Puppy raising
Overtired puppy zoomies and biting
It is 7 pm and the sweet puppy from this morning has been replaced by a tiny crocodile doing laps. Hands, ankles and the corner of the rug are all fair game. Owners often read this as the puppy testing them. We read it as a question: how much rest has this puppy actually had today, and what else is going on? Fatigue is one common answer, and we would rather check than assume.

What to observe
Count the awake hours before you name the cause.
Puppies often spend a large part of each day asleep, and in our experience evening is when awake time stacks up: the family is home, dinner is happening, and everyone wants the puppy. So before naming the cause, we suggest looking back over the day. When did the puppy last sleep properly, and for how long? Has anything changed lately: food, routine, visitors, teething? A long, busy awake stretch makes fatigue a reasonable suspect. It does not make it the only one.
The wind-up often has a look to it: rougher play, sleeves grabbed instead of toys, a chew that cannot hold attention, barking at nothing in particular. We treat that as a cue to lower the energy in the room. Stop the game and offer a familiar, quiet place to rest, a crate or pen the puppy already knows, somewhere you can still see it. If it cries hard or gets more frantic instead of settling, we would not leave it alone to protest.

Rhythm and red flags
Short awake stretches, safe chews, and when to look closer.
Prevention is mostly a rhythm: a short burst of play, a potty trip, then rest in a familiar spot, repeated through the day so awake stretches stay short and rest is not left to chance. Chews help many puppies settle, and we suggest choosing ones sized for the puppy and staying in the room while it works on one. Mid-wind-up, every move is a calm one: a lower voice, no chasing, no wrestling, and tug or roughhousing put away for the evening.
Some biting deserves a closer look than a nap schedule: biting that runs all day rather than at dusk, with a stiff body and a hard stare, or over the food bowl or a resting spot. We would want to see that puppy first, and any sudden change is a vet question before it is a training one. If the daily rhythm is the hard part, Puppy Fundamentals includes a structured routine and crate comfort, nights included, with a handover lesson at the end.
Asked and answered
The questions people ask us.
Why does my puppy go crazy in the evening?
Often because it has been awake and stimulated for longer than it can manage, though that is one explanation rather than the only one. We suggest counting back to the last real nap and noting what the afternoon looked like before deciding. If the pattern holds across several evenings, shorter awake stretches through the day are the first thing we would change.
What is the puppy witching hour?
It is the nickname for an evening stretch when a puppy sprints laps, bites hard and ignores everyone. In many puppies it lines up with a long, busy awake period, but it is a description of what you see, not a diagnosis. We treat it as a prompt to look at the day's rest and routine.
How do I calm an overtired puppy?
We suggest doing less, not more: stop the game, lower your voice, take the puppy out to potty, and offer a familiar, quiet place to rest where you can still see it. A supervised chew sized for the puppy helps some settle. If the puppy cries hard or gets more frantic rather than settling, we would not leave it alone, because that is a puppy that needs something else looked at.
Is overtired puppy biting normal?
Harder, faster biting at the end of a long awake stretch is common in young puppies. Whether it eases after rest is something we would observe rather than assume. Biting that happens all day, with a stiff body, or over food and resting spots is different and deserves a professional look, and any sudden change is a question for your vet first.
