What breed of dog is spotted?

Spotted dogs come in many different breeds. The spots can range from large splotches to small dots, and the coat colors can vary widely. Some of the most common spotted dog breeds include Dalmatians, English Setters, Australian Cattle Dogs, Great Danes, Beagles, Chihuahuas, Dachshunds, and Catahoula Leopard Dogs. The spots are caused by a genetic mutation that affects pigment distribution in the coat. While some breeds are defined by their spots, in other breeds the spots are random. Let’s take a closer look at some of the most popular spotted dog breeds.


The Dalmatian is likely the most well-known spotted breed. Dalmatians have a distinctive white coat with black or liver-colored spots. The spots usually range in size from dime-sized to large blotches. Dalmatians are energetic, playful, and loyal. They were originally bred to run alongside carriages and guard the horses and passengers. Today they make lively family pets and working dogs. Dalmatians need a lot of exercise and mental stimulation. Without enough activity they can become destructive or high-strung. Dalmatians shed year-round and are not recommended for allergy sufferers.

English Setter

The elegant English Setter has a white background coat with large patches of black, liver, orange, lemon, or blue belton spots. The spots make the English Setter’s coat very striking and unique. English Setters are energetic gun dogs bred for hunting upland game birds. Despite their energy in the field, they are gentle and sweet at home. English Setters do best with active families who can give them daily outdoor exercise. Their long, silky coat requires frequent brushing to prevent mats and tangles.

Australian Cattle Dog

The Australian Cattle Dog, also called a Blue Heeler or Queensland Heeler, is a rugged herding breed from Australia. They have a distinctive mottled coat pattern with black and white hair mingled with tan spots. Sometimes red speckles are also present in the predominantly blue coat. The coloration helps camouflage the dogs as they work with cattle. Australian Cattle Dogs are extremely energetic, intelligent, and driven. They need a job to do and ample daily exercise. Without enough activity they can become destructive or neurotic. Their weatherproof coat requires minimal grooming.

Great Dane

Great Danes are giant dogs that often display spotting in their short, smooth coat. The base coat color can be blue, black, fawn, brindle, mantle or harlequin. Random spots appear in the base color as black or liver-colored patches. The harlequin pattern features large black patches over a white background. Great Danes are regal, loyal family companions despite their imposing size. They need moderate daily exercise and dedicated training. Great Danes are prone to numerous health issues due to their rapid growth and gigantic size. Lifespan is sadly shorter than many breeds.


Beagles are small hunting hounds recognized by their tricolor coats of black, tan and white. The black blanket-like spots are intermingled with smaller tan dots. Beagles are compact, curious, and energetic. Their determination to follow scents makes them great hunting dogs but also challenging pets without secure fences. Beagles bark and howl frequently. They require daily exercise and mental stimulation. Grooming is easy thanks to the short, dense coat that sheds moderately year-round.


Chihuahuas are tiny dogs that come in virtually any color or pattern, including different spotting variations. Black, tan, chocolate, or fawn coats can all feature various colored spots. The spots can range from small dots to large patches. Chihuahuas are feisty, bold little dogs devoted to their people. They can be wary of strangers and children. Early socialization is essential. Chihuahuas don’t need much exercise but love interaction with their favorite humans. Their tiny size makes them fragile, so they are best suited to adult-only homes.


Dachshunds are long, low dogs bred to hunt badgers and other burrow-dwelling animals. They come in three coat varieties: smooth, longhaired, and wirehaired. All coat types can display spots over color combinations that include chocolate, black, and red. Spots are more common on piebald Dachshunds that have large white areas breaking up the base color. Dachshunds are energetic, curious, and often stubborn. They will follow their nose on the hunt without heeding commands. Early training is recommended. Regular exercise is a must to prevent obesity and back problems.

Catahoula Leopard Dog

As their name suggests, Catahoula Leopard Dogs feature a distinctive leopard-like coat with patches called leopard spots. These spots can be brown, black, gray, or red over a white coat. No two Catahoulas have the exact same spotting pattern. Catahoulas were bred to herd hogs and cattle in Louisiana’s swamplands. They are assertive, energetic working dogs that need a job and open space to roam. Lots of exercise is required daily. Without it, Catahoulas can become bored and destructive. An experienced owner is best for this intense breed.

Other Spotted Breeds

In addition to the breeds already mentioned, many other dogs can display spots in their coat. These include:

  • Boxers – Fawn coat with black mask and white spots
  • Collies – Black, tan, and white spots
  • Corgis – Red, white, black, and tan spots
  • American Staffordshire Terriers – Brindle coat with white spots
  • Boston Terriers – Black and white coat
  • Pointers – Liver, black, lemon, or orange spots
  • Spaniels – Black, liver, orange, or lemon spots

What Causes Spots in Dogs?

The spots that appear in certain dog breeds are caused by a genetic mutation that affects melanin pigment distribution in the coat. Melanin occurs in two forms: eumelanin which produces black/brown pigment, and phaeomelanin which produces red/yellow pigment. The mutation causes the melanocytes (pigment producing cells) to activate and produce pigment in a spotted pattern rather than an even distribution.

In breeds like Dalmatians where the spots are a defining characteristic, selective breeding over many generations has maintained and propagated this spotting mutation. For other breeds, the spots are random and not necessarily selected for in breeding programs.

The exact genetic mechanism behind the dog spotting pattern is not fully understood. However, research suggests that the mutation causing spots disrupts the interaction between genes involved in pigment production and those that guide pigment cell migration during skin development. This results in clumps of pigment rather than a smooth, uniform distribution.

Spotted Patterns and Terminology

There are various terms used to describe the different spotting patterns seen in dogs:

Term Description
Ticking Small dot-like spots distributed throughout a solid background color
Speckles or Flecks Small spotting similar to ticking but more random
Roan Mixture of white and colored hairs blended together
Brindle Tiger-like stripes rather than spots
Leopard Large irregular spotting pattern similar to a leopard’s
Piebald Large white patches breaking up a colored background
Merle Marbled coat with darker blotches on a lighter background
Abstract Sparse, irregular spotting with no distinct pattern

Health Considerations

For the most part, the spotting pattern itself does not directly impact the health of dogs. However, some spotted breeds are prone to certain conditions. Dalmatians can suffer from urinary stones, congenital deafness, and allergies. Great Danes and other extra large breeds are at risk for bone cancer, hypothyroidism, cardiomyopathy, and bloat. Beagles commonly deal with obesity, epilepsy, cherry eye, and spinal conditions. Getting dogs from reputable breeders and maintaining routine vet care is important for any breed.


Spotted coats add striking beauty and visual appeal to many dog breeds. While the spots are a defining feature for some breeds like Dalmatians and Australian Cattle Dogs, they appear randomly in others. Genetic mutations affecting pigment cells during skin development are behind the patterning. Spotted breeds span a range of sizes, energy levels, and purposes from loyal Dalmatian family dogs to intense working Catahoula Leopard Dogs. No matter their differences, all spotted dogs bring joy and companionship to life.
