So in that case it is purely his build and shape which don't lend themselves to sustained running on the back of a hare. I used to see it a lot when I ran hares with 'hairy' dogs, heavier built and more muscley than Saluki types. Even at their fittest, they couldn't last behind a good hare, and they paid for it afterwards. It's a bit like asking Linford Christie to run a marathon.
See i use toby as an out and about dog if he puts it up and in the bag im happy ,but i am just happy to be out with the dogs they dont have to catch thats just the bonus part ,but i do put all i can in time and
