From Warning Signs to Prevention: Navigating Dog Seizures

6. What Causes Seizures?

There are too many possible causes of seizures in dogs to list. Seizures are roughly divided into two categories: Intracranial and extracranial. Intracranial causes are ones that exist within the dog’s skull, which point to epilepsy, genetics or conditions such as brain tumors or encephalitis. Extracranial seizures are caused outside of the skull and can include poisoning, direct trauma to the head, metabolic disorders or “something they ate,” such as chocolate.
