Herding Breeds: Black and White Working Dogs

Herding breeds developed their striking black and white coats through centuries of selective breeding in northern Europe. The high contrast pattern was functionally useful – a black and white dog is far easier to spot at distance against moorland or pasture than a fawn or grey dog. The contrast also helped farmers visually separate the dog from the flock being herded.

Border Collie

Scotland/Northern England, 19th century

The quintessential black and white dog. The classic colouration is a black body with white blaze, collar, chest, paws, and tail tip – though the breed comes in over 17 colour combinations. The Border Collie’s black and white appearance is governed by the Irish spotting pattern (s^i allele). Often considered the world’s most intelligent dog breed, they are relentlessly energetic and require a job or intensive training to stay mentally balanced.

Bearded Collie

Scotland, 16th century

The Bearded Collie’s coat is the most deceptive in the herding group – puppies are born black and white but fade dramatically by 18 months, often ending up slate grey and white or fawn and white as adults. True black and white adults are relatively rare in the breed. This coat lightening is caused by the progressive greying gene (G locus), which progressively dilutes eumelanin over the dog’s first two years.

Old English Sheepdog

England, 18th century

The bobtail’s shaggy grey and white coat is one of the most recognisable in the dog world. Like the Bearded Collie, OES are born black and white and fade to blue/grey over time. The profuse double coat – historically used as raw material for spinning wool in England – requires intensive grooming, typically several hours per week to prevent matting. The breed is surprisingly athletic under its cloud-like exterior.

Why Border Collies Are Bred for Intelligence Over Appearance

The Border Collie is unique among herding breeds in that the working dog registry (ISDS – International Sheep Dog Society) does not register by appearance at all – only by working ability. A Border Collie is defined by what it does, not what it looks like. This is why working Border Collies show extreme variation in coat and colour compared to show Border Collies. The famous “eye” – the Border Collie’s intense crouching stare used to psychologically control sheep – was the trait selected for above all others. The black and white coat simply became associated with the breed because it was common in the Scottish Border region where the breed developed, not because it was specifically selected.

Spotted Breeds

Spotted black and white dogs are produced by different genetic mechanisms than the herding breeds above. Where Border Collies carry the Irish spotting allele, the most famous spotted breeds carry piebald or extreme piebald alleles combined with ticking genes that create the characteristic spots.

Dalmatian

Croatia (Dalmatia region), origins disputed

The most recognisable spotted dog in the world. Dalmatians are born completely white – the spots develop over the first three to four weeks of life as melanocytes migrate from the neural crest to the skin. Adult Dalmatians carry 50-200 spots. The spots are caused by the ticking gene (T locus) operating over an extreme white piebald base. No two Dalmatians have identical spot patterns – the distribution is random each time. The breed carries a notable health concern: approximately 30% are born with unilateral deafness and 8% with bilateral deafness, linked to the same genes that cause the white coat.

English Setter

England, 14th-16th century

The English Setter’s distinctive “belton” colouration is one of the most elegant in the sporting group. Blue belton (black and white ticking on a white base) creates a fine salt-and-pepper effect that is entirely different from the bold patching of a piebald breed. The ticking genes produce individual pigmented hairs scattered through white areas rather than concentrated patches. Setters are bred for hunting upland game birds and require substantial daily exercise – they were designed to range miles through heather and bracken.

Harlequin Great Dane

Germany, 16th century

The harlequin Great Dane is one of the most visually dramatic dogs in existence – a pure white base with irregular torn black patches distributed across the body. This pattern requires the simultaneous presence of the merle gene (which cannot be homozygous – double merle causes severe health defects) and a separate modifier gene (H locus) that transforms the grey merle patches into pure white. Breeding harlequins is therefore genetically complex, and responsible breeders must DNA test to avoid producing double merle puppies.

Terrier Group

The terrier group produced several of the most compact, characterful, and distinctive black and white breeds. Terriers were bred for vermin control – a job that required courage, independence, and tenacity rather than biddability. These traits remain strong in the modern terrier, making them entertaining but sometimes challenging companions.

Boston Terrier

United States, 1870s

The Boston Terrier’s tuxedo colouration is one of the most formally precise of all dog breeds – the breed standard requires white on the muzzle, between the eyes, forechest, and forelegs, with the balance of the dog being black, brindle, or seal (a very dark brown that appears black). The Boston is one of only a handful of breeds developed entirely in the United States, and the breed’s formal markings led to the nickname “The American Gentleman.” Despite the terrier name, Bostons are non-aggressive companion dogs – they were bred down from fighting dogs but the fighting instinct was bred out over generations.

