My old bitch was very like him,very salukified,and had the same long flat feet all of her life,used to glide effortlessly with a very light footed floating running style,used to make her look like she was'nt trying,but when you looked at what she was running,you could tell she was motoring,roadwork did'nt alter her feet,but she was very durable,only remember her having one toe injury after running flat out down a bank and across a road on the back of a hare
