hi all. as some of you might know iv been looking for a collie grey for my first lurcher in about ten years but as most of them was to far away to pick up i just bought my self a ten month old whippet x greyhound, sir whippet, dam greyhound.. but im just woundring coz it only stands about 21 tts have i just been told a pack of lies. or is that the size of some of them. i own 3 greys my self and just thought any pup out of one would have been bigger
