Puppy Eye Folds and Dwarfism?

[HiRollerlabs]

Thank you everyone for the information.

Reading the information on Optigen that even carriers of the gene may develop eye problems in their lives, are people who have pups with folds doing the additional OD test to rule out folds associated with RD and dwarfism? Do people realize that carriers (not just affecteds) are at risk? I didn't until I read and then reread the information on Optigen.

Somewhere in my files one of the service dog organizations had reported incidents of folds appearing AFTER the 7-8 wk puppy CERF (and some puppy folds disappearing after 16 wks or so also). This led to the annual CERF recommendation for Labs, etc because they'd send their pups out to puppy raisers at 8 wks, only to get the disappointing news upon their return to the school at 18 mos and find folds that weren't there prior. Obviously after spending a lot of money on that pup in the raiser's home. So there are definitely different types of folds and different timing of appearance and possible disappearance.

I tend to do my litters right before they leave (so at or just before 8 wks), and my own keepers get on an annual check from there on.

Yes Anne, a number of carriers will have eye issues.

I had a pup pass the 7 week CERF.
Took her back in at one year and she showed a fold.

Did the test and she's a carrier.

She is spayed.

OK I am thoroughly confused.

When is the best time to do the first Cerf exam on a puppy?
