I am not certain if Roy doesn't test any of his dogs now or what the case is. I am only aware of a couple males that have no certification by OFA or PennHip because they were looked at as breeding potentials.
Something that is often mis-understood in our breed is health testing is important and should be done, but that we honestly lack for a lot of "quality CC" that are healthy, correct and stable. So I don't rule dogs out that might not have outstanding scores or are even mild if I have an outstanding result in what I am looking to pair it with if the rest of the package is great. Our gene pool is still too small to be able to do that and not bottle neck in the short term. However, if choosing to do this it is imperative that anyone getting a puppy is well aware of this in advance so they can make the decision for themselves on if they want to take that risk with the breeder or not.
The PennHip vs OFA argument will be one that no one will ever 100% agree on because there are strong supporters for each side. Understanding both ways and the pros and cons so when you are getting results from either you are educated on what they mean is the best way. One thing to not is it is not an average with OFA it is taking the lowest score given, so if 2 say excellent and one says fair the dog get the fair rating. That is what was told to me when I contacted them in regards to the results on a dog I had done (was also done PennHip).
This breed is also a stoic breed so there are some of the nicest dogs that have failing hips that in their prime you would not know without the xray (as they age is it more apparent with arthritis setting in) and there are some dogs that have good hips that just move like shit. I doubt that is strictly a corso thing as I suspect most mastiff breeds tend to be stoic.
While it would be nice for those in the breed to stringently test, getting those to test hips seems to be a trial. Elbows less often and hearts, I won't even get into the number that don't even bother with that. Also until lately an auscultation from a GP was sufficient to have a heart certified which can be misleading as they are not specialists and can miss things.
There are no black and whites when it comes to messing with genetics and while we can always hope that when putting 1+1=2 we often find that mother nature has her own set of rules she plays by, and you learn to roll with the punches.
