It's difficult for us to determine how our pets would react if they ever happened to witness us during a moment of distress. We'd like to think they would be concerned, and in a perfect world, they would do whatever they could to help us, even if just by alerting to someone else that help is needed.
But ultimately, we'll never know for sure how they'll react until we're actually in that kind of situation. That's when you really find out if your pet has their paw on the pulse, so to speak, and are ready to leap into action need-be.
