hi there , welcome to the forum
you can only work your dogs on rabbits and rats as everything else is banned now mate , but if your mate goes ferreting maybe you would be better with a beddy x whippet or a colliex whippet , no need for a big dog 23 24 tts is plenty big enough for bunnys , have a good read round the lurcher section , dont be afraid to ask and dont take things to heart as some members on here are only here to cause trouble and row .
hope this helps , atb Fezz
