I do not disagree about the very serious nature of PRA.  My remarks were 
directed at Juvenile or late onset cataracts.  This condition (JC) rarely   
leads to disability except some minimal in very late life i.e. 10 years or 
so.  I speak only of Pyrs, I claim no knowledge of other breeds sequelae.  So 
I would probably concur with PRA.  To me there is nothing more serious than 
Dwarfism to the breed itself and that is not intended to diminish the serious 
nature of PRA that you speak of.  It, Dwarfish, is much more serious as it 
has infested the whole gene pool essentially, where PRA we might have a 
change to limit it greatly with early education and an open honest provision 
of information.

SAS sounds extremely bad as well and its inheritance mode of a problem.  What 
is the feeling of knowledge presently out there on SAS puppy, if both parents 
must be carriers?  Or can only one transmit the disease forward.  We really 
do not understand the nature of the transmission and I have read it displays 
both dominance and recessive qualities.
