Merlin has never saved my life but he may some day. He knows when I am haveing a too high or too low of blood sugars. I'm diabetic
he has a way of making me get to tht bathroom to test so I know . He NEVER goes there alone that hated bathtub is there. So I know he's picking up on me so I test myself(sometimes it's like I have two husbands). I never trained him for this it just started happening and we found a pattern so now I have a second back up if I miss the clues.
