It's a lifelong condition and a rescue that I was a foster with previously had a few of these puppies as forever fosters. They came from a "breeder" n my area that breed many sick dogs without regard to the health of the puppies and continued to breeder indiscriminately. I believe they sold puppies on the internet at a place called PremiumBreeders.net but it looks like the site is now closed down. I so glad because there were some very sick puppies sold on that site that caused a lot of heartaches for buyers. I don't have much advice regarding this condition since I was not involved directly with their care but my suggestion would be to have your parents spayed/nuetered. This is very time consuming and emotionally draining. I wold be further concerned since this is the second puppy that you have that has a very large medical condition that you are dealing with.
