Department of Ecology, University of Oulu, Oulu, Finland, 3 This study aimed to create a simple procedure that requires no pre-training and to use it to measure differences in olfactory capacity across four groups of canines: (1) dog breeds that have been selected for their scenting ability; (2) dog breeds that have been bred for other purposes; (3) dog breeds with exaggerated short-nosed features; and (4) hand-reared grey wolves. The dogs were recruited on a volunteer basis from the Family Dog Project database and the Top Mancs Dog School, Budapest.

Similar products could be used for dogs, however it is important that whatever bait is used, it can be standardized across trials to have the same amount of scent and that the scent can be reduced across the levels reliably while still being motivating. This suggests that the Natural Detection Task seems to be a relatively reliable measure of pet dog olfactory ability after even just one test, however, future studies should assess the existence of breed differences in greater detail and with larger retest sample sizes to validate this reliability. There were five levels of increasing difficulty determined by the number of holes on the containers lid. They can also use their nose to detect bombs and drugs, which bloodhounds can but wont often respond to because they prefer to track.
