I don't know what to tell everyone. Contact the AKC, the BOD, and ethics and grievances with your complaints. I can't help you with this.
As far as I know Karin has never titled a dog in any sport, as far as I know she has never even completed anything she started. Yes her excuse for Castleguard's Maximus not competing was because he had DCM and severe allergies to everything grass and food being the main problem.
As far as Amore' goes, I do know that Dave works his dogs all the time they are very impressive corsos. As far as the main sport the kennel prefers you will have to ask them. They are one of the few kennels to prove themselves in the corso community.
It's sad when they have to refer people to other forums so people can learn about the working corso because the CCAA working chair has run people off. But that's just par for the course. Expect nothing less.
