"[Jet] is both a seizure alert dog and a psychiatric service dog whose owner has epilepsy, severe anxiety, depression, various phobias and hypoglycemia. Jet has been trained to anticipate seizures, panic attacks and plunging blood sugar and will alert his owner to these things by staring intently at her until she does something about the problem. He will drop a toy in her lap to snap her out of a dissociative state. If she has a seizure, he will position himself so that his body is under her head to cushion a fall.  Jet seems like a genius, but is he really so smart? In fact, is any of it in his brain, or is it mostly in his sniff?"
