Boxer head bobbing syndrome

This is hard to watch, but I'd like to put it out there in case it will help put anyone else's mind at ease. Our young boxer started bobbing her head uncontrollably out of nowhere. It ebbed and flowed for several hours.

Of course, when we arrived at the Emergency Vet, it stopped, and then started up again when we got home. It's happened only once, and the official diagnosis from our vet and the ER vet is "idiopathic dog head bobbing syndrome." It is not a seizure.
