My dog had his rabies vaccine yesterday. He had a seizure today. Can the vaccine cause this to happen?

Oh no, I'm so sorry Riley had a seizure! No, vaccines do not typically cause seizures as a side effect, and I would be concerned there could be another cause behind it such as liver disease, diabetes, toxin exposure, or a brain tumor among other causes. I would have Riley seen by a vet for this, as it's important to diagnose and treat the cause of the seizure. If he seizes again before you seek veterinary care, do not put your hands near his mouth, monitor him to make sure he doesn't hurt himself crashing into any furniture, and seek emergency veterinary care if the seizure lasts more than five minutes.
