All of these acronyms (and many more) are common in the purebred dog world. If you want a healthy, registered, smart, purebred puppy, you should learn what these letters stand for before you buy, otherwise when a breeder says proudly, "The sire of these puppies is OFA Excellent, has his CDX and TDX, is CERF cleared and went BIS last week!” you won't have a clue what all this means. Some of these abbreviations are very important, because they show that the breeder is doing all the proper health clearances on his or her dogs before they are used for breeding. Of course, even healthy parents sometimes produce a puppy affected by a genetic disease, but ensuring that the parents and grandparents are cleared of the major disorders common in that breed increases the likelihood that the puppies will be healthy, too.
