The OP stated that the Bile Acids and amonia levels were tested and came back normal or non conclusive. The pup is taking Lactulose, orally and was given an enema with it and is/was on antibiotics, and there was no change in the pup's symptoms. This tells me it is
not Liver Shunt, as these meds would have helped if it were LS.
The pup was started on Prednisone when he was diagnosed with an ear infection.
I do not diagnose, but there are situations where specific symptoms and diseases need to be looked at because they are deadly if they are not diagnosed and treated in a timely fashion, and with the appropriate medications. The neuro symptoms described here need to be evaluated quickly, because
if this is any one of these diseases: AAI, Chiari,
Syringomyelia, GME, or NME, this pup is in critical condition and treatment needs to happen soon.

I am not trying to play vet here, but these symptoms are red flags for these diseases, and as they are relatively difficult to diagnose, and not common nor associated with this specific breed, many times an owner will have to mention them to their vet. My vet even said when they see Yorkies, they see ' Yorkies=Liver Shunt'. This is because Yorkies are genetically predisposed to developing Liver Shunt, and when nothing else is evident, they will look at the liver.
I am not saying vets are bad or incompetent. Occassionally, vets miss things, it happens. It doesn't mean that they are not still good vets, as good vets learn from their mistakes.
