Reactive Seizures

Reactive Seizures 

Reactive Seizures in dogs occur when the brain reacts to a temporary disturbance elsewhere in the body, rather than due to an actual brain disorder. In simpler terms, these seizures are a response to an underlying metabolic or toxic problem, such as low blood sugar, liver dysfunction, kidney failure, or exposure to toxins. Unlike epilepsy, reactive seizures are not caused by structural brain damage, and they often stop once the primary cause is treated or removed.

Dogs experiencing reactive seizures may show sudden muscle twitching, drooling, collapse, paddling movements, or temporary loss of consciousness. After a seizure, the dog might seem confused, disoriented, or tired, and recovery may take a few minutes to several hours. Depending on the underlying cause, seizures can range from mild trembling to severe convulsions. Because the cause is external to the brain, treating the root problem is the key to preventing recurrence.

The main causes of reactive seizures include metabolic imbalances (like low blood sugar or calcium), toxin ingestion (such as chocolate, pesticides, or certain human medications), kidney or liver disease, and electrolyte disturbances. Puppies, diabetic dogs, and dogs with liver shunts are especially at risk. Since these seizures are secondary to another issue, they serve as a warning sign that the dog’s internal system is under stress or malfunctioning.

Dog Breeds Commonly Affected by Reactive Seizures

Reactive seizures can occur in any dog, but some breeds are more predisposed due to inherited metabolic or liver conditions. Breeds commonly affected include:

• Yorkshire Terriers
• Maltese
• Miniature Schnauzers
• Toy Poodles
• Dachshunds
• Border Collies
• Labrador Retrievers
• Australian Shepherds
• Samoyeds
• Beagles

Diagnosis of reactive seizures involves a comprehensive health evaluation, including blood tests, urinalysis, liver and kidney function tests, and toxin screening. Identifying and correcting the underlying cause is the most effective treatment. For instance, insulin-related seizures in diabetic dogs are managed by stabilizing blood sugar, while toxin-related seizures require detoxification and supportive care. In some cases, veterinarians may use anti-seizure medications temporarily to control the episodes while addressing the root problem.

The best way to prevent reactive seizures is through proper nutrition, regular health checkups, and keeping harmful substances out of reach. Pet owners should monitor their dogs closely for early signs of illness such as vomiting, lethargy, or appetite loss. With prompt veterinary care and a focus on treating the underlying issue, most dogs with reactive seizures can recover fully and live normal, healthy lives.
