I would contact the news/media.
A while ago, a reporter did 1 or 2 short episodes on this breeder and his kennel. I'm not sure where the thread(s) about that went but I know they're here somewhere. I'll try to locate them for you and post them here. If anyone can find those threads, it would be great to post them here (hint hint, wink wink lolol)
But maybe you can contact that reporter, tell him your story and that you have PROOF (medical information, vet bills, maybe get your vet to talk too, etc.) and see if he can help you out and maybe even do an episode regarding your situation.
I'm SO SORRY for your loss. I know what it's like to lose a beloved baby, so my heart goes out to you. I wish you all the best of luck.