Bull Terrier

England, 1830s

The white Bull Terrier is so associated with the colour that it is often thought of as an entirely white breed, but the breed occurs in coloured varieties (brindle and white, black and white, red and white) as well. The pure white variant carries the extreme piebald gene (s^w). The white colouration is linked to deafness risk – white Bull Terriers should have a BAER (Brainstem Auditory Evoked Response) hearing test before leaving the breeder. The breed’s distinctive egg-shaped head with the downward Roman nose is unlike any other breed in the world.

Jack Russell Terrier

England, 19th century

The Jack Russell Terrier is predominantly white by design. The Reverend John Russell, who developed the breed in the 1800s for fox hunting, specifically selected for a mostly white dog so it could be distinguished from the fox underground and would not be struck by accident by huntsmen. The white body with tan, black, or brown patches on the head and base of tail remains the classic colouration. The breed standard requires more than 51% white. Jack Russells are disproportionately brave, quick, and vocal for their size.

Working Breeds

Siberian Husky

Siberia, ancient breed

The Siberian Husky’s black and white colouring is one of its five accepted colour combinations – others include grey and white, red and white, agouti and white, and pure white. The black and white Husky typically has a black saddle-like marking over the back and shoulders with white on the face, chest, and legs. The breed’s double coat – a dense undercoat and longer guard hairs – provides insulation in temperatures as low as -60°C. The distinctive face mask markings are unique to each individual dog, much like a fingerprint.

Bernese Mountain Dog

Switzerland, ancient farm dog

The Bernese Mountain Dog is technically a tricolour rather than a bicolour – the required pattern is jet black with clear white and rust markings. The breed standard mandates a white blaze on the face, white chest cross (the iconic “Swiss cross”), and white paws, with rust points above the eyes, on the cheeks, and on the legs. The Bernese was developed as a draft animal and farm dog in the Swiss Alps – males could pull carts ten times their own body weight. The breed’s lifespan is unfortunately short (7-10 years) due to high cancer rates.

Companion Breeds

French Bulldog (b&w)

France/England, 19th century

The black and white French Bulldog carries the piebald gene (s^p) and appears as a white dog with large black patches, or a black dog with white patches, depending on how much piebald coverage the individual carries. The breed’s compact, muscular body, bat ears, and flat face have made it one of the most popular dogs in the world, though its extreme brachycephalic anatomy creates documented breathing difficulties. Black and white Frenchies are not rare – the colour combination is common in the breed.

Papillon

France/Belgium, 16th century

The Papillon (French for butterfly) takes its name from its fringed upright ears that resemble butterfly wings. The breed is always parti-coloured (white with patches of another colour), and black and white is one of its most striking combinations. The white blaze down the centre of the face is characteristic of the breed, with colour on the ears and body. Despite its tiny size (3-5 kg), the Papillon is an exceptionally active, intelligent, and athletic dog – it consistently places among the top three breeds in obedience competitions.

Shih Tzu (b&w)

Tibet/China, ancient breed

While the Shih Tzu comes in a wide range of colours, black and white is one of its most popular show and pet colour combinations. The flowing double coat, which can reach the ground when uncut, requires daily grooming or professional maintenance in a “puppy cut.” The breed was developed as a palace companion for Chinese royalty and was considered sacred – they were not traded, sold, or given away for centuries. The breed’s flat face creates the same brachycephalic breathing concerns as the French Bulldog and Boston Terrier.

Genetics of Black and White Coats

Black and white colouration in dogs is controlled by a relatively small number of gene loci, each operating independently. Understanding the basic genetics helps explain why two black and white Border Collies can look dramatically different from each other, and why crossing two black and white dogs does not always produce black and white puppies.

Gene Locus What It Controls Key Alleles Effect in B&W Dogs
E locus (Extension) Whether eumelanin (dark pigment) can be expressed at all E (allows colour), e (blocks it) Dogs must carry at least one E to show any black pigment
B locus (Brown) Black vs brown eumelanin production B (black), b (brown) True black requires BB or Bb; bb produces liver/chocolate
A locus (Agouti) Pattern of eumelanin and phaeomelanin across the body a^y a^w a^t a a (recessive black) produces solid black; a^t adds tan points
S locus (Spotting) How much white coverage the dog carries S s^i s^p s^w Controls where and how much white appears; see coat pattern chart above
M locus (Merle) Random dilution of eumelanin creating a mottled pattern M (merle), m (non-merle) Mm = merle; MM = double merle (health defects including blindness and deafness)
T locus (Ticking) Whether coloured flecks appear in white areas T (ticked), t (clear) Creates the speckled belton pattern in Setters; spotted Dalmatian pattern

