Thats right, my mom just told me how Tucker saved her life today! She was laying down taking a nap and heard Tucker barking like a mad dog. She told him to be quiet but he just kept right on going. She said he was going crazy jumping and running around. After a few more minutes she got up and it turns out her blood sugar had gone down very very low. Its back up to normal and she's fine now.
I really think Tucker could tell something wasn't right and probably saved her life! This does happen with her every once in a while,(but not since we've had him) so I guess we found out what Tucker's service can actually be.
