Seizures, also called epilepsy, occur due to sudden, involuntary bursts of electrical activity in a dog’s brain, explains WebMD. Twitching and uncontrollable shaking are typical symptoms of a seizure, and they can last from seconds to several minutes. Other symptoms include jerking, stiffening, collapsing and loss of consciousness. A dog that drools, chews its tongue or foams at the mouth may also be suffering a seizure.

The grand mal seizure, where there is unusual electrical activity in the entire brain, is the most common type of seizure, states WebMD. Another type of seizure is called a focal seizure, where abnormal electrical activity affects part of the brain only. A grand mal seizure involves convulsing and losing consciousness, whereas a focal seizure causes bizarre movements in a single limb or side of the body. Other types of seizures include the psychomotor seizure and idiopathic epilepsy.

A dog owner should stay calm, slowly slide her pet away from any furniture and stay away from the animal’s mouth to avoid getting bitten, suggests WebMD. It is crucial to call a veterinarian immediately once the seizure ends.
