Has he had blood work done to check his Bile acids ? or an MRI to check for Chiari ? or an X-ray to check for AAI ? these are all very serious issues that yorkies are prone to & if your pup has any of these things without the proper treatment he will most likely die and have a very painful life till he does. I would do whatever you can to get some diagnostics done so he can be properly treated & if you can't afford to do this , then you need to find a reputable Yorkie Rescue to turn him over to so that he can get the help & treatment that he needs. I will be praying for your baby. The shaking of his head & screaming are not normal seizure activity & it sounds like it may be AAI or Chiari.
