Was walking my 4 lurchers with a mate & his pet Lab all mine were on leads as where we were walking has a very high population of Hares. My mates lab was chasing them all ovef the place, obviously no chance of catching but still running them. Along comes farmer in his 4x4 laughing at the lab then puts down his window & says to me make sure you keep them Fcukers on leads??!!! Then he drives off!! Wtf so as long as dog not capable of catching hares is it not coarsing???
