a 3/4 greyx lab, would make great lurcher. Some working labs are racey, good nose,stamina,strong, coat, brain. Ive always thought would make better x than a collie, but i think you need as said a 2nd x. A dog with natural retrieve, with 3/4 grey plenty of [speed+guts] to tackle any quarry. plus alot of labs make good guard dogs.and lot calm'er temp than a collie x I really [dont] know why the aint [popular]
