1. Siberian Husky
The Siberian Husky is a medium-sized sled dog breed originating from the Northeast of Siberia, Russia. Genetically, Huskies are classified as Spitz-type dogs. They have a double coat of thick fur, erect triangle-shaped ears, and often have various markings on their coat. Huskies are highly active dogs as their ancestors lived in one of the coldest places like Siberia, where primitive Huskies were bred by the Chukchi people in Northeast Asia for the purpose of pulling sleds over long distances in harsh cold conditions. This breed was brought to Alaska during the gold rush in Nome and later became popular in the United States and Canada. Initially bred for sled-pulling, Huskies eventually transitioned to become family pets.
Huskies are highly active dogs as their ancestors lived in one of the coldest places, Siberia. However, nowadays, Huskies are raised in many places around the world and mainly kept as companions in families. Their fur is quite thick, with the distinctive feature being their eye color. Huskies have almond-shaped eyes, slightly slanted, with various colors like blue, aqua, amber, green... Some dogs even have two different-colored eyes. Huskies have a resemblance in appearance and behavior to their ancestors, the wolves. They tend to roam and seek escape from confinement. However, they are very suitable for protecting children and infants. Owners should pay attention to training these playful dogs strictly. The Husky breed, known for its beauty, is favored by many people, so their price is quite high, especially purebred Huskies.

The Pitbull is a breed of domestic dog originating from America, bred in England for home protection and also used in dog fighting. They are a selected breed from the Bull and Terrier breeds. They are known for their ferocity, tenacity, courage, and are dubbed as cold-blooded killers or warrior dogs. The first Pitbulls were bred in England in the 18th century for fighting other dogs in the pit or in a large hole for gruesome battles. They were also trained for hunting. As a foreign breed originating from America, they are highly aggressive and combative. This breed has its roots in America and is gradually becoming popular in Vietnam. Considered the demon of dog fighting breeds, with their powerful bodies and sharp teeth, Pitbulls are like warriors, capable of fighting until their last breath. Pitbulls are used more in dog fights among some fighting breeds and excel in protecting territory and their owners. They have an average weight ranging from 30 to 40 kg, appearing very strong and ready for mortal combat when commanded by their owner. This breed is medium to small-sized, standing from 45 to 55 cm tall, weighing from 18 to 22 kg, with more muscle strength than any other breed. Generally, Pit Bulls have a tough appearance, with sturdy bone structure, solid muscles, and particularly intimidating red eyes under a large forehead. Known for their muscular physique and especially their fierce, rugged appearance, they are often perceived negatively due to their intimidating appearance.


4. English Bulldog
The English Bulldog, also known as Bulldog or Bully, is a large-headed, robust, and courageous breed from the United Kingdom. Bulldogs have their origins from ancient Asian mastiffs but truly flourished in England. Initially bred for bull-baiting, they were later used as watchdogs. Highly revered by many universities and institutions in the UK and the US, Bulldogs are increasingly chosen as pets due to their temperament and appearance. They are also known for being lazy and prone to obesity due to their fondness for eating and reluctance to exercise. This breed has a long history of development. The name Bulldog originates from their strong, bull-like appearance and their strength, derived from their sturdy, muscular physique, reminiscent of muscle-bound bulls. Bulldogs are known for their enduring vitality and readiness for combat, especially during the bloody battles against bulls. These bloody fights were banned in the 19th century and remain prohibited to this day. Bulldogs have undergone significant changes, especially in the 19th century, when standard dog fights became popular. Initially, Bulldogs were used as bait dogs in bull-baiting. At that time, they had higher hindquarters than their descendants. In 1835, bull-baiting was banned in England, and Bulldogs were transferred to dog fighting, but in this field, Bulldogs were less favored than Bull Terriers because the latter were smaller and easier to conceal during illegal dog fights. Consequently, the Bulldog breed became less popular. However, their image has since been revived to become a popular companion dog. This breed can be considered as one of the important factors contributing to the creation of some new dog breeds through genetic engineering. Typically, people choose the favorable traits of Bulldogs for breeding new dog breeds such as Bully Dogs or Bully Terriers. It is because of these good qualities that breeders have selected them. Bulldogs have short legs, unattractive faces, and often pant heavily, but they are very gentle, courageous, and easy to groom.

9. Saint Bernard Dog
The Saint Bernard is a very large breed of dog from Italy and the Swiss Alps, originally bred for rescue purposes. This breed became famous through stories of alpine rescues, as well as its massive size. It is the result of crossing the native Swiss dog with the Mastiff from Asia, when they accompanied Roman legions on their invasion of the Alps. Over the first two centuries AD, they flourished and became widespread. Centuries later, Saint Bernards were used in special missions, gradually also being bred on farms to herd sheep and livestock. In monasteries and hospices, they followed monks on rescue missions after avalanches. This large breed of dog has been used for hauling, guarding treasure, and herding sheep on farms.
Today, the Saint Bernard is still bred as a rescue dog in high snowy mountain regions, often depicted as a giant dog, wearing a keg of strong liquor around its neck (used for reviving and warming up victims buried in snow). The Saint Bernard is a giant breed. The average weight of this breed is between 140 and 264 lb (64 - 120 kg) or more, and the approximate height at the shoulders is from 27 ½ inches to 35 ½ inches (70 to 90 cm). The coat can be smooth or rough, with the smooth coat being thin and flat. The rough coat is thick but flat, more so around the neck and legs. The coat usually has red and white colors, or sometimes a mahogany with white. Shiny black is often found on the face and ears. The tail is long and heavy. The eyes are usually brown, but sometimes can be icy blue.
