Spaniels and Aulstralian Shepards have both been bred as working dogs... so they should have drive to them....
If you look back, almost every (distinct) breed had a purpose with some sort of necessary prey drive, whether it was herding or hunting of any given type of game. Some have just about had it bred out of them for pet and show animals because it isnt needed....but if given the opportunity you can almost always tap that natural instinct, some will excel and others will fail miserably just as not every coyote pup wouldnt make it.
