The Italian Greyhound is a small breed of dog of the sight hound type, sometimes called an "I.G.". The true breed origins are unknown. The Italian Greyhound is the smallest of the sighthounds, typically weighing about 8 to 18 lb (3.6 to 8.2 kg) and standing about 13 to 15 inches (33 to 38 cm) tall at the withers. Though they are in the "toy" group based on their weight, they are larger than other dogs in the category due to their slender bodies, so owners must be careful when sizing clothing or accommodations. The Italian Greyhound's chest is deep, with a tucked up abdomen, long slender legs and a long neck that tapers down to a small head. The face is long and pointed, like a full sized greyhound. Overall, they look like "miniature" Greyhounds.
