1. Bull Terrier or Bulldog
The Bull Terrier is a breed that originated from ancient Asian mastiffs but truly developed in England. Initially bred for brutal bull-baiting matches, they later became popular as guard dogs. Recognized by several universities and organizations in both the UK and the US, today, Bull Terriers are highly sought after due to their appearance and temperament. They tend to be overeaters and can be quite lazy, often leading to obesity. They are also among the most expensive dog breeds, with prices ranging from $2,500 to $9,000 each. This breed has a long and rich history. The name 'Bulldog' comes from their robust and muscular build, resembling a bull's strength, which made them formidable opponents in fights with bulls during the bloodsport days. These brutal matches were banned in the 19th century, and since then, the breed has undergone significant changes, particularly throughout the 1800s when standard dog shows began.
Initially, Bulldogs were used in bull-baiting competitions. They had longer legs compared to their descendants today. In 1835, when bull-baiting was banned in the UK, Bulldogs were introduced to dog fighting but were soon overshadowed by the Bull Terrier, which was more compact and easier to hide during illegal dog fights. As a result, Bulldogs became less popular. However, the breed experienced a resurgence as a pet, becoming a widely loved companion. Bulldogs played an important role in the creation of new breeds through selective breeding, such as the Bully and Bull Terrier. Bulldogs are short-legged, with a distinctive wrinkled face and often sticking out their tongues. Despite their tough and somewhat intimidating appearance, they are affectionate, courageous, and easy to groom. Bulldogs are known for their lovable, jowly faces and unique personalities. They are friendly and approachable with humans but can be territorial, making them excellent guard dogs. Today, Bulldogs have evolved significantly from their aggressive ancestors.


2. Labrador Retriever
The Labrador Retriever, often affectionately called 'Lab', is a widely known hunting dog breed in the US. They belong to the gundog group and are typically used to retrieve game for hunters. The name 'Labrador' originates from the Portuguese word 'labrador', meaning 'worker'. Historically, the breed was favored by sailors and fishermen in Newfoundland and Portugal. Labradors are known for being gentle, friendly, and human-oriented, making them one of the most popular breeds in the US for many years. These dogs are energetic, reliable, lovable, and easy to train, and many Americans consider them part of the family. In Russia, they are also called 'Labriki', 'Laby', or 'Labukh'. The breed's ancestors were the Newfoundland dogs of Canada, originally helping fishermen by pulling nets in icy waters. Labradors were brought to England in the 1800s, where their retrieving instincts were further refined. They are now commonly kept as family pets due to their affectionate nature, intelligence, and ease of training.
Labradors have proven themselves in a variety of roles, such as detecting explosives, guiding the visually impaired, and assisting people with disabilities. Honest, calm, and smart, they are great with children, offering a sense of security and satisfaction. Their exceptional sense of smell made them valuable in both World Wars for locating landmines and explosives, and today they are used to detect illegal drugs. Labradors are generally kept indoors and require ample space due to their rapid growth. Nearly 80% of guide dogs worldwide are Labradors. As hunting companions, Labradors are invaluable: they work tirelessly, track game with precision, and respond quickly to commands, excelling in their role. They can accurately locate fallen game, both on land and in water, and possess an excellent sense of smell, even tracking blood trails days after the hunt.


3. Rottweiler
The Rottweiler, also known as Rotti or Rott, is a breed originating from Germany, originally used as a herding dog but later trained for specialized work. These dogs are also formidable fighters and have a high tolerance for pain. Rottweilers are strong, intelligent, and while their large, imposing appearance may seem intimidating, they are well-behaved and serve as excellent guard dogs. They tend to be aloof with strangers but are affectionate with those they know. Typically calm in demeanor, Rottweilers are known for their pack mentality and protective instincts. Dangerous behavior in Rottweilers often stems from neglect, abuse, or lack of training. Despite their intimidating reputation, they are among the most reliable guard dogs, with a bite force that can exceed 136 kg. The Rottweiler is a well-known breed, with individual dogs often costing up to $3,000. The breed is named after the town of Rottweil in southern Germany, where it was first discovered. Rottweilers are descendants of the Italian mastiff, and the breed was developed in the town of Rottweil in Württemberg, Germany, appearing first in the 1800s. The breed gained popularity in the mid-20th century, thanks to breeders in Stuttgart.
Historically, Rottweilers were used for herding livestock, with their ancestors dating back to Roman times. These early dogs were utilized in war, hunting during the medieval era, and for pulling carts in place of horses. From 1910 onward, the Rottweiler was officially recognized as a police dog. While initially a herding dog, the Rottweiler was later trained for search-and-rescue, guiding the visually impaired, and as a police and guard dog. Today, Rottweilers are still valued for their tracking, herding, guarding, search-and-rescue, and police work. They are known for their strong and versatile nature. While Rottweilers can be protective and territorial, they are generally calm and reliable, making them excellent companions for families and workers in law enforcement.


