Those ears more that quadruple the amount of sample for the dog to scent. Most Cur dogs don't have longer ears and Brits aren't too awful long either. Curs aren't the greatest scenters as they have a tendency to pick up a very hot trail then catch sight of the hog. Brits are pretty much the same, they pick up hot bird sign then they use their spectacular vision to lay eyes on the bird then go to point. Neither dog has spectacular noses in the first place.
