I couldn't agree more.That is sort of how I read it as well. The DM test should be used in consideration although, should not be an end all for a breeding. If one stives to breed a clear x clear on everything we'll not have a single decent Chessie left. Our DM affected and carrier dogs have brought WAY too much to the table to be written off so easily. Weighing the merits and OVERALL quality of what the dog is passing along is of upmost importance. Generally speaking, I'd be willing to put a bet down that says that the overwhelming majority of our BEST field dogs are at minimum DM carriers. Are there exceptions? yes. Are there a lot of exceptions? no.
Too many breeders are using the DM status now as a scare tactic to unknowing buyers who don't fully understand neither the testing or, the disease. I've heard a breeder telling a person they shouldn't buy puppies who "have DM" and the only way to be safe is to buy a puppy from parents who are both DM Clear. People are using "half truths" because they are breeding two DM Clear dogs and not giving the new potential owners a decent understanding of how DM can be passed along and the differences between affected / carrier / clear........ This kind of misinformation is a detriment to the breed and giving new Chesapeake owners a start on the wrong foot.
With that being said, should someone be breeding a DM affected x DM affected? HELL NO>
