I send out my sample to test my pug Felix for the PDE test to see if he was clear, a carrier or had two copies of the gene and it came back Clear!!! I'm so happy about the results and glad they came out with some sort of testing to enable breeders to try and wean out this horrible disease in our beloved Pug Dogs. I wouldn't want any of my puppies to fall subject to disease. Here is the test link if your thinking about getting your pug tested. I encourage all breeders to test there breeding stock.