4. Boxer
The Boxer is a breed of fighting dog that originated in Europe through the crossing of the Bulldog and the German Mastiff. Their name comes from their tendency to use their front paws like boxers in a fight, a behavior that gives them their distinctive look, including the white markings on their paws that resemble boxing gloves. Boxers are highly energetic and agile, making them ideal competitors in dog sports. However, training them requires early intervention, as they can be quite stubborn and independent. They are affectionate with people, especially children, and are loyal protectors. Since the 19th century, Boxers were bred for combat due to their ability to stand on their hind legs and fight their opponents. While not overly aggressive, there have been 48 reported accidents involving Boxers between 1982 and 2012. Known for their playful, high-energy demeanor, they can also be a bit headstrong at times.
The ancestors of the Boxer breed include two German mastiffs, the Bullenbeiszer and Barenbeiszer, which were later crossed with the Bulldog. Historically, Boxers were used in bull hunting and as draft dogs. Over time, the breed moved away from its origins and became popular in military forts, where they were used for herding cattle. They also gained fame in circuses and traveling shows due to their quick learning ability. Boxer breeding was somewhat chaotic until 1904 when breed standards were formalized. Although originating in Germany, their name is derived from their boxing-like stance. Today, Boxers are considered one of the best family dogs and excel in roles such as guarding, police work, and search-and-rescue operations.


5. Rabbit Hunting Dog (Beagle)
The Beagle is a small breed of hunting dog, primarily used for rabbit hunting. They are easily recognizable by their smooth, tri-colored coat and their friendly, affectionate nature. Beagles are great companions, known for their sociable demeanor, and they make wonderful family pets, especially around children. These dogs love to explore and, when allowed to roam freely, they will happily embark on adventures thanks to their keen sense of smell. The name 'Beagle' comes from the word 'be'geule,' referring to their distinctive howling after a hunting session. Beagles are also friendly towards other dogs and people, making them one of the most sociable breeds. Although they share similarities in appearance and temperament with the Basset Hound, Beagles are often seen as a more active and energetic breed. Their exact origins are unclear, but it is believed that they have been bred in England for over 500 years, possibly from crosses between the Harrier and other English hunting dogs. Beagles are often used for pack hunting but can also work individually to hunt rabbits, pheasants, and quail. They have also been trained for more specialized roles such as detecting drugs and serving as loyal family pets. Beagles are known for their ability to work in small packs and their intelligence makes them excellent in roles requiring sharp noses. With their manageable size, they are also commonly used in scientific research. The Beagle is classified as a small hound and is recognized for its high adaptability, whether hunting in the UK or working as detection dogs in Sri Lanka.
The Beagle is a small, square-built, robust dog with a healthy physique. However, their popularity has led to overbreeding in some lines, which has unfortunately resulted in health issues. These can include heart problems, epilepsy, vision issues, back problems, and joint problems. Beagles can live 12 to 15 years, with litters ranging from 2 to 14 puppies, with an average of seven. Their coat is short and glossy, requiring minimal maintenance. They come in a variety of color combinations, including tri-color, black and tan, red and white, lemon, and blue-tick. Beagles have round, sturdy feet, a broad, slightly round skull, and a straight, square muzzle. Their wide, drooping ears and large brown or reddish-brown eyes give them a pleading expression. Their tails are always wagging, though they are never curled over their back. Beagles are known for their distinctive baying and barking sounds, which can be music to the hunter’s ears but might disturb the neighbors. These dogs have an innate tendency to follow their noses, which can lead them into mischief.


