I though it looked like a sort of seizure. Alfie has seizures but he goes very stiff , mainly in his front legs , but if your vet ruled that out maybe its to do with her spine .I think there is a thread about a conditon to do with this somewhere, i will have look and post it if I find it. Good luck in getting to the bottom of what is going on with your little one.
