Hi. This is my first post but have been diabetic for 41 years. I've always been able to tell when I'm going hypo but recently I have had no warning signs. Does anyone else ever have this? I've got a clever girl dog who is not trained with any illness but she makes me aware and also alerts my husband. She is the 2nd Labrador that we have had that has done this. The first one sat on my chest to wake me up. Such clever things.
