The Greyhound is a sleek, athletic sighthound renowned for its incredible speed and graceful build. Originally bred for hunting and racing, this breed is surprisingly gentle and laid-back, earning it the nickname "the 45-mph couch potato." Greyhounds have a short, smooth coat that comes in various colors and require minimal grooming. They are affectionate, loyal, and well-suited for families, getting along well with children and other pets. Despite their high speed, Greyhounds are content with moderate exercise and love to relax indoors, making them an elegant and loving companion.