Why White Coats Are Linked to Deafness

The link between extreme white colouration and deafness in dogs (and cats) is one of the most well-understood examples of a pleiotropic gene – a gene that has multiple biological effects. The s^w (extreme piebald) and M locus (merle) alleles that create extensive white coat coverage work by reducing or eliminating melanocytes – the pigment-producing cells that migrate from the neural crest during embryonic development. Melanocytes are not only responsible for coat colour: they are also essential for the proper development of the stria vascularis, a structure in the cochlea (inner ear) that is required for hearing. When the gene reduces melanocyte migration too severely, the stria vascularis fails to develop, and the result is irreversible congenital deafness. Dogs with two copies of the extreme white alleles (homozygous) are at the highest risk. This is why Dalmatians, white Bull Terriers, and white Boxers should be BAER tested before placement.

Care Considerations Specific to Black and White Dogs

Sun Sensitivity

White fur provides no UV protection. Dogs with large white areas – especially on the nose, ears, and around the eyes – are at significantly elevated risk of solar-induced skin damage compared to darker-coated dogs. Pink-skinned white dogs exposed to sustained sunlight can develop actinic keratosis (pre-cancerous lesions) and squamous cell carcinoma on exposed white-furred areas, particularly the nose and ear tips. In warm climates or during summer months, pet-safe sunscreen (avoid human sunscreen containing zinc oxide, which is toxic to dogs) on exposed pink areas is advisable.

Tear Staining on White Areas

Black and white dogs with white facial markings – particularly Boston Terriers, Shih Tzus, Papillons, and brachycephalic breeds – often develop rust-brown tear staining beneath the eyes. The staining is caused by porphyrins: iron-containing compounds in tears and saliva that oxidise to a brownish-red colour on white fur. Daily cleaning with a damp cloth reduces staining. Persistent staining may indicate blocked tear ducts, entropion (inward-rolling eyelids), or allergies that cause excessive tearing – all warrant veterinary investigation.

Grooming the Black and White Coat

Black and white coats present the grooming challenge of showing both dirt and white hairs simultaneously. Black areas show dust, white hairs, and sebaceous secretions clearly. White areas show any mud or biological staining immediately. Breeds with both colours in large sections (Bernese Mountain Dogs, Huskies) require regular brushing to manage shedding of both colours. On tiled or hardwood floors, black hairs from a white-dominated dog can be particularly visible – and vice versa. Frequent vacuuming and the use of contrast-appropriate soft furnishings is a practical consideration for black and white dog ownership.

Frequently Asked Questions

What is the most common black and white dog breed?
The Border Collie is the most numerous and widely recognised black and white dog breed globally. Dalmatians and Boston Terriers are also extremely common in their respective contexts (family pets and companion dogs respectively). Among large breeds, the Siberian Husky (black and white variant) and Bernese Mountain Dog are among the most popular black-dominant or black-and-white working breeds registered each year in the UK and US.
Are Dalmatians born with spots?
No – Dalmatians are born completely white. Their spots begin to emerge at two to three weeks of age as melanocytes migrate to the skin and begin producing pigment. By six to eight weeks old, a puppy’s spot pattern is largely established, though the spots may continue to develop slightly through the first year. No two Dalmatians have the same spot pattern – the distribution is entirely random, governed by the stochastic nature of melanocyte migration during embryonic development.
Why are some black and white dogs prone to deafness?
The gene variants that create extensive white colouration (particularly the extreme piebald s^w allele and the merle M allele) also reduce the number of melanocytes that migrate to the inner ear during embryonic development. Melanocytes are needed to form the stria vascularis in the cochlea – a structure essential for hearing. When this structure fails to develop, the result is permanent congenital deafness. Breeds at highest risk include Dalmatians, white Bull Terriers, white Boxers, and double merle dogs of any breed. BAER (Brainstem Auditory Evoked Response) testing is the standard diagnostic tool.
Do black and white puppies stay the same colour as they age?
Not always. Several breeds that appear black and white as puppies change dramatically with age. Bearded Collies, Old English Sheepdogs, and Kerry Blue Terriers all carry a progressive greying gene (G locus) that dilutes black pigment over the first 18-24 months of life, producing adult dogs that are grey and white rather than black and white. Conversely, some breeds darken slightly as adults. For breeds like the Border Collie, the basic black and white pattern remains stable throughout life, though ageing dogs may develop some greying around the muzzle.
