Interesting article.. however if you read the comments below the article you'll find this :

As a long time employee at a veterinary clinic, I have seen just as many or even more unhealthy mixed breed dogs as purebred, so the belief they are healthier is a myth. In purebred dogs it is just easier to predict specific problems due to their smaller gene pools. Mixed breeds also exhibit a much larger variety of health issues than is typically seen in purebred dogs.
In Padgett’s book, “Control of Canine Genetic Disease”, there is a list of dog breeds, including mixed and their identified problems. Mixed breeds top the list for number of problems with at least 220. The next highest on the list is poodles which have 145 problems and cockers 116. Still a high number, but still far fewer than mixed breeds. A great many mixes include crosses to poodles with one or more other breeds, so the risk for something going wrong in dogs with this sort of pedigree is even higher. More often than not, there’s no health testing or pedigree history and no breeder to consult, so mixed breeds may suffer longer or have to go through much more expensive testing to correctly identify their problem before they get adequate treatment
In spite of all the negative hype, inbreeding is only a problem when breeders fail to health test their dogs, research pedigrees and share important health information with one another. A truly ethical breeder is committed to their breed, is willing to openly discuss health issues in their breed and does all they can to provide healthy canine companions not only for the show ring, but as loving family companions.
One more note. The article talks about severe combined immunodeficiency (SCID) in some breeds, but fails to mention that this problem has actually been eliminated in cardigan welsh corgis through the develoment of a DNA test and responsible breeding. PRA has also been nearly completely eliminated in cardigans through the same method and the newly available DNA test for DM (degenerative myelopathy, also known as ALS or Lou Gehrig’s disease in humans) will provide many responsible breeders with the means to eliminate this debilitating problem from their dogs over time.
Further, the research on these and other disorders, funded through organizations such as The Canine Health Fund will not only help dogs, but will also help to provide benefits for humans with similar health problems.
