As a purebred race horse, the Greyhound has no rival as a hound and runner. Its morphology eases its task perfectly: running. 
The Greyhound has a symmetrical structure, with magnificent proportions, a long head and neck, a great capacity body, powerful hindquarters, arched kidneys and shoulders well sloped backwards. The head is long and narrow, very wide between the ears: a barely visible stop. The ears are small, with a fine texture, with a rise shape. The jaws are potent and well chiseled. The eyes are bright and intelligent, oval shaped and set obliquely; preferably dark colored. The shoulders muscled with the appearance of being loaded. The forelegs perfectly straight, the chest deep and wide thorax. The lumbar area is powerful, the lower outline retracted at the sides. The hindquarters very muscled, well angled; the hocks low. The feet are hard and tight, described more as hare than catlike. The tail, low inserted, is long and fine, narrowing at the end, slightly curved. The coat is short, with a firm texture. The color includes black, white, red, blue, fawn, wheat, brindle or any of these combined with white. The male weighs between 32 and 35 kg; the female, 2.5 kg less. Ideal size for the FCI is 71 to 76 cm in the males and 68 to 71 in females.
WHO IS IT RIGHT FOR             
The Greyhound is the race horse in the canine world, incredibly fast and with an aristocratic stance. In addition it is a charming dog, which can be an excellent companion for families or people willing to accept the responsibility that this breed implies. It is a gentle dog, not nervous as said; it is a child of the wing, which mean that when it goes for a run it can to so at 70 km/h (and that it why it needs a fenced space and supervision). Greyhounds retired from tracks are excellent company animals for the right person.
A gentle animal, the Greyhound is as affectionate and calm as a domestic dog and a resistant athlete with incredible speed. 
Since many people acquire an adult Greyhound, retired from race tracks, few owners have the pleasure of raising and watching Greyhound puppies grow. In fact, only a handful of non race intended litters are born each year, compared to the hundreds race specimen litters.
Size at birth varies considerably but is 500 g or more in general; females are smaller than males. The puppy is born with a very long tail in proportion, and it grows into it. Special attention should be provided during the puppy stage to avoid tail injuries. Color is not limited by the standard, and in the Greyhound every color is admitted. Some colors may change with age. The Greyhound grows at a good pace and reaches its maximum height at around nine months. The adult Greyhound is a high energy dog that requires abundant physical activity and the possibility of venting by running. The Greyhound must keep its shape and should be provided an appropriate diet.
If bred around people and other dogs, the Greyhound puppy turns into an obedient, fun loving companion. It is easy to socialize and very adaptable to the family life. 
The Greyhound is proud of being a large size breed free of hip dysplasia! The owner should be warned that the breed is sensitive to medication, including some filariasis preventives and sedatives. 
Perhaps the most athletic of domestic dogs, the Greyhound demands abundant exercise. It is essential to have a space with a high fence (they are great jumpers as well!) where it can play and run freely. The breed has proven to be very healthy and exempt of common problems as hip dysplasia. It is known that the Greyhound is sensitive to pharmaceuticals, especially sedatives, in part due to its low body fat. Hemophilia A is also reported, which manifests by hemorrhages. Longevity is over ten years; however, some ex runner only live seven years, due to the race rigors and possible steroid use. Some Greyhounds proceeding from a dog track and adopted by a family will need extensive dental care and Nylabone®, since its teeth is very abandoned from professional cleaning can help reduce bad breath. Superfluous teeth are frequent.
