I am buying a 4 month old puppy with PPM and it is bad enough that he has a cloudy blue eye. It is from a reputable breeder and the eye doc says both eyes are visual and should improve with age. I'm just wondering if anyone out there has had a dog with blue eyes as a puppy. He has iris to iris, iris to cornea, mad iris sheets, especially in the one eye. I just don't know what problems could pop up down the road and wonder if anyone else has any experience with adult dogs who once were as severe as this one.
