I have a bitch who will be two this month. She is in heat now. Looking for opinions on long after a heat should I x ray her hips and elbows?

Thanks in advance.

I xrayed on a silent heat and they came back good. After the Vet did the xrays he tested her Progesterone.

I've heard they can be one grade down in heat. I won't re-test for an E rating, good is fine and I don't know for sure it will change.

The OFA advise is to wait 4 weeks after she is not in heat anymore. I've got excellent hips done while in heat, so not all bitches would be affected by the hormones.
