OFA problems.....

[Sound Bay Newfs]

Many long time breeders have told me, Jennifer, that OVC is a red flag - the presupposition that the dog wouldn't have passed OFA...

I have thought the same, but the fact that the dog can be evaluated earlier than OFA, seems attractive sometimes. Then if the films are then sent to OFA, all bases are then covered, it would seem. I questioned my vets office about OVC one time and they said they have never worked with them.

The only drawback really to OVC is that the don't have the database that OFA does. It's nice to be able to search on the OFA site for vertical pedigrees etc.

 

[Sun Valley]

Your right Cindy!

And they are now returning your results to the Vet who did the x-rays and not the owner. I know years ago they were returned to the owner.

I also checked the box for publication on their web sight, but they never published it.

But if you are applying for a CHIC # - than all of the results ARE captured on the OFA website....

If the films were taken before the dog was 2 years old, you only get a prelim evaluation if you send them to OFA for evaluation.

OFA will register the OVC results for a fee. This not a re evaluation of the same xrays.

Why can't you send the same xray for re evaluation?

You can send the same rad film in for evaluation--I've done before. OVC certified for the first go around and once I received the films back from Canada, I completed the OFA form for a 'prelim' evaluation as my girl was only 22 mos old and submitted the films to OFA. At 22 mos of age, I had what would probably be the 'official' OFA evaluation. So I had both OVC and OFA's opinion on the same radiograph. Submitted the OVC report to OFA to complete the CHIC requirements. Done.

My guess would be that they dont allow reuse of the same XRAYS because it might "open a can of worms" so to speak. One of the disadvantages of OFA is that it is a subjective way to grade hips. If you started having different groups of Radiologists giving the exact same XRAYS different grades, it would raise a lot of questions about the integrity of the program altogether. It happens now, with the same dog getting different ratings, but at least they can say they were looking at different XRAYS.

 

[Ginny]

As said, you can have the same films read by OFA and OVC, but OFA won't reread films submitted to them earlier. A vet I know resubmitted what he considered poorly read films and got an entirely different reading the second time around. He told me he did this several times. Once OFA realized what was happening and ended up with 'egg on their face', they made the ruling of no resubmissions. So I've been told...

 

[Ginny]

From my past experience with OVC, they were actually very insightful. I have no qualms about submitting rads to them and have done so a few times over the years. I wonder, Ginny, if these breeders don't like the fact that there is no grading-just a simple pass/fail?

Maybe, but I was told that with OVC it's easier to get a 'pass' and those, with what might be borderline results, would be more inclined to use them. I'm just telling you what has been told to me. I have zero experience with OVC, but may consider using them in the future.

 

[Sun Valley]

Through the years I've had a few hips come back from OFA with a borderline...when they were resubmitted they all passed with a good rating. I also didn't wait as OFA recommends, but sent them immediately.

With elbows, I have been told and shown via diagram by a Newf breeder/Vet as to why OFA won't pass them because of DJD but OVC will. OVC appears to look at the elbow joint only while the OFA looks outside the joint...if that makes sense?

What I've been told is OFA usually fails if there's an abnormality in the x-ray and OVC may pass depending on what the abnormality is. I had friends submit and on one of mine the abnormality failed the hip(s) while sending to OVC may have passed the hip(s). OVC only gives the pass/fail. There are times you may have to go back to better hips than what you have currently and OVC only says normal vs excellent/good/fair.

 

[Sun Valley]

Janice,

If OVC won't certify hips or elbows they will tell you why.

You can send the same film but if it was taken on a dog under 2 years old at the time of xray, you will only get a prelim evaluation from OFA.

When we had our problems with Zeus's OFA being so different than his PennHip rating, we were told by OFA that we would have to resubmit a new XRAY. They refused to re-evaluate the first one, and he was 5 at the time.

I believe Windancer was asking why you couldn't send the same xray to OVC and then to OFA.

Yes, OFA will tell you they won't reevaluate the same xray that they have already evaluated, you must send new xrays if you want them to reevaluate.

Sorry...I thought she was asking why they wouldnt reevaluate the same XRAY using a different set of Radiologists

 

[Windancer]

What I was saying was...if you sent a digital to OFA...why can't the vet send the same digital to OVC? They keep copies...I was respondong to someone who I thought said you could not do that..

 

[dee]

You should be able to do just that, Julie. And with Digital images, should be even easier to do since the vet can make multiple copies of the disk or maybe even send via email.

You can do that - What I was trying to say say as that - If those xrays sent to OVC were take when the dog was under 2 years old - OFA will only give a preliminary evaluation. So if you still want an OFA number, you will need to re xray after the dog is 2 years old.
