A seizure is a sudden, uncontrolled electrical disturbance in the brain. It can cause changes in your behavior, movements or feelings, and in levels of consciousness. If you have two or more seizures or a tendency to have recurrent seizures, you have epilepsy. There are many types of seizures, which range in severity.

Symptoms can include:

• Collapsing.
• Jerking, muscle twitching.
• Stiffening.
• Loss of consciousness.
• Drooling, chomping, tongue chewing.
• Foaming at the mouth.

Dogs can fall to the side and make paddling motions with their legs. They sometimes poop or pee during the seizure.
