Used to have a mick brown bred dog out with us on a Sunday with the terriers, stood 22.5 fairly strong built for a whippet , would stick his head in at the end of a dig and even travel underground, used to walk to where the hares were and catch one if you got close enough before they got to fidgety, because he was brought up with lurchers from a young age he acted and worked like a lurcher , muntjac were taken single handed by him although I didn't see this ,this was in the nineties before the laws changed for the worse
