Epilepsy in Bernese Mountain Dogs

Many dogs show a warning phase in the minutes or hours before. They become clingy, restless, hide, pace or seem to be searching for their owner. Owners often recognise this only in hindsight, and noting it in a diary is genuinely useful, because it eventually allows you to prepare.

The seizure itself typically lasts under two minutes. The dog usually falls on its side, becomes rigid then paddles, may salivate heavily, and often urinates or passes faeces. It is not conscious and it is not in pain during this phase. Clear hard furniture and any stairs away from it, dim the lights, keep other pets and children out of the room, and look at a clock. If you have a second person, ask them to film.

Afterwards comes the recovery phase, which can last minutes to hours. The dog may be blind, disoriented, hungry, restless, or pace into walls. This is the stage owners find most distressing, and it is normal. Sit nearby, speak calmly, and keep the dog away from stairs and water until it is genuinely itself.

Two timings turn this into an emergency. A single seizure lasting more than five minutes, and more than one seizure within twenty-four hours without full recovery in between. Either means going to an emergency clinic immediately, because prolonged or repeated seizure activity causes body temperature to climb dangerously and can cause lasting harm. In a large, heavily coated, heat-intolerant breed, that temperature rise happens faster than in a lighter dog.

Idiopathic epilepsy, meaning epilepsy with no identifiable structural cause, typically first appears between one and five years of age. First seizures outside that window, particularly in an older dog, prompt a search for another cause, which in this breed includes the possibility of a mass given its documented cancer risk.

If you think your Bernese 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 hip dysplasia, elbow dysplasia, bloat (gdv).

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.
