First, primary epilepsy in a 12 week old puppy is very rare. Seizures usually don't start until a dog is 1-5 years old. In a puppy under a year, seizures are usually a symptom of an underlying disease.

These are the most likely causes of seizures in puppies:

LESS THAN 1 YEAR OF AGE

Anomaly: hydrocephalus.

Inflammatory:
Infectious - Viral: canine distemper; parasitic; bacterial; fungal
Immune mediated

Metabolic:
Hepatic - portosystemic shunt; Autoimmune thyroiditis (early stage: TgAA
positive); Hypoglycemia; Electrolyte disorders

Toxic: Single or combination vaccines; Lead; Drug related; Other exposures

Trauma: Acute; Delayed

Degenerative: Storage disorders

POSSIBLE CAUSES OF SEIZURES BY AGE

Since your puppy is a Yorkie and Yorkies are thirty-six times more likely to have a liver shunt than all other breeds combined, your vet was right to suspect that first.

Here is some information about liver shunts for you:
