My first rescue Ibizan Hound Minny did the same or better.
My woodstove backed up and I was unconscious from the smoke that had filled the whole house.
I came to with her jumping up and down on my chest, barking in my face.
It was dog CPR.
If not for her, she, I and my other dogs would have simply died that night.
WOW! Dog is God spelled backwards. :-)
Far as I’m concerned most of them are like angels...who watch over us and help when needed. I had a standard poodle who I think saved my life one night. She was part of me - oh how I miss her.
Rescue dogs are often very grateful and show it in many ways.
A floor plug had shorted out and had caught the sofa on fire. Bobo kept our house from burning down. Good dog!
