My sister found my family's German Shepherd (Q) 8 years ago at a shelter. Needless to say, we love him incredibly. We were very sad when he went missing for a few days some years ago, and thrilled when we recovered him safely from a shelter, the following day.
While not based on literal events, I just made a short film starring my dog which I thought you might like. If you feel like sharing with others, please do!
Enjoy!
