Few things frighten a new owner more than watching their dog's head bob uncontrollably for the first time. In the great majority of cases, nothing is wrong.
The distinction that matters
The question a vet needs answered is whether the dog is conscious during the episode.
In idiopathic head tremors the dog is completely aware. It will look at you, respond to its name, take food, and walk about. The head is moving; the dog is not otherwise affected. Afterwards it is immediately normal, with none of the disorientation that follows a seizure.
A seizure is different: loss of awareness, often stiffening or paddling, frequently loss of bladder control, and a period of confusion afterwards. If any of those are present, this is not head tremors and warrants proper investigation.
Film it
The single most useful thing you can do is record an episode on your phone. A thirty-second video tells a vet more than any verbal description, and it means a decision about whether to investigate further can be made on evidence rather than recollection.
Distraction often stops it
Offering food, or engaging the dog in something interesting, frequently ends an episode. That responsiveness is itself reassuring, because it is not how a seizure behaves.
When to be concerned
Seek veterinary attention if episodes become longer or more frequent, if the dog seems unaware or disoriented, if other neurological signs appear, or if episodes start in a dog older than about four — late onset is less typical and deserves a closer look.
Signs to look for
- Rhythmic up-and-down or side-to-side head movement
- The dog remains fully conscious and responsive throughout
- No loss of bladder or bowel control
- No paddling, stiffening or collapse
- Episodes lasting seconds to a few minutes
- Normal behaviour immediately afterwards
What causes it
- Not established — idiopathic by definition
- Proposed links to low blood glucose, calcium or magnesium, none confirmed
- Sometimes triggered by stress, excitement or fatigue
How it is diagnosed
A diagnosis of exclusion. The critical distinction is from a genuine seizure: a dog having head tremors remains alert and responsive, whereas a seizing dog does not. Bloods rule out metabolic causes; imaging is reserved for atypical cases.
Treatment options
- No treatment needed in most cases
- Distraction — offering food or engaging the dog often stops an episode
- Investigation if episodes lengthen, worsen, or consciousness is affected
- Video recording of episodes, which is more useful to a vet than any description
Reducing the risk
- Not preventable
- Not known to be harmful
- Many dogs have fewer episodes as they mature
Insurance: Rarely generates a claim, but investigation to exclude epilepsy can involve bloods and occasionally MRI, which is not trivial. Once recorded, it may prompt an exclusion for neurological conditions — worth being aware of before pursuing extensive investigation of a benign phenomenon.

Common questions
Are head tremors in French Bulldogs dangerous?
In most cases no. Idiopathic head tremors are benign, the dog remains fully conscious throughout, and there is no evidence of harm. Many dogs have fewer episodes as they mature.
How do I know if it is a head tremor or a seizure?
Consciousness. A dog with head tremors stays alert, responds to you and can take food. A seizing dog loses awareness, often stiffens or paddles, may lose bladder control, and is disoriented afterwards.
What should I do during a head tremor episode?
Stay calm, film it if you can, and try offering food or a distraction — this frequently stops an episode. Note how long it lasted and what preceded it.
