My Shih Tzu, ChiChi, saved my life and has gotten me help twice when I didn't realize my sugar dropped drastically.
Just after midnight once, she jumped on my stomach making me roll out of bed. And another time, she ran to the other bedroom and awakened my friend who came to see what was wrong and I wasn't responding. SO, they called for help. Love is so great that if I don't pay her attention while she is eating she just won't eat. She even more valuable that you can imagine. But, I'd love her to pieces.
