    Default OFA Retesting

    I got a call from a friend today who had a dog come back with mild dysplasia results. She wasn't sedated for her x-rays. Just curious - how many of you guys have re-sent new x-rays (or even the same ones?) and gotten different results/better results?

    Their vet gave em a look beforehand and said they looked good to him, but I don't know anything about his credentials in the department.

    I had my dogs elbows retested and submitted a year after I received a failing rating. Used a different vet with more experience. Received a normal rating the second time. I have been told positioning is a major factor in the rating you receive. Only 1 opinion but it worked in my situation.

    I would tell your friend to take the dog to a vet who sedates the dog for the x-rays most likely gonna come back with different results. To many cases where unsedated dogs get x-rays and later get them redone sedated and end up with better results. Doing the X-rays without sedation is a waste of money in my opinion.

    This article about the importance of positioning is pretty good:

    http://leerburg.com/hipart.htm

    It has an example of one dog with poor positioning receiving a poor OFA score, and then the same dog with better positioning receiving an acceptable score. It also has hints about how to tell if the positioning is correct for the xrays, which may help your friend evaluate whether positioning was a factor or not. This is assuming that the vet who did the xrays is of no help.

    There's always a chance, OFA ratings are subjective. OFA x-rays and positioning are so important that you need to go to a qualified vet-xray tech who specializes in OFA to take them, one who is familiar with their ratings. Most of the time an OFA vet, will not even let you send them in unless they are sure they'll come back passing. If the films are iffy they'll usually tell you to come back and retake later, before they'll submit them. Could be a variety of reasons the results came back MD (positioning, subluxation, dog hasn't reached full growth). All I know is the vet that has done my OFA's always has a prediction on the rating and is always right. Might be because she used to do the evaluations-results for the OFA . Both times she was worried about the x-ray (1. subluxation of a bitch who was due to come into season) (2.A larger male that hadn't finished growing @2yrs.) She told us to come back and retake, the later x-rays turned out better and both received passing results. I'm glad she refused to send in the first x-rays.

    My first Lab was sedated and came back dysplastic. I went to a different veterinarian, x-rayed her without sedation and she came back good.

    I have never sedated since and all of my dogs have come back good or excellent. However, my doc works really hard to get proper positioning even if he has to shoot several times.

    My dog came back indeterminate, sedated. It said send new ones in a few months, which I did, fully sedated, they were almost identical. On the ofa site it says if no changes, they will be rated fair. When I got the results, she came back mild. I called ofa, spoke to one of their vets and they said well we didn't like her right hip and even through there were no changes, we rated her mild. I was kinda annoyed because they didn't follow what they said on their website. She was 60% on pennhip. LDI=.29; RDI=.42. Mood point now, because she died prematurely but it made me feel like offa was even more subjective than I had already thought. I'd rather see penn hip.

    My Shiba Inu came back dysplastic. We re took them a couple months later and she came back with a good rating.

    I sedate all of mine, always have (for 17+ yrs now). Not once argued w/ what the xrays or vet said. I think it has more to do w/ positioning where these conflicting results arise. On the other hand, you can't make bad joints look good.

    . Very true statement, but you can make good joints appear to be bad. Find a vet with experience taking, evaluating, and submitting to OFA.
