Totally agree! This video scares me!! I've seen people with this type of movement but never a dog!oh goodness!!! Get her to the VET TODAY with that video. That is NOT right. That is something neurological going on, perhaps a type of seizure activity. Oh please get her to the vet. I would consider this very close to an emergency situation. Be sure and bring the video so your vet can see it for himself when he gives her an exam.
