I've seen this several times; over-whelming desires to cry always hit me no matter how many times I've seen it before.I am glad this dog managed to pull through and got a good family.
That's a pretty heart-wrenching story and photo (maybe put a warning for it?). I'm happy the maintenance worker saw the bag move and informed others to get the help he needed. A human(s) did that to him, but humans also saved his life. Not all humans are cruel, his owner was. I'm glad that he has a wonderful family now and can live out his life the way he's meant to.
