Some of our breeders may be along shortly to give you ideas on what the AKC can or will do but I'm thinking the only thing would be revoke registration on dogs illegally registered.
My suggestion would be to take the breeder to small claims court. File complaints with the USDA for poor breeding practices too.
Put some reviews on rip-off reports online where you can use her full name, including kennel name.
If you can win a court case the case becomes a matter of public record.
I'm just wondering, she forged signatures right in front of you? What did you do at that time?
