Vaccination shouldn't follow illness or surgery, ever.
Parent: "My pug was spayed and vaccinated a few days before this all (circling, drooling, had watery eyes, and showed signs of torticollis started."
Integrative vet: Considering the time between her being vaccinated and the onset of neurological problems, I would suspect she has a vaccinosis, an adverse reaction to whatever vaccines she was given. It is not advisable to vaccinate an animal that is ill or subjected to the stress of general anesthesia for any major surgery, such as spay/neuter. The vaccinations should have been done three to four weeks before or after the surgery, but for the sake of convenience, this protocol is not always followed.
