What are the Causes of Dog Seizures?

A seizure, also known as a fit or convulsion, can be defined as “involuntary contractions of the muscles, abnormal sensations, abnormal behaviors, or some combination of these events” that can occur in some dogs. A seizure is caused by the sudden and excessive firing of nerves in the brain.

Symptoms of dog seizures can vary from generalized signs affecting all parts of the body to focal manifestations that only impact part of the body. For example, a generalized seizure may manifest as a dog falls over, paddles all limbs, teeth chattering, foaming at the mouth, urinating, defecating, barking and/or other vocal behavior. A focal seizure can cause facial twitching only.
