Unfortunately, this is one of the major possibilities when Yrokesi present with neuro issues like that.
You would do the blood work. If the bile acids test is off, then you would go see a board certified internal medicine specialist for the next step. If the blood work is fine, this would probably be considered a neuro disorder and you would see a neurologist. Follow the vet's advice until you get blood work results. I'm very sorry. This is not uncommon in Yorkies.
