Sight hounds, also known as sight hounds, are a group of dog breeds specifically bred for hunting by sight rather than scent. They possess keen eyesight and a strong prey drive, allowing them to spot and chase down fast-moving animals. Common breeds in this category include the Greyhound, Whippet, and Saluki. These dogs are characterized by their slender bodies, long legs, and deep chests, which enable them to run at high speeds. Sight hounds are often known for their gentle temperament and can make excellent companions, though they require regular exercise to maintain their physical health and mental well-being.
