One other thing. AKC did pass allowing clubs to add "All American Breed" (mixed breeds) in some of their venues. You do have to get a number from the AKC which requires you to pay them money.
Some club venues will state that they are not supporting mixed breeds at their shows. You have to go to Info Dog to find upcoming AKC shows and events, closing dates, entry fees and if mixed breeds are allowed at that particular show.
As you can imagine, the addition of mixed breed dogs to venues is not without contention in an organization with a mission statement that supports pure bred dogs and breeding.....
I recommend that you anyone interested in showing get a rule book (you can download it as a pdf from AKC website) and read it. Over and over.
