No large scale orgs that I know of. Our local bar has an attorney who does work against it, she has her number at the jail where other inmates will pass her number around if some mentions their dog, and intake officers will often suggest to inmates that if they have pets to call her. She is absolutely the most hard core lover of dogs I have ever met, and she will literally drive/run into danger to get to a canine to get it to a local non-kill shelter.
