i have a question about cerf

I am looking into a havanese puppy and I asked the breeder about the health tests done.She said she did all the testing done that hca recommends and sent me the numbers.It looks like its only for the female.Also I checked the number she gave me and under cerf it says e-1 lens,punctuate cataract,signifigance unknown.Does anyone know what this means and should the male have all the tests done too?

I'm not an expert, but as I recall, a punctuate cataract is a pre-cursor to a full blown one and they can either stay the same without problems or progress. Personally I would buy from a clear CERF dam and sire. And yes, they should both be tested in my opinion.

Well, the words "significance unknown" mean that the dog passed her CERF and got a CERF number, and they don't know how it will impact her later. Can you get any more information on where it is on the lens?

A lot of people get freaked out by the word "cataract", but it doesn't necessarily mean anything bad will ever develop on the dog's eye when used on the CERF reports.

Can you get more info on the sire too?

I would say yes, the sire also should've been health tested and passed. Half his DNA is going into your new puppy.

By the way, when I ask if you can get more info on where it is on the lens, all marks in the eye have to be noted on the CERF paperwork. They actually draw where the problems are in the eye, so the breeder should have a copy of that. You may be able to ask if you can get a photocopy and take it to an ophthalmologist to ask about it yourself. (There is at least one in Dallas.) Then at least you'll have an expert opinion on how it may or may not be a problem.

I have no input on your CERF, but i wanted to commend you for doing the research. It is way too easy to fall in love with a puppy--tested or not!!!

Much is made over "Punctate Cataract-significance unknown" by some people but it really depends on the experience of the Opthamologist. We took our dogs to a closer, more convienient vet than going down to Raleigh to the NCSU Vet school. The vet was young, and possibly with an agenda, and noted "punctates" on a couple of our dogs. We took them back down to NCSU to the Opthamologist with over 30 years of experience looking in animals eyes and he said it was "nothing". We took them back to get their CERF's this year and got "normal" with no notes of any kind at NCSU. That's why I posted Belle's CERF this year in the gallery since much was made about our dogs having "health problems" in one of the long HSDAA threads here. That pic is the paper that you get back from the vet and you can see what the form looks like that you get back from OFFA in Melissa's Havanista thread about her new website.

I'm not saying that it doesn't mean anything ever, but it seems like that comment can mean many things including that the vet just doesn't know.

I'd go by the breeder's history, how well they know their own line, reputation, and guarantee. And of course have any dog checked every year. This seems to be a hard thing to get people to do. When we first started breeding, Juvenile Cataracts were the only thing that Havanese people publicly worried about. Our guarantee said that we would pay for any cataract surgery if the new owner did CERF's every year. I think we maybe had two people to get CERFs done and even those stopped after a couple of years. We have dogs up to eleven years old who all still have clear eyes. We still recommend that our puppy owners get CERFs done but I don't think hardly anyone does.

Both parents should be fully health tested to their age. If they are under two, then they should have eye cerf, patellas cert., cardiac, baer testing and prelim on hips. If two or older then they should have the OFA hips, elbows and legg-calve-perthes in addition to the above tests done.

I think there are many times when we are told that the word 'cataract' implies that the dog will be going blind in the future. However, that word, at least when it comes to the CERF testing & results, doesn't necessarily mean that. You have to know where it is on the eye and any other comments that are noted. That is why I encourage people to talk to ophthalmologists to get more information.
