Dogs detect diabetics’ trouble, writes Kinsey Sullivan. A non-profit called Eyes Ears Nose and Paws is training dogs to assist diabetics. Don’s comment: This group is training dogs to detect dangerously high blood sugar levels, to nudge people to respond, and to summon 911 if they are unable via a canine-rescue phone. The cost of a trained dog is around $20,000. It would be interesting to see a cost effectiveness evaluation of this approach; it is cool in any event.
