Dog Epileptic Seizures

Canine epilepsy refers to dogs that have seizures that happen over and over again (called recurrent seizures). Dog epilepsy can have a known or unknown (idiopathic dog epilepsy) cause.  Most dogs that have epilepsy have canine idiopathic epilepsy.

It is possible that a dog can experience seizures without a known cause. This is referred to as Idiopathic epilepsy. It tends to appear in dogs between the ages of 1 to 4 years. If seizures appear after 4 years, that this cause is ruled out. Breeds where idiopathic epilepsy appear more often include:

Dog epileptic seizures tend to increase in frequency over time.  Each seizure needs to be similar in nature in order to be considered epilepsy.  

When a cause is identified for the dog epileptic seizures, it is sometimes some type of brain injury such as scar tissue.  

A dog with epilepsy may not have a classic seizure, but may show other odd behaviors which is referred to as a canine psycho motor seizure. These behaviors include barking in a frenzied state, licking its body, chewing the body, staring out into space , or snapping at invisible things.

The goal of treatment for dog epileptic seizures is reduce the frequency of seizures and the severity of the canine seizures. Dogs that experience more that 2 seizures in a month or 10 to 12 in a year are treated.

Stages of Canine Seizures:

Dog seizure pass through different stages;

  • Pre–seizure: This stage is also called “Aura”, in which the dog may appear restless, pacing, seeks shelter, seeks affection and hides minutes before actual seizures.
  • Ictus: This is a true seizure, in which the dog becomes excited and vomits, salivates, runs in a circle, collapses and has severe uncoordinated muscular activity. In partial or less important seizures, this stage lasts no more than 5 minutes.
  • Post–Ictal Seizure: This is the recovery stage from a canine seizure, in which a dog may become blind (temporarily) and appear disoriented and uncoordinated. This stage of recovery may last from several minutes to days and weeks.
  • In the second stage, or true seizure, it has been noted that uncoordinated and uncontrolled muscular activity is a major symptom, which can affect almost all muscles of the body including the anal muscles.

    In this stage, it should be remembered that patient has no control and awareness of its whereabouts and in-voluntary bodily actions. Therefore, the patient may not respond to any commands and any past training efforts.
