Can someone explain what the difference is or is EFS a type of seizure? I was watching a video of a cavalier on a FB group and she would run her head and then lay on her side. I think the owner said she has seizures. I googled some videos and to me this seems seizure related. Very sad but I am glad there is now a DNA test available.
