Every evening, at roughly the same time, a switch flips. Your reasonable puppy starts sprinting in circles, grabbing trouser legs, biting harder than usual and ignoring every word you say. New owners call it the witching hour. It is one of the most common questions in the first month, and one of the most misunderstood.
What zoomies actually are
The proper name is a frenetic random activity period. A sudden burst of running, spinning and play-biting that lasts a minute or two and ends as abruptly as it started. It is normal, it is healthy, and in a loose, wiggly body it is a sign of a happy puppy - often after a nap, after a bath, or after a poo.
The evening version is different. That one is not joy. That one is exhaustion.
The real cause is almost always sleep
Puppies need 18 to 20 hours of sleep a day and can only stay awake for about 45 to 90 minutes at a stretch. By late afternoon most puppies have been under-napped all day, usually because the household has been busy and awake. An overtired puppy behaves exactly like an overtired toddler: wired, frantic, unable to settle, and much bitier than usual.
Which is why the standard advice - more exercise - usually makes it worse. Another walk at 5pm adds stimulation to a brain that already cannot cope.
The five-step evening routine
- Nap earlier. Enforce a real nap in the crate or pen around mid-afternoon, door shut, you out of sight. This one change fixes the majority of witching hours.
- Feed, then wind down. Keep the final hour quiet. No wrestling, no visitors, no new toys, no chasing games.
- Swap exercise for sniffing. Scatter their evening meal on a towel, or give a lick mat or a stuffed frozen toy. Licking and sniffing are self-soothing; running is not.
- Have an exit ready. When the biting starts, do not negotiate. Calmly move them into the pen or crate with a chew. You are not punishing them, you are putting an overtired child to bed.
- Same time every night. Last potty, lights out, same order. Predictability is what switches a puppy off.
If the zoomies happen anyway
Do not chase, and do not grab. Chasing turns it into the best game of the day and can teach a lasting habit of running away from you. Instead: clear the space of anything breakable, sit down, be boring, and let it burn out - it is usually over in under two minutes. If it is happening on a slippery floor, put a rug down; that is where most zoomie injuries happen.
When it is not just zoomies
Speak to your vet or a qualified force-free trainer if the biting is stiff rather than wiggly, comes with growling and a hard stare, breaks skin repeatedly, or if the episodes get longer and more intense over weeks rather than shorter. Also worth a vet conversation: frantic scratching or spinning that looks compulsive rather than playful, or a puppy who never seems able to settle at any time of day.
The evening routine, the nap schedule and a page for every one of these moments are in The First-Year Puppy System. If it is the nights that are breaking you right now, start with the free 2am page. And on the days you cannot get outside, the indoor games list is a better plan than another walk.
