If a dog cant do both you have a problem..lamping is often classed by some as easy, and if this is the case, what easier hunting could there be as bolting rabbits with ferrets to a dog..had an outstanding lamping bitch, call her a lamping bitch because thats all I did with her, got an invite to bolt rabbits with ferrets to the dogs, she got 30 in one day..
as its already been said, a good dog should be able to do both..slight alteration, any DECENT dog should be able to do both
