We did see an Orthopedic vet and he didn't even bother with x-rays. He checked him over (very roughly but they need to in order to find where the pain is coming from) and determined
it was in his right elbow. Said it can take up to 6 weeks to heal provided he's resting most of the time.
We were only allowed to take him on short bathroom walks. No playing, no running, nothing. Rest and 50mg of Rimadyl twice a day.
If two weeks later on the re-check he didn't show any improvement, then they were going to x-ray.
We went back and while he was still limping, he barely showed any pain at the next exam. So back to Rimadyl and rest. This time 50mg once a day for 2 more weeks.
In total, I had Wellie on rest for over 6 weeks but he's fine now and there hasn't been any limping in over a month.
I think the rest is even more important than the Rimadyl.
There's really no way around it, you have to keep her calm. If she's really high strung, that may require crating. But whatever it is, it needs time to heal.
