Seizure alert dog offers hope of independence:
When Gracie picks up on the smell, largely imperceptible to humans, that Lindsay gives off before she seizes, the dog is to pull the cord on a small alarm that Lindsay wears on a belt. That's the signal for Lindsay to sit or lie down so that she won't hurt herself during a fall, and for adults nearby who hear the alarm to come to her aid. When Lindsay comes to, she snaps a metal clicker and gives Gracie doggie treats from the pink fanny pack she wears all the time - the signal, in dog language, that Gracie did a good job that she should repeat next time.
