I really need to know, is cherry eye hereditary in dogs? You see, I had a small adorable litter of puppies and when finding them new home, I guaranteed that the pups would not have any genetic issues.
However, one of them developed this problem even though no others in the litter did and neither parent has any eye problems. So while I thought that I knew the answer, I can't find a clear solution to the question of is cherry eye is genetic? I have asked others owners and I have asked my veterinarian, but he is less than helpful when it comes to this one.

First, we do wish to commend you for being responsible for your puppies and having a health guarantee given to each new owner.
The question of “is cherry eye hereditary” can be a bit tricky and here is why… Even if BOTH parents have been cleared for eye issues, IF BOTH parents have a RECESSIVE gene for eye disease (it will not be picked up via testing), there is a 25 to 50% chance that the puppy will develop an issue. It should be noted that if a puppy has a white eye rim or both rims are white (pigmentation is not present), the odds increase.
Therefore, while it cannot be proven that this particular puppy developed this issue due to genetics, it IS possible that this one puppy developed the cherry eye issue due to both parents having a recessive gene.
If you had the proper eye testing done prior to breeding, it is not your fault that the pup is having an issue that would have been impossible to detect beforehand since it was recessive in both parents (dam and sire)...but with that being said, if your contract stated "any genetic issue", technically, there is up to a 50% chance that it is.
We would suggest taking care of the matter to maintain your reputation, and if you plan to bred any more, we would recommend revising your contract to omit responsibility for cherry eye due to the fact that it may or may not be genetic, as you have no control over recessive genes and the chances of it being genetic are 25 to 50 percent.
