One of my adult students (and friend) is learning how to sew and make service vests for her service dog Hero.  She completed the first one, Harry Potter themed and is working on the second one, Super Hero themed.  Her service dog is named Hero.  Hero is a very special service dog with a very special ability that very few dogs have.  He can sense when she is about to have a seizure and can alert her so that she can immediately take the necessary steps to allow Hero to lay on her to keep her still until the seizure is over.
