Wow, that is an amazing story, Happycats! Three cheers for Coconut!
It's incredible how animals alert humans to danger, saving lives in the process. This "sixth-sense" instinct is certainly well documented with many cases of animal intervention. Fascinating how they "know".. and how they respond on behalf of their people.
So glad to hear that your friend is recovering now - how frightening, this close call. Their dog certainly is a hero!
