Why do dogs get the zoomies?
The behaviour has a proper name — Frenetic Random Activity Periods (FRAPs) — and it is a normal, healthy release of built-up energy or arousal.
What it looks like: a sudden burst of running in tight circles or figures of eight, often with a distinctive tucked rear end, wide eyes, a play bow, and an expression of manic joy. It typically lasts a few minutes and ends abruptly.
When it happens, and the timing is informative:
After a bath. Extremely common. Likely a combination of relief that a disliked experience has ended, discomfort at being wet, and the urge to dry off by friction against carpet and furniture.
In the evening, particularly in puppies. Energy accumulated through a low-activity day discharges at once.
After a period of confinement — a crate, a car journey, a vet visit.
After toileting, which is common and not fully explained.
During or after play, as excitement peaks.
In young dogs far more than old ones. Puppies FRAP constantly; it declines with age, though many dogs do it throughout life.
Why it happens. The best explanation is arousal regulation — a discharge of accumulated physical or emotional energy that the dog has no other outlet for. It can follow excitement, relief, or the release of tension after something stressful, which is why it appears in seemingly contradictory situations.
Cats do it too, often at night, and it is generally attributed to the same accumulated-energy mechanism plus their crepuscular activity pattern.
Is it a problem? Almost never. It is a sign of a happy, healthy animal.
When to pay attention: if it happens constantly and the dog seems unable to settle at all, that may indicate insufficient exercise or mental stimulation rather than a behavioural problem. And ensure the environment is safe — hard floors cause slips and injuries, so clearing space and providing grip matters more than trying to stop it.
Do not chase, which extends it.
