Let me see, who do I believe?

A dog who was trained for $8,000 to save his owner's life, or a poster called "Screamname" who posts that totally bizarre screed?

The dog makes more sense to me.

But, the dog bites exactly the right button on the cellphone? That sounds like a tall tale. I would expect some kind of lever or large button that the dog could hit with its paw.
