Four regions were found that may regulate life span, a breed characteristic that usually decreases with increasing body size. Regions associated with some behavioural stereotypes like herding, pointing and boldness were also identified. What can they do with this information? The study could have far-reaching benefits for dogs and their owners. With further research, dog owners and vets could use this information to customize the care, diet and medicines to the particular needs of their breed, and to identify and perhaps prevent breed-specific diseases.
