They appear in Greyhounds which are in your dogs, but what you are saying is you have no experience of really flat feet because they dont occur in the dogs you keep (not breed) So everything you have said so far means nothing as usual because you have no experience as usual. You really are a bit thick mate. As far as bad mouths are concerned in saluki types, its simple they are lacking drive. If my dogs turn out with flat feet, lack of drive, gameness or wind then I take them out of the breeding program. Thats something else I believe you only have negative experience of.
