Unfortunately, I do not have any suggestions for the OP, but once a man on the same plane as me was traveling with a dog. After a little conversation, he told me he had epilepsy and that the dog could sense a minute or two before the man was going to have a seizure and alerted him. This allowed the man to prepare for a seizure and if he was driving he could pull over to safety before the onset. I hadn't heard of this previously and found it interesting.