6. German Shepherd (Alsace)
The German Shepherd, also known as the Alsace dog, is a large breed native to Germany. In Vietnam, this breed is often referred to as the Berger, a term derived from the French word 'berger' meaning 'shepherd dog'. The German Shepherd is a relatively modern breed, first recognized in 1899. Originally bred to herd sheep, these dogs are known for their strength, intelligence, and obedience, making them popular choices for police and military work. Due to their loyalty and protective instincts, they are also among the most registered dog breeds in the world. Typically, German Shepherds stand between 55 to 65 cm tall and weigh between 22 to 40 kg, with an ideal height of 63 cm according to the Kennel Club standards. They have a rounded head, a long, square-shaped muzzle, and a black nose. Their strong jaws are equipped with scissors-like teeth. The eyes are medium-sized, brown, alert, intelligent, and confident, while their large, erect ears are typically positioned forward and parallel, but often fold back when they are in motion. The breed’s long neck is typically raised when excited and lowered when running quickly. Their bushy tail extends to the hock.
The German Shepherd comes in a variety of colors, with the most common being dark/black and red/black, with several variations. These colors include solid black, sable, black and tan, and liver, while rarer colors like blue and liver are sometimes considered faults in the breed standard. White is often deemed an immediate disqualification as it makes the dog too conspicuous, failing to blend in for tasks like guarding or herding in snowy conditions. The coat of the German Shepherd consists of two layers: a dense undercoat and a coarser outer layer. The outer coat comes in two types: long-haired and medium-haired, with long-haired being a recessive trait. Known for their exceptional intelligence, German Shepherds are considered the third smartest dog breed, behind the Border Collie and Poodle. According to Stanley Coren’s 'The Intelligence of Dogs,' this breed can learn simple tasks in just five repetitions and follows commands with a 95% success rate. Their intelligence, combined with strength, makes them ideal for roles such as police dogs, guard dogs, and search-and-rescue dogs, as they excel in learning tasks and understanding instructions faster than most other breeds.


7. Siberian Husky
The Siberian Husky is a medium-sized dog from the sled dog breed, originally hailing from the cold northeast region of Siberia, Russia. Huskies belong to the Spitz family and are known for their thick double coats, triangular ears, and distinct markings. These dogs have a love for physical activity, which traces back to their ancestors who were bred by the Chukchi people of Northeast Asia to pull sleds across long distances in extreme cold. Huskies were brought to Alaska during the gold rush in Nome and quickly became popular in the U.S. and Canada. Initially bred as working sled dogs, Huskies eventually transitioned to household pets. The Siberian Husky, along with the Samoyed and Alaskan Malamute, shares a common ancestry, as DNA testing in 2004 confirmed. Introduced to Alaska in 1908, they were used for sledding and racing, where they quickly became the preferred choice for pulling sleds.
The Husky's coat is denser than most other dog breeds, with two layers: a soft, short undercoat for insulation and a longer, coarser outer coat to shield against the extreme cold, allowing them to withstand temperatures as low as −50 to −60°C. Huskies shed their undercoat frequently and need regular grooming, especially if living with humans. They come in a variety of coat colors, with the most common being black-and-white, brown-and-white, grey-and-white, and the rarer agouti. Huskies' almond-shaped eyes are typically set apart and slightly slanted, with colors ranging from sky blue, sea blue, amber, green, and brown. Some Huskies have eyes of different colors, or even a mix of blue and brown (parti-colored). These eye colors are all considered acceptable for purebred Huskies. Their tails are long and thick, often curled over their backs during activity to retain body heat. When resting, Huskies curl their tails over their faces to keep warm. Their tails droop when relaxed and curl up when excited or curious.


8. Jack Russell Terrier
The Jack Russell Terrier, also known as Russell Terrier or Parson Jack Russell, is a small breed of terrier originating from the fox hunting dogs of 19th century England. This breed is highly skilled at digging and hunting small rodents. The name ‘Jack Russell’ was derived from Reverend John Russell, a passionate hunter who first bred the fox-hunting dog. For many years, the term 'Jack Russell' described a wide range of small, white terriers, but after a legal dispute, the Jack Russell Terrier Club of America (JRTCA) and its branches secured exclusive use of the name to refer to their specific breed, a unique branch of terriers known for their agility, cleverness, and survival instincts developed over the past 200 years, starting in the 19th century.
This is a small breed, predominantly white in color, with either smooth or rough coat textures. They typically weigh between 5 to 7 kg and stand about 30 to 35 cm tall, making them compact and agile. Their small heads and often bushy muzzles, with a sleek coat, are distinctive characteristics. Their noses are black, and their bright eyes are usually brown or black with a ring around them. The body’s height and length are well-proportioned, giving them an athletic, balanced appearance. Due to their hunting and burrowing nature, their chest is small, minimizing wind resistance when chasing prey or digging holes. They come in two coat types—rough and smooth—both with durable, dense fur. Their coat is predominantly white, but they may also have brown, lemon, or black markings, often found around the head or tail. Some Jack Russells have a pure white coat with black or brown eye patches. The average lifespan is 14 to 15 years.


