What's frustrating about seizures is that generally there are no warnings. It's fascinating that a dog can sense/smell something, a change in the body chemistry, and be so useful. The owner is so smart to be proactive!
Indeed. As a side note, though it's important to point out to those who don't know any better. If you see anyone having a seizure after you call 911... 1. DO NOT stick anything in their mouth(it's an old wive's tale that they swallow their tounges and you can make the situation worse by causing choking
2. CLEAR the area of objects that can hurt the person while he/she is having a seizure
3. CUSHION the head of the person so the do not get a concussion while the seizure is happening
4. DO NOT restrain the person from movements during the seizure...just let it run it's course and protect them from foreign objects in the area.
5. MAKE sure their mouth is not obstructed in anyway so they do not choke on flem or vomit.
