogs Have Black and White Coats?
A dog’s coat color is determined by the pigments eumelanin and pheomelanin. The distribution of these melanin pigments in the fur is controlled by the dog’s genetics. Here’s an explanation of what determines black and white patterning:
– Eumelanin is a dark brown to black pigment. It is responsible for black coat color. White areas lack this pigment.
– The piebald white spotting gene causes irregular white spotting patterns. This piebald gene interrupts eumelanin pigment production in the hair follicles.
– When the piebald gene is present, it results in patches of white fur throughout the coat. Areas with normal pigment levels remain the dog’s base color.
– The amount of white spotting varies considerably among breeds and individual dogs ranging from a few small spots to a predominately white coat.
– The piebald gene can act along with other genes that control the dog’s base color before white spotting is added. This results in breeds with black and white, brown and white, orange and white coats, etc.
Are Black and White Coat Patterns Linked to Health Issues?
Certain canine health issues have been associated with coat color genetics:
– Deafness is more prevalent in dogs with a lot of white coat pigmentation such as Dalmatians. The gene responsible for their white spotting may also affect the cells responsible for inner ear development and hearing.
– Color dilute dogs that carry a variant of the melanophilin gene can suffer from skin issues related to improper pigment distribution. This includes some black and white breeds like Dalmatians and Bull Terriers.
– Autoimmune problems may occur more often in some heavily white spotted breeds. The genes affecting their coat color may also influence immune system development.
– While the piebald genes can increase the likelihood of the above conditions in some breeds, most black and white dogs have normal health and hearing. Extensive white spotting does not guarantee the dog will have these problems.
Popular Black and White Dog Mixes
Crossbreeding dogs with different coat patterns often results in unique black and white puppies. Some popular mixed breeds with black and white coats include:
| Mix | Coat Description |
|---|---|
| Border Collie + Australian Shepherd | Black and white spotted or patched coats. |
| Labrador Retriever + Dalmatian | White coats with black spots. |
| Siberian Husky + Australian Shepherd | Thick black and white double coats. |
| Catahoula + Black Labrador | Black and white abstract splotches. |
| Beagle + Boston Terrier | Black, white and tan coats of various patterns. |
| Bernese Mountain Dog + Poodle | Tri-colored coats with thick black and white patches. |
Crossbreeds tend to have unique coats from the influence of different purebred lineages. The possibilities are endless when it comes to black and white mixed breed dogs.
Conclusion
Many popular dog breeds exhibit signature black and white coat patterns. Patterns range from abstract patches to orderly spots. The distribution of eumelanin and pheomelanin pigment in the fur is determined by the dog’s genetics. While heavy white spotting can increase the risk of certain health issues, most black and white coated dogs are completely normal. Overall, the black and white pattern produces some of the most striking and beautiful dog coats.
