I’ve read numerous on these pages anecdotes about people who have dogs that detect and assist with low BG episodes. There is also a great resource here plus numerous articles, including the AKC magazine Family Dog at www.akc.org.
One of mine (a Siberian Husky) gives subtle hints, (including lots of licks when I start crashing, yet I’d love to improve his skill without having to go through lows to train him. Does anybody have any thoughts or recommendations for doing this?
