My Pug, Sophie, has focal seizures that cause her to become almost feral -acting terrified of everyone and everything, as if she doesn't recognize familiar people or things. Her vet told me this type seizure can manifest in many odd ways. Thankfully her episodes have decreased dramatically over the last couple of years and she never required medication for them. Just food for thought. I hope you find the answers to your sweet baby's odd behavior soon.

Hugs,
Leslie
