FWIW Liver is one of the genes that seems to have a high % of PRA carriers/affected.
Not necessarily 
. I have 2 chocolate roans who are the product of a Clear to Carrier mating. I have just had them Optigen tested and both are Normal/Clear 
Yes because you did a mating from 2 Optigen tested dogs, so were only going to produce A's or B's in that litter. What I meant was people who had dogs tested when Optigen first came out, now it won't be the case as people are making informed decisions based on the testing available.
This is why even though we won't breed from Bracken I would like to get her Optigen tested in the future to see whether she is affected/is a carrier...
Hmmm never thought about this before - but I can see what you mean Emily
I plan on getting Braan neutered when he is older, but may consider having this test done for my own personal curiosity, as I don't know much about the breeder he came from originally (due to him coming to me via a different route
)
