Dog left for dead is returned to adoption shelter.

It sounds like she just gave the dog away. She didn't even change his microchip registration. If she had dumped him he could have ended up at a shelter and found help sooner. Who knows what the poor dog suffered in the years he was not cared for.  Rehoming is not so easy. It takes a responsible person giving the pet to another responsible person. Anything less risks a mess like what happened to Trooper.
