Sighthounds are a special type of hound dog. 

These dogs have unique bodies for running. They have long legs for big strides. Their backs are very flexible. They also have deep chests. This helps hold a very large heart. Their lungs are also very efficient for sprinting. 
Sighthounds have been around for a very long time. Some types may have existed for 5,000 years. Today, many people keep them as pets. They still love to run and play. Some dogs even join sports like racing or lure coursing.
Sighthounds are a special type of hound dog. 

To catch fast prey, sighthounds have unique bodies. They have very long legs to make a long stride. Their backs are also very flexible. A deep chest helps them hold an unusually large heart. They have efficient lungs to help them during fast sprints. Most sighthounds have a long, lean head. This shape is called dolichocephalic. This head shape may help them see more of the world around them. 
Sighthounds have been part of history for a very long time. Some types may have existed for at least 5,000 years. For example, remains of a male sighthound were found in Tell Brak. This discovery was dated to about 4,000 years before the present. In the 2nd century C.E., a writer named Arrian described a sighthound in Roman Spain. A skeleton called the Warmington Roman dog was also found in England.
Scientists have studied these dogs to learn more about them. In the 8th or 9th century, bones of a 70 cm high dog were found. These bones were called "gracile" bones. DNA tests showed they were almost identical to modern Greyhounds. Most sighthounds today are kept as pets. However, they still have a strong instinct to chase running animals. Many sighthounds enjoy sports like racing or lure coursing. 
There are many different breeds of sighthounds around the world. The Afghan Hound comes from Afghanistan. The Borzoi is a Russian hunting sighthound. You can also find the Saluki from the Middle East. The Whippet is a breed from England. Some dogs are even mixed, like the Lurcher. A Lurcher is a mix between a sighthound and a herding dog or terrier.
Sighthounds, often called gazehounds, are a specialized group of hunting dogs. Unlike scent hounds, which rely on their sense of smell and long-distance endurance, sighthounds hunt primarily through vision and extreme speed. 

The anatomy of a sighthound is a complex system of specialized parts. To catch fast, agile prey like hares or deer, they require a very flexible back and long legs. These long legs allow for a massive stride during a chase. Their bodies are lean and wiry to keep their weight at a minimum. A deep chest is a vital feature because it supports an unusually large heart. 
Vision is perhaps the most critical sense for these dogs. Most sighthounds possess a dolichocephalic head, which means they have a long, narrow skull. This specific head proportion creates a wider field of vision. While this shape might result in less overlap between the eyes and potentially lower depth perception, it offers other advantages. Evidence suggests that dolichocephalic dogs have a higher number of retinal ganglion cells in their "visual streak." This anatomical feature helps them maintain heightened sensitivity to objects and rapid movement within their horizontal field of vision. This allows them to spot movement across a wide landscape very effectively.
The history of sighthounds stretches back thousands of years. Excavations at Tell Brak have revealed the remains of a male sighthound, likely a Saluki type, dating to approximately 4,000 years before the present. 
Genetic research has helped connect ancient dogs to modern breeds. In the 8th or 9th century CE, researchers identified "gracile" bones from a dog standing 70 cm high. Genetic analysis of these remains showed they were almost identical to the modern Greyhound. The DNA sequences showed only four deletions and one substitution compared to modern dogs. This suggests that the modern Greyhound breed has changed very little through only 11 centuries of breeding. Recent genomic studies also propose a "multiple origins hypothesis," suggesting true sighthounds originated independently from native dogs and then mixed among various breeds.
There is a massive variety of sighthound breeds across the globe. For example, the Afghan Hound originates from Afghanistan, while the Borzoi is a Russian hunting sighthound. 

Sighthounds are categorized differently depending on the organization. In many English-speaking kennel clubs, like the American Kennel Club, they are placed in the Hound Group alongside scent hounds. However, the Fédération Cynologique Internationale gives them their own dedicated Sighthound Group.
