People can be so cruel. Dogs give us everything they have. They don't deserve a fate like the one these were rescued from.
I read a story a while back about the dog trade, racing in particular. It was here on Steemit. Let me find the link. It's told from the perspective of the dog. Absolutely heartwrenching. It's too old to upvote, so this isn't a play for that. I just think you'll like it. Very relevant to what you posted here.

Thanks for your comment! I read the story, it's so sad! :-(
