I have a real world practical application that might make SnifTag
useful. One of my beloved English Bulldogs has seizures. She only has
the a few times a year, so it's not as bad as it could be. However,
the more they have seizures and the longer they last, the more likely
they are to become more frequent. The longer the seizure, the more
dangerous it gets, as it could literally raise their body temperature
and cook their brain.
Thankfully, has only had three. However, several months ago, my wife
and I came home to find that she had seizured while we were out.
