Hi all. Our Russian ham Paul (a rescue, campbells colouring but likely a hybrid) is around 18 months we think. Today we noticed that he has 'dips' near the back of his spine. He's always had a bit of a hunched back since we got him - likely from too small a wheel when he was little. It's come on very suddenly so seems more like injury.
Here's a video of him:

Any idea of what could cause this? Could it be a stroke or leg injury? It seems structural and possibly his back legs. He's still sociable with a good appetite.
Note: we are trying to get an emergency appointment for today!!
