My breeder wouldnt subject her dogs to that, so I guess I shall find out.
I don't think any of the tests are particularly horrendous - blood test and an eye exam aren't exactly "subjecting" the dogs to anything terrible. Both T's parent have been health tested, but I would have to have a look at their paperwork to find out exactly what for, can't remember right now (definately PRA though).
Personally in Australia it doesn't cost anymore to buy a pup from a testing breeder than a non-testing one so I would always go for the parents that have been tested. Why take any risks!
