Dr. Voss Explains Pet Seizure Diagnosis and Emergency Protocols

Aspen —Your dog just collapsed, shook violently for forty seconds, and now looks confused. Is that a seizure?

The short version: yes, it probably is. But not always.

Dr. Voss writes in the Aspen Times that a seizure is an episode of abnormal, excessive electrical activity in the brain. It’s not just full-body convulsions. Some seizures are subtle. Facial twitching. Repetitive movements. Unusual behavior. Voss notes that focal seizures affect only part of the body, while generalized ones look like full-body convulsions. They are unpredictable. That makes them hard for pets and their guardians alike.

When a pet has its first seizure, the vet’s job is to find the cause. Voss divides those causes into two buckets: extracranial and intracranial.

Extracranial means the problem is outside the brain. Low blood sugar. Toxin exposure. Liver or kidney disease. Electrolyte imbalances. These conditions disrupt brain function even if the brain itself is healthy. Intracranial means the problem is inside the brain. Epilepsy. Tumors. Infections. Inflammatory diseases.

The initial diagnostic approach focuses on ruling out extracranial causes first. Why? Because they are often easier to investigate and frequently treatable. Voss says a thorough medical history, physical exam, and neurological assessment are the first steps. Routine bloodwork — a complete blood count and biochemistry panel — can identify metabolic abnormalities or organ dysfunction.

Here is the part most people miss: record it on your phone.

Voss writes that not every event that looks like a seizure actually is one. Fainting episodes, vestibular disturbances, and painful muscle tremors can look similar but require different treatments. Details matter. How long did the episode last? What was your pet doing beforehand? How quickly did they recover? Those details help narrow down the possibilities.

If your pet is actively seizing, keep them away from stairs and furniture edges. Do not restrain them. Keep your hands out of their mouth. Time the episode.

Make no mistake: a seizure lasting longer than five minutes is a medical emergency. Two or more seizures within 24 hours? Also an emergency. Bring the pet to the hospital immediately. Do not wait for it to “pass.”

Once extracranial causes are investigated, further testing may be needed to evaluate intracranial issues. The article cuts off there, but the implication is clear: if bloodwork comes back normal, you’re looking at something inside the skull. That usually means advanced imaging or more specialized neurological testing.

What Voss isn’t saying is what it costs to get to the bottom of this. Bloodwork, neurological exams, MRI scans, these are not cheap. For folks in the valley, that means a trip to a specialist, likely in Denver or Boulder, unless local clinics offer the full workup. The article doesn’t mention pricing, travel time, or insurance coverage. It assumes you have the resources to follow through on every test recommended.

The scary part isn’t just the seizure. It’s the uncertainty after. You watch your dog for weeks, waiting for the next one. You check their eyes every time they blink. You learn to read the difference between a shiver and a focal seizure. It changes how you live with your pet.

Voss emphasizes that seizures are notoriously unpredictable. There is no schedule to anticipate them. You just have to be ready.

If you’re in Aspen or nearby and your pet has had a first-time event, the immediate step is clear: call your vet. Get bloodwork done. Record the next episode if it happens. And know that five minutes is your cutoff for rushing to the ER.

The article ends mid-sentence, just as it starts discussing further testing for intracranial causes. That’s where the real work begins - and where the questions get harder to answer.
