I have recently rescued a dog of 2 years and I'm not sure if this is a grehyound Italian or a greyhound, but obviously one or the other. looks like a race. with a weight of 21 pounds, which is in the middle of the two standards. Does anyone know of any key characteristic that distinguishes between the Italian greyhound and a greyhound?
