spot on , yeh you right just go for a pup from proven workers , and regards coat it works both ways as in the winter a dog with good coat like my 2 dogs can take what ever the weather throws at them , but there fooked in the summer . i had a bitch lurcher x lurcher who was near enough 90% running dog just drop of collie her coat was just like greyhound but just bit thicker , she was ok in the winter , and when lamping no prob , a x i've always liked is pit x grey x whippet x saluki x grey you get good dog there not to big and run all day/night and bit of grit .
