I wonder if any of you can help with some advice. My beloved pet Boston died a few weeks ago aged 11.5 from complications with her heart. In the last two years of her life she also became almost completely blind from a worsening cataract condition. I really want to get another Boston puppy but I want to do all I can to try to mitigate the known cataract problem in the breed. I have seen a puppy from a reputable Kennel Club breeder and both the Sire and the Dam have had the hereditary HC-HSF4 DNA test and passed. The problem I have is that the Sire has had 4 additional BVA/KC/ISDA eye examination screenings, the first 3 were clear but the fourth at aged 8 in February this year shows that he is HC "affected". So now I am completely confused and not sure what this means and if I should find another puppy instead. Any advice or help would be amazing...the puppy is gorgeous and I have fallen in love but want to do the right thing.
