Yes you can register with AKC as a parti, you just can't do it on the written/printed reg. paperwork that you send in. With Saleen I used the AKC's new online registration and when I got to the part where I specified her color there were tons more choices included partis and phantoms. I was surprised.Also there isnt a option to describe if your dog is a parti. All you can put is what best describes your dog. And yes, no parti poodles allowed in conformation events, just events like obedience and agility.
