Watch as this pooch’s human mom takes us into various phases of her dog’s transformation, from the x-ray that displays her dog’s failing health to the final frames where we see the outcome of a lot of work and sacrifice! Trust us, it’s worth it!

Experts say dogs do not really show expression on their faces, that they do not know how to smile and what we, as doting humans, may perceive as an expression has always been there. However, emotions are often amplified and enhanced with a wag of the tail! And even though experts say otherwise about our dog's “smile,” it does our hearts good to see happiness displayed on the face of our dog.

However, I defy anyone to look in the face of that pug by the end of the video and not see a sincere demonstration of self-satisfaction and joy! We say it is there and we love it!
