Health & Medical

My father rang me at seven in the morning to say the dog had had a stroke. Twelve years old, head cocked hard to one side, staggering in circles, eyes flicking back and forth like something was scrolling past them, and he had been sick on the hall carpet.

It was not a stroke. It almost never is.

What it was is called idiopathic vestibular disease, and it is the single most alarming-looking condition in old dogs that usually gets substantially better on its own. The vestibular system is the balance apparatus in the inner ear and the part of the brain that reads it. When it misfires, the dog's world is spinning at speed and he cannot stand up in it, and the way that presents looks exactly like a catastrophic brain event to anyone watching.

The signs cluster together and they are distinctive once you have seen them. A head tilt, often quite extreme. Circling or falling towards the tilted side. Nystagmus, which is the eyes drifting or jerking rhythmically. Vomiting and drooling, because he is profoundly travel-sick without moving. Refusing to walk, or walking like a drunk. Some dogs cannot stand at all for the first day.

Idiopathic means nobody knows why. It arrives suddenly in dogs usually over eight, with no warning, no injury, no illness beforehand. Old dog vestibular syndrome is what most vets call it.

Getting seen anyway, because the mimics matter

None of the above means stay home. Several serious things produce the same picture and only a vet can sort them out, so this is a same-day appointment.

The commonest alternative explanation is a middle or inner ear infection, which is treatable and which will keep getting worse if missed. That is why the vet looks down both ears carefully. Others include a brainstem problem, a tumour, low thyroid, and certain drug toxicities, notably some older antibiotics that damage the inner ear. Genuine strokes do happen in dogs but they are rare compared to how often owners assume one.

The clue vets use most is where the eyes go and which direction the dog falls, along with whether anything else neurological is off. A peripheral problem, meaning the ear itself, tends to spare the rest of the nervous system. A central problem, meaning brain, usually comes with other deficits, and that changes the outlook completely. Sometimes the honest answer is a period of watching, and sometimes it is an MRI at a referral practice if things do not improve.

The good news is the trajectory. In the idiopathic form the worst is the first twenty-four to forty-eight hours. Most dogs are noticeably steadier by day three, walking by the end of the first week, and largely normal within two to three weeks. A residual head tilt frequently stays forever, which looks slightly comic and bothers the dog not at all. Some dogs get a recurrence months or years later.

The nursing is the whole job in those first days, and it is real work.

Keep him on the floor in a small padded space, away from stairs, and put something at the edges so he cannot roll into furniture. My father used sofa cushions round three sides of a dog bed. Do not leave him where he can fall down a step, because he genuinely cannot judge one.

Hold the water bowl to him rather than expecting him to find it. Dehydration is the thing that turns a self-limiting condition into a hospital admission, and a dog who is nauseous and cannot walk will simply not drink. Hand-feeding something strong-smelling works, and if he will not eat or drink for a day, the vet can give fluids.

The vet can also give anti-nausea medication and it makes an enormous difference. Maropitant or similar stops the vomiting and lets him rest, and a sedative for the first night is sometimes kind. There is no drug that fixes the underlying problem, whatever anyone sells you, and the various supplements marketed for it have no evidence behind them.

Support him with a towel under the belly for toilet trips, one person holding, one guiding. Big dogs need two people. Expect accidents and put a puppy pad down without making a thing of it, because a dog who is embarrassed and cannot get outside will hold it and make himself ill.

Do not stop him moving once he is trying. The brain compensates by using vision and touch to recalibrate, and that only happens with practice. Short supported walks on grass, several times a day, are exactly right by day three or four. My father was carrying his dog everywhere out of kindness and the vet told him to put him down and let him wobble.

He recovered. Kept a slight tilt to the left for the last three years of his life, which meant every photograph of him looked like a question.