9. Pug or the Wrinkled-Face Dog
The Pug, often referred to as the 'wrinkled-face dog', is a small companion breed originally from China. They are known for their wrinkled face, short muzzle, and curled tail. Pugs have a smooth, glossy coat, which comes in various colors, with black and fawn being the most common. Their compact, square-shaped bodies are well-muscled and robust. Pugs were brought from China to Europe in the 16th century and gained popularity in Western Europe, especially in the Netherlands' Orange-Nassau family and the Stuart dynasty. In the 19th century, Queen Victoria developed a great fondness for Pugs, and her passion spread to the royal family. Pugs have remained popular up to the 21st century, with many celebrities owning this breed. A Pug even won the World Dog Show in 2004. The breed's origins date back to around 400 BC in Asia, though their exact origins remain debated. Some experts believe Pugs originated in the Far East, brought by Dutch traders, while others suggest they may be a branch of the short-haired Pekingese or the result of Bulldog breeding.
The Pug is well-balanced and compact, with a body that is nearly square in shape, as the height at the shoulder is close to the length from the shoulder to the rear. The standard Pug's body resembles a pear shape, with broader shoulders than hips. Their short, soft coat is easy to groom and comes in a variety of colors, including fawn, black, and brindle, often mixed. Their skin is soft and pleasant to the touch. Pugs have large, round, dark eyes, and their underbite gives them a charming expression. Their tails are either straight or curled. Proper care of their wrinkles is crucial, as Pugs have a short nose and lack bone structure above their eyes, making them prone to eye injuries like prolapsed eyes, scratched corneas, and entropion. Their airways are narrow, making it difficult for them to breathe and regulate body temperature through panting. A Pug’s normal body temperature ranges from 38°C to 39°C. If their temperature rises above 41°C, they require immediate cooling, as temperatures above 42°C can cause organ damage. Breathing difficulties in Pugs can worsen if they experience stress, especially during air travel, where they are often confined to small spaces with high temperatures. Because of this risk, many airlines have restricted the transport of short-nosed dogs, especially in warmer months.


10. Dalmatian Dog
The Dalmatian, also known as the 'spotted dog', is a domestic breed originating from the Dalmatia region (part of Croatia), where the breed was first found. This breed is easily recognizable by its white coat with distinctive black spots, and is sometimes affectionately called the 'raisin pudding dog' because of its unique pattern. Originally bred as a carriage dog and scent hound, the Dalmatian is highly energetic and loves to run. They became widely known through the animated movie '101 Dalmatians'. The Dalmatian is renowned for its sleek, muscular build and striking appearance, making it one of the most beautiful dog breeds in the world. Their unique coat pattern of black spots on white fur adds to their charm and makes them stand out in the dog world.
The Dalmatian has a well-balanced, athletic body with remarkable endurance. Its short, thick, and stiff coat is primarily white with randomly distributed black or brown spots. These spots can vary in color, including black, brown, lemon, dark blue, or even pure white. Dalmatians with hearing impairments can be more challenging to train and may develop aggressive tendencies as they mature. Additionally, kidney stones and allergies are common health issues for this breed. Dalmatians are the only dog breed known to suffer from gout because they are one of the few mammals, besides humans, that produce uric acid. Their uric acid levels are higher than in other breeds, so they require a low-protein diet to maintain their health. Adult Dalmatians typically weigh between 16 and 32 kg, with a height ranging from 48 to 61 cm, with males usually being slightly larger than females. Their paws are round, with arched toes, and their nails are often white or match the color of their spots. Their ears are thin and taper towards the head, set high and close to the skull. Eye colors can vary from brown, amber, or blue, with some Dalmatians even having one blue eye and one brown eye, or other unique combinations.
