fit lyk , 21yrs old been going with lurcher dogs before i could even walk ( on my dads shoulders ) got 1 dog, deerhound X lurcher, and a couple of ferrets, and just to say you can't beat ferreting on a fine frosty morning!!!!!!
i think the typical lurcher would do perfect collie X greyhound, my uncle worked his one for about 10 years and it was one of the best ferreting dogs i've seen, and she was just above knee height
