Yes, dogs can suffer from epilepsy. Dog epilepsy is a brain disorder, in which there is haphazard activity of nerve tissue. This leads to abnormal nerve transmission.  Repeated seizures in dogs are not just one disorder or syndrome. It includes many disorders. Dog epilepsy is either idiopathic or symptomatic.

In idiopathic epilepsy, there is no other brain abnormality that can be identified other than seizures.  Due to genetic reasons, idiopathic epilepsy is common among breeds like Labrador Retriever, Collie and British Alsatian. 

Symptomatic epilepsy is presence of some brain abnormality which is identifiable. This condition of the brain triggers seizures. It is vital to understand the term seizure. A seizure refers to involuntary contraction of muscles. This may lead the dog to drool excessively, urinate, clamp the jaws and run.

After this, the dog becomes motionless for some time. It is worth noting that even though it is commonly seen among a few breed of dogs, it can affect any breed. With proper treatment the dog’s life can be prolonged. However, as compared to a normal dog, a dog with epilepsy lives less. Treating epilepsy doesn’t cure the dog completely. The main goal is to control seizures.
