Whippets are a medium-size dog averaging in weight from 15 to 30 lb (6.8–14 kg), with height of 18.5 - 20 inches (47 - 51 cm) for males and 17.5–18.5 inches (44–47 cm) for females. Whippets tend to be somewhat larger in the United States and Canada with their population in show, coursing and some race whippets required to be within the AKC standard of 18.5 to 22.5 inches (47 to 57 cm) for males, and 17.5 to 21.5 inches (44 to 55 cm) for females. Because colour is considered immaterial in judging Whippets, they come in a wide variety of colours and marking patterns, everything from solid black to solid white, with red, fawn, brindle, blue, or cream. All manner of spots and blazes and patches are seen, sometimes all in the same litter.
Whippets regularly compete in dog shows, lure course racing and are among the fastest of dogs running a course at 36mph.
Whippets are generally quiet and gentle dogs, and may be content to spend much of the day resting. They are loyal and friendly. Because of this, whippets are known to have been used in aged care facilities.They may bark or jump at strangers and animals and may protect their owner if threatened.
Male whippets are as easy to housebreak as females and tend to be one to two inches taller and three to six pounds heavier than females.
