Is there a time frame for resubmitting xrays to OFA?? Some have said you have to wait 6 months??
TIA

That is only because you will likely not see much change in under that timeframe on a growing dog.
I'm sure OFA and your vet will gladly take your money as often as you would like to give it to them though

The Radiology panel that reviews the x rays changes every 6 months. That is definitely one of the reasons to wait the 6 months.

First time I hear that. When do they change?

The panel changes every 6 months, so WAIT to re-do them, so you get a different panel of opinions. Who knows, maybe the new panel will be having a good hair day !
