Seizures and Epilepsy in Papillons: The First Five Minutes and the Longer Question

Note the time. Everything about the decision that follows depends on duration, and a seizure that feels like ten minutes is usually ninety seconds.

Do not put your hands near the mouth. A seizing dog has no control over its jaw and cannot swallow its tongue, so there is nothing to protect and a real risk of a serious bite. Move furniture away rather than moving the dog, unless it is near stairs or water.

Dim the lights, turn off the television, and keep your voice quiet. Sensory input can prolong an episode.

Film it if you can hold a phone steady. What a neurologist wants to see is whether the whole body is involved or one side, whether the head turns consistently one way, and how the dog behaves in the minutes afterwards.

Afterwards expect a recovery period: disorientation, pacing, temporary blindness, ravenous hunger or thirst. This can last minutes to hours and is normal. Offer water once the dog can stand and swallow properly, and keep the environment quiet.

Low blood sugar is first on the list, particularly in puppies and very small adults. A Papillon at the light end of the five to ten pound range carries a limited glycogen reserve, and a missed meal, a bout of vomiting, or hours of intense play can drop glucose enough to cause weakness, wobbling and then convulsions. It is found on a blood test taken close to the event and is treated directly.

A portosystemic shunt is next. When blood bypasses the liver, toxins reach the brain, and the signs are neurological: disorientation, circling, head pressing and seizures, classically an hour or two after a meal. It is more common in toy breeds than in large ones and is screened for with a bile acid test.

Hydrocephalus, an accumulation of fluid within the brain, is worth mentioning because an open fontanel is documented in Papillons. A persistent skull gap alone is common and usually harmless, but a large one in a dog with a domed head and neurological signs raises the question.

Toxins, head trauma and, in older dogs, a brain tumour complete the main list.

If you think your Papillon has epilepsy, the plan is three steps: write down what you have seen and when it started, book a veterinary appointment rather than waiting for the next flare, and take video of the behaviour or symptom before you go — the thing you are worried about rarely happens in the consulting room. Screening in the parents covers patellar luxation, progressive retinal atrophy, dental disease.

What the vet visit should produce is a diagnosis and a written plan, not just reassurance: what is being ruled out, what the monitoring interval is, and which signs mean you come back sooner. Ask what the treatment costs across a year rather than per visit, because that is the number that decides whether you are managing this condition or reacting to it.

Between appointments, keep a short log — dates, what you saw, what changed. It is the single most useful thing an owner brings to a follow-up, and for epilepsy it is often what separates a clear pattern from a guess.
