As I understand it, there are several steps to canine hunting behaviour, and instead of completing the whole sequence, the various breeds tend to prefer certain steps to others. So heelers like to chase/fix, and maybe nip, but don't bite and hold (which would be the next step in the wild type), and scent hounds like the tracking step while sight hounds like the flushing step. All dog's noses may be more or less equal, but the average scent hound is more interested in sniffing out (and less interested in running riot) than the average non-scent hound, making them more suitable for tracking jobs. https://en.wikipedia.org/wiki/Prey_drive#Aspects https://en.wikipedia.org/wiki/Prey_drive#Aspects Lagniappe: https://www.youtube.com/watch?v=WWVMXLSS1cA https://www.youtube.com/watch?v=WWVMXLSS1cA (speedruns are trivial when the screenplay is on your side; in real life unlocking the next step may involve a bit of a grind and/or learning new gameplay: compare Mick Jagger [on our right] https://cdn.shopify.com/s/files/1/2508/8586/t/6/assets/description_image_marianne-faithfull.jpg?14243084856038419497 https://cdn.shopify.com/s/files/1/2508/8586/t/6/assets/descr... )
