Hi
Can anyone tell me in a simple form what a fair hip rating means ?
Can anyone tell me in a simple form what a fair hip rating means ?

It means the dog is not dysplastic, but the hips as evaluated one xray by 3 different orthopedic vets are not as well formed as hips that are Good or Excellent.

Exactly. All things being equal, one would want to breed to the dog with excellent hips. But, "fair" is ok, particularly if the dog brings a lot of other qualities to the table. It does not mean "unbreedable." Also, remember that even with the OFA ratings, it is still a crap-shoot. My first schutzhund dog was a bitch whose father's hips were "fair" and the dam (unbeknownst to me until my bitch was 3) had one hip that was severely dysplastic. My bitch had one good hip and one excellent hip, and ended up with a "Good" OFA rating. Go figure. It could just as easily gone the exact opposite way.
The director of OFA at the time told me that she had "very, very good hips, for a German Shepherd." I couldn't talk him into a Good/Excellent rating, though.

OFA says fair is still normal.
In the old days it is just normal.
From OFA, fair is comparable to normal in SV, not fast normal. Fair is comparable to FCI B1
OFA Borderline is comparable to SV fast normal.

I have seen dogs with SV fast (near) normal receive OFA "Fair" and "Good."

The skill of the vet can change a grade.

Per the OFA website...
"FAIR" is listed as follows:
Fair: Assigned where minor irregularities in the hip joint exist. The hip joint is wider than a good hip phenotype. This is due to the ball slightly slipping out of the socket causing a minor degree of joint incongruency. There may also be slight inward deviation of the weight-bearing surface of the socket (dorsal acetabular rim) causing the socket to appear slightly shallow. This can be a normal finding in some breeds however, such as the Chinese Shar Pei, Chow Chow, and Poodle.

Edited to add: As mentioned by others, "fair" is still an acceptable rating with respect to "passing" OFA (as opposed to being borderline or dysplastic, which are not passing ratings).
Regards,
Diane

The OFA also says:
Do not ignore the dog with a fair hip evaluation. The dog is still within normal limits. For example; a dog with fair hips but with a strong hip background and over 75% of its brothers and sisters being normal is a good breeding prospect. A dog with excellent hips, but with a weak family background and less than 75% of its brothers and sisters being normal is a poor breeding prospect.
OFA's Recommended Breeding Principals
1. Breed normals to normals
2. Breed normals with normal ancestry
3. Breed normals from litters (brothers/sisters) with a low incidence of HD
4. Select a sire that produces a low incidence of HD
5. Replace dogs with dogs that are better than the breed average

IMO, 4 is hard to know and 3 is even harder.
Only 1, 2, and part of 4 , and 5 are meaningful.

re: 3 different orthopedic vets by blackthorne, not so much...
the offa takes the plates, makes digital images of them, then sends them to REGULAR vets who are randomly chosen each time for their review.
which is why NOT to use the OFA... for Xrays, as there are too many biased country bumpkin vets who see the breed "GSD" and their heads spin turn and go on auto pilot and ck off fair or fail. You're lucky to get a approval from the OFA
use the SV only
