Of course, and none from rescue groups (who see a disproportionate number of deaf whites - far higher than 20% in many cases) since I've yet to see a rescue that's qualified to make any statements whatsoever on the genetic cause of deafness in any dog.
You would do well to read the work of Drs Strain and Cattanach - both mammailian geneticists who've studied and documented the causes of deafness due to lack of pigment (and, since that seems to be important to you, so far as I'm aware neither are associated with any rescue groups anywhere in the world
). Both have done substantial amounts of work on the impact of the extreme white spotting allele of S - sw, which is what causes both white markings and deafness in this breed, and a few others. You can start here: http://www.steynmere.com/DALM_DEAFNESS.html

And once you've done that - and IF you understood it - then you won't be making statements like this...
BTW whites don't lack pigment only albinos do. Whites may lack the pigment cells in the inner ear and that is what makes them deaf.
"White" is most definitely lack of pigment. It's not just the inner ear that melanocytes are missing from either. Do you happen to know what the effect
of lack of pigment on internal organs is? If so, there's a scientific community waiting to hear it. Or you'd rather go ahead without that knowledge, and damn the deafness issue to boot?
As for breeding of flashy dogs - that has been addressed many times on this site, including earlier in this very thread
Go read that - we don't need to repeat the same information over and over because you haven't bothered to read the whole thread.
