When anyone has a personal experience so dramatic as losing a puppy to the test, or having a puppy with liver shunt, their opinions are going to be biased in that particular direction. That's why scientists do statistical testing on this sort of thing. With enough information they can say if the risks outweigh the value. They would have to determine how likely a death would occur through the testing procedure, and if the test results are truly valid in a puppy that young. Testing a puppy who shows no symptoms, and especially with parents who have been cleared seems like an unnecessary risk. I would much prefer a breeder thoroughly knowing the background of the pups, such as parents, grandparents, and so on, although it can still come up, the probabilities are much lower. |
