i grew up with a half x,good dog on all quarry,if it is your first lurcher i would get a collie x,in my opinion i find them easier to train,but as others has said they can allso be hard work,i know a boy who had a brilliant 3/4 greyhound 1/4 collie,he would catch hares for fun on the lamp,pick up rabbit after rabbit,take fox and deer,then all of a sudden at 3 years of age he turned crazy,attacking sheep,dogs,and he tried to attack its owner who is a big lump of a boy,he wouldnt let him in the run or anything,the dog was put down because the lad had young kids,and the dog couldnt be trusted,but
