Beaglemom had a good idea about videotaping it and posting here (or emailing one of us). Maybe we can have a vet look at the video.
In my very unprofessional opinion, it seems to be spinal, which will require a vet how ever you look at it. There has to be a vet in Romania somewhere. Even if there is a dog shelter you know of, they must have a vet there or at least can put you in touch with one.
