Found these ones listed too...
ACHC = American Canine Hybrid Club
DDKC = Designer Dogs Kennel Club
DRA = Dog Registry of America, Inc.
My original point was not to compare the CKC in Canada to the USA CKC. No comparison. My point was to say with "lay" people or the regular public at large most do not even know what papers are the right papers. I spend alot of time with my perspective puppy owners and most do not even know what registry means let alone which one is the REAL one. Frustrating to me at times. So when the OP was asking about AKC vs CKC I am pretty sure she meant the USA one however the clarification was not made and the OP has not posted since I do not believe. Sorry to my Canadian neighbors, I was not meaning to put down the REAL CKC.
