4 Signs Of Epilepsy In Dogs

Epilepsy is a disease that is characterized by recurring seizures. Some dogs have sporadic and mild seizures, while others have severe seizures that last a long time and occur frequently. Because seizures come in so many forms and can be caused by a number of diseases, it can be hard to determine whether or not a dog has epilepsy. Recognizing the four primary signs of epilepsy can help

1. Seizures

Seizures can take many forms but all are caused by abnormal, involuntary electrical activity within the brain. A generalized or “grand mal” seizure is the most dramatic because a large portion of the brain is affected. Dogs undergoing generalized seizures will fall down, paddle or stretch out their legs, may urinate and/or defecate, and are totally unaware of their surroundings.

A smaller portion of the brain is affected when dogs have partial seizures (also called focal or petite mal seizures). Dogs who are having a focal seizure are usually aware of their surroundings and their unusual movements are limited to a specific part of their body (e.g., one leg will kick out repeatedly). Seizures of any type can last for just a few seconds or continue for many minutes.

2. Aura

Before dogs have a seizure, they often act restless or behave in an abnormal way. This is called the aura, or pre-ictal stage. We don’t know exactly what dogs are experiencing during this time, but people with epilepsy describe a variety of symptoms, including seeing bright lights or spots, hearing strange sounds, smelling odd odors, or experiencing a feeling of tingling, numbness, nausea, or anxiety.

The aura typically lasts anywhere from a few seconds to several minutes but a dog’s behavioral changes may be subtle enough that it is difficult to identify this stage until you recognize what you are seeing.

3. Post-ictal Changes

The post-ictal phase occurs immediately after a seizure. Dogs often appear confused, behave in abnormal ways, and have difficulty walking.

How long the post-itcal phase lasts varies from dog to dog and from seizure to seizure in affected canines. It could last for a few hours, or for several days. During this phase, your dog is very tired, the result of the extreme brain activity manifested in the seizure. Some dogs temporarily lose vision. Normally friendly dogs might become aggressive. He still might seem disoriented, continue to salivate or move around restlessly

4. Other Signs

Many different diseases can cause seizures. Before a dog can be diagnosed with epilepsy, other conditions like low blood sugar, hypothyroidism, liver disease, kidney failure, toxic exposures, infections, trauma, and tumors or inflammation of the brain need to be ruled out.

To do this, a veterinarian will perform a thorough history and physical and neurological exam, and usually will order blood work, a urinalysis, and a fecal exam. Sometimes analysis of a sample of cerebrospinal fluid or an MRI or CT scan will also be necessary to reach a definitive diagnosis

Dogs appear to be living longer these days.  With a longer life span I am seeing many of my dog parent friends dealing with seizures in their dogs.   As in humans, there are several kinds of seizures in dogs.  Some are barely noticeable while others are significant and scary.   This will help you be aware of what to look for.
