I think its a good idea to test, even if the parents are clear, its like a double check and also goes on record so anyone can look it up. If everyone was more open it would help the breed. Some people over here don't even acknowledge that fanconi exists, others haven't tested maybe they are worried about the results. The majority do test though and nag others to do the same.
We do have some good dogs over here but unfortunately most of them have come back carriers or affected. I think you need a knowledge of what there is other than in the show ring today. I used an 11 year old to get the lines and qualities I wanted.
There are some promising pups out there and now that we have the testing we will have a lot more clear dogs to choose from in the future.
When the definitive test comes in I am planning to re-test.
