I have heard of scams in this area so you might be right. I removed the link. I believe that such dogs do exist, but they are rare.

i believe dogs can sense a lot on their owners. that doesn't mean it's by smell though. people just pin it on smell often as dogs nose is very good. that doesn't mean it's the only sensor they have.

Exactly. For example, the person could be emitting an extremely high-pitched tone before the seizure that is inaudible to the Human ear yet can be heard by the dog. Sort of like a camera flashbulb.

Possibly, but I feel behavior is probably the biggest tell for dogs.

Their owner starts acting funny right before a seizure comes on.

I have a tendency to let frustration build up until I lose my temper. The issue is that I don't realize I'm doing it until I'm ready to explode. My last dog was so sensitive to that, that she could tell when I was starting to get angry before I would realize it. I would be sitting at my computer, struggling with something, and I'd feel her poke me in the leg with her nose, then I knew it was time to take a break. I think she could hear that i was typing 'harder' when I got angry, but it could have been any one of a lot of tiny signals. Point is, she was consistently aware of me getting angry before I was. I miss that dog...

it may as well be that every dog senses it, and it is our ability to communicate with and understand the dog rarely reaches the level necessary for the information to be actually communicated.
