A friend of mine had her dog done at 2 years. Result B/D (this is in Europe... B is ok, D is not good)
As the D was mainly because the hip was "loose" she decided to get the dog done again a year later to see if it would have tightened up.
Result D/D so even the good hip was no longer good!
I have to say this is the first time I have heard hips changing so drastically.
I have had my dogs done at 7 months and the pictures taken then and at 2 years have been the same (I took the puppy xrays with me to compare to the official ones that got send off).
Others I know say the same, hips are what they are and good hips should not became bad, until maybe when the dog is very old but this would be due years of use just like when we get old...
