Health Basics: Canine Seizures

By Susan Tasaki, September 2015

For years, I kept a supply of phenobarbital on hand, prescribed by my vet for my mixed-breed dog's seizure. It turned out to be a one-time thing, and eventually, I disposed of the drug. But I can testify that watching her in the grip of it was both scary and confusing.

As dog-lovers, most of us hope we're never faced with a number of canine health conditions. Seizures fall into that category. When they happen, however, it's helpful to understand what we're looking at and what we need to do next.

Seizures, which are caused by abnormal electrical activity in the brain, can indicate a variety of conditions, some transitory, some longer-lasting. Our old friend "idiopathic" --or, of unknown origin--also comes into play more than either we or our vets would like. 

As explained on the Texas A&M newswire, "For some dogs, a seizure is a one-time experience, but in most cases seizures reoccur. An underlying problem in the brain could be responsible for reoccurring seizures, often resulting in a diagnosis of epilepsy. Between the many causes of seizures in dogs and the often normal lab results, idiopathic epilepsy proves to be a frequent diagnosis." Other causes include toxin ingestion, tumors, stroke, or another of several related neurological disorders.

Dr. Joseph Mankin, clinical assistant professor at the Texas A&M College of Veterinary Medicine & Biomedical Sciences, describes a typical seizure. “The dog may become agitated or disoriented, and then may collapse on its side. It may exhibit signs of paddling, vocalization, and may lose bladder control. The seizure may last for a few seconds up to a few minutes, and often the dog will be disoriented or anxious afterward. Occasionally, a dog may be blind for a short period of time.”

When a dog is in the grip of a seizure, there's little we can do, other than to keep our hands away from his or her mouth. Afterward, the most important thing we can do is take the pup to the vet for investigation into the cause. Fortunately, a number of treatments, ranging from allopathic (Western medicine) to complementary (including acupunture) exist.

Like most things, especially those related to health, knowing what we're dealing with is half the battle.
