When people hear about blue dog breeds, they often imagine a vibrant navy blue pup, but in reality, blue coated dogs have a stunning silvery gray or bluish coloration that looks absolutely magical.
Studies show that when homozygous with a dilution gene, a black dog becomes blue. This same gene also impacts the nose and eye colors—blue dogs will have a blue-pigmented nose. Their eyes often lighten beautifully to amber.
The fascinating part is that many different breeds can carry this diluted gene—even dogs that are born black might surprise you with a beautiful blue coat. It’s an accepted color in some breed standards, while in other breeds, it’s more of a rare, unique appearance. Either way, these pups are always showstoppers, whether they have white markings, black patches, or just solid colors in soft silvery gray.
Ready to meet some of the most popular breeds that flaunt this rare coat color? Let’s take a look at some stunning blue dogs with their one-of-a-kind charm!
Dog Breeds With Blue Coats
1. Australian Cattle Dog
Also known as the Red Heeler or Blue Heeler, the Australian Cattle Dog is one of the most iconic blue dog breeds. This hardworking herding dog has a beautiful blue coat that can be solid, speckled, or mottled. You’ll often see touches of tan or black markings on their head and body, but the overall look is always a cool, blue cast.
Because of their loyal nature, these pups are sometimes called “shadow dogs” since they love to stay close to their humans. They do best in homes where they can have a job to do, whether it’s herding, agility sports, or even joining you on long runs and hikes.
While they can show black patches or tan points, their unique coat colour remains predominantly blue. Blue Heelers often have a black mask over one or both eyes, adding to their striking, unique appearance.
With the right proper training and socialization, they make great pets for experienced owners who appreciate their hardworking spirit.
2. Kerry Blue Terrier
As the name suggests, the Kerry Blue Terrier is a blue dog breed that comes in only one color—blue! Their unique, wavy coat can range from a deep slate tone to a soft, silvery blue-gray.
While the head, muzzle, ears, tail, and feet are often darker—sometimes even black—the breed standard requires the signature blue coat to be clearly visible.
AKC states that all Kerry Blue Terrier puppies are born with a black coat. Through a process called clearing, their fur gradually lightens over time, turning into the beautiful blue coat they’re known for. It usually takes about 18 months for their full adult coat color to develop.
This Irish breed is elegant yet sturdy. With its long legs, muscular frame, and charming bearded face, it has that classic Terrier look. Their dense, soft, and curly fur doesn’t shed naturally, so regular brushing and grooming are needed to prevent tangles and mats.
3. Weimaraner
The blue Weimaraner is a striking variation of this elegant hunting dog. Most Weimaraners are known for their steely gray coat, but when a black dilute gene appears, it produces a beautiful dark-blue shade.
While the color is captivating, the blue Weimaraner is not a recognized breed standard for dog shows, meaning they can’t compete in official conformation events.
Despite that, many people love their sleek and velvety look. Their fur is usually solid and smooth without complex coat patterns like blue merle, blue brindle, or blue tick. Instead, the charm lies in the even, glossy coloring that makes them stand out.
Historically, Weimaraners were bred as hunting dogs, and their loyal, alert nature makes them good guard dogs as well as affectionate companions. Even though the blue Weimaraner isn’t a common sight, it’s easy to see why so many people are drawn to their graceful, athletic build and unique blue-toned coat.
4. Chihuahua
The tiny Chihuahua may surprise you as part of the blue dog breeds list. While many think of them in classic tan or cream color, some are born with a rare blue coat. This color can appear as a soft silvery gray or a deeper blue gray that gives these little dogs an unexpected, elegant twist.
According to the breed standard, solid colors are accepted, and a solid blue coat—while rare—is a true head-turner. Sometimes, you may see coat patterns like blue merle or even small white markings mixed into their fur, but a pure blue color is the most desired.
Despite their tiny size, Chihuahuas have a bold personality and a strong protective nature. They are alert, devoted, and often act like guard dogs in their own way, warning their owners of any strangers.
When paired with proper training, these little dogs can be loyal companions and great pets for those who appreciate their spunky and (sometimes) stubborn attitude.
