The saluki I would bet is a show animal and is shallow in the chest without good rear angulation. The greyhound and wolfhound both have the chest depth to their elbows and good rear angulation. After 40 plus years being involved with performance APBT'S those are factors which enhance a dogs endurance. It isn't something I just "like."
Sir, i did not get the picture of the Saluki off a Google search. I got the picture from a guy that makes a living hunting them. However the 2 dogs you are crediting are show dogs lol. Sir, i know you try hard but i really don't think you understand performance beyond that of a show ring or computer screen