5. Bearded Collie
The Bearded Collie is a shaggy herding dog with a coat that comes in various shades, including a lovely blue. Often, you’ll see soft gray shades across their body with lighter areas that create gentle blue-gray shading. Puppies are usually born with a darker coat, which gradually lightens as they mature.
These dogs often have white on the face, chest, legs, and tail, while the body stays more solid in color from the shoulders back. Despite the changing coat, they have always had a black nose, which stands out against their fluffy fur.
Bearded Collies are social, friendly, and love being around people and other pets. As herding dogs, they have plenty of energy and need both regular exercise and plenty of mental stimulation to stay happy. Their lively personality and beautiful coat make them wonderful companions for active families.
6. Italian Greyhound
The elegant Italian Greyhound is a graceful, miniature version of the classic Greyhound, known for its slender build and silky coat. PetMD mentions that, as the smallest sighthounds, Italian Greyhounds stand only 13–15 inches tall, making them both dainty and athletic.
Among their many soft hues, some have a gorgeous blue tone that can look like deeper charcoal in certain lighting. Their fine, delicate feet often feature grey paw pads that match their sleek appearance.
Italian Greyhounds are known for their gentle and affectionate nature. They form strong bonds with their families and love to snuggle, but they’re also playful and full of energy when it’s time for fun.
While they enjoy lounging like royalty, they still need regular physical exercise to stay healthy and happy. Short sprints or playful bursts of energy are often enough to satisfy them.
One quirky and unique trait is their tendency to suddenly run at full speed and then abruptly dart in the opposite direction—a playful behavior that highlights their agility and lightning-fast reflexes. This makes them fun to watch and an endless source of amusement for their owners.
7. Blue Lacy
The Blue Lacy is a rare working dog that has a special place in history as the official Texas state dog. Originally developed by the Lacy brothers in the mid-1800s, this hardworking lacy dog was bred to help ranchers with herding and other tough tasks. Unlike a common breed, the Blue Lacy is still relatively unknown outside Texas, making it a unique find for dog lovers.
This dog carries a recessive gene that creates its striking blue coat. Along with its short, easy-to-maintain fur, the Blue Lacy often has a soft grey nose that adds to its sleek look. Although they can also produce red, cream, or tricolor puppies, the classic blue coat remains the most iconic.
Energetic and highly intelligent, the Blue Lacy thrives when it has a job to do. It bonds closely with its family and excels in active homes where it can put its natural skills to work.
8. Neapolitan Mastiff
The Neapolitan Mastiff is an impressive guardian breed known for its massive size and protective nature. Though not a common breed for blue coats, some Neos have a striking bluish tone to their fur that makes them stand out. Their large, wrinkled faces are framed by loose skin, giving them a truly unforgettable look.
Despite their tough appearance, these dogs are calm and devoted to their families. Their quiet confidence makes them good guard dogs, offering both companionship and security. Neapolitan Mastiffs often have a broad head with a soft, grey nose that blends perfectly with their unique coat.
While they might look intimidating, these gentle giants are affectionate and loyal when raised with proper training. Their protective nature and powerful build make them excellent companions for experienced owners who can handle their size and strength.
9. American Staffordshire Terrier
The American Staffordshire Terrier is a confident and muscular dog with a big heart. Often admired for its sleek, short coat, this breed can sometimes display a striking blue shade that makes it stand out among blue dog breeds.
While many have solid colors, some show unique coat patterns like subtle blue brindle, giving them an extra touch of charm.
AKC says that owners describe these dogs as keenly aware of their surroundings, game for anything, and lovable ‘personality dogs’ around the house. They’re energetic, alert, and love being involved in family activities. With their strong build and fearless spirit, they also have a natural protective nature, making them reliable companions when given proper training.
Despite their tough appearance, American Staffordshire Terriers are affectionate and deeply loyal. They thrive on attention and enjoy bonding with their families. A well-socialized AmStaff can be both a playful friend and a trustworthy guardian, proving why they remain one of the most popular breeds.
