Why Does My Puppy Go Crazy at Night?

Your puppy goes crazy at night because it is overtired, not because it has energy left over. This is the single most misdiagnosed puppy problem I see. Owners watch a puppy tear around the living room at eight in the evening, conclude the dog needs more exercise, add a walk, and make it worse within two days.

Puppies under six months need eighteen to twenty hours of sleep in every twenty four. Most family puppies get eleven or twelve, because there are people home, a television on, kids coming and going, and nobody enforcing rest. By evening the puppy is running on a sleep deficit, cortisol is up, and the result looks exactly like excess energy. It is the same thing that happens to a two year old human at bedtime.

How to tell the difference

Genuine under exercise looks like restlessness earlier in the day, pacing, whining, and destructive chewing spread across the whole afternoon. The overtired version has a clear time signature.

• It happens at roughly the same time every evening. Usually somewhere between seven and nine.
• It escalates fast and stops abruptly. Twenty minutes of chaos and then the puppy is asleep on the floor mid stride.
• The biting gets worse, not just the running. Land shark behavior, grabbing clothing, ignoring redirection onto toys.
• More exercise makes it worse the following night. This is the test that settles it. Add a twenty minute walk for two days and watch what happens.

The fix is a nap schedule

Enforced naps in a crate or pen. Not on the couch, not in the middle of the room, and not optional. This takes about five days to show and two weeks to fully hold.

• Ninety minutes up, then down. For a puppy under four months, the ceiling on wakeful time is about ninety minutes. Set a timer. When it goes off, the puppy goes into the crate whether it looks tired or not.
• Nap length is one to two hours. Let the puppy wake naturally. Do not open the crate the second it stirs, or you will teach a puppy to stir on purpose.
• Cover the crate. A light blanket over three sides. Visual quiet matters more than most owners think.
• Expect protest for the first three days. Ten to fifteen minutes of complaining on day one, dropping to a minute or two by day four. If it goes past twenty minutes on day one, you likely have a potty need, so take the puppy out on leash, no talking, then straight back in.
• Count naps, not hours. Four to six enforced naps across a day is the target. If you get five, the evening changes.

Reshaping the last three hours

Alongside the naps, tighten the evening itself.

• Last real meal three hours before bed. Not for digestion reasons, for arousal reasons. A meal is stimulating.
• Final nap from five to six thirty. The most important nap of the day. Skip it and the eight o'clock episode arrives on schedule.
• Trade the evening walk for a chew. Between seven and eight, give a frozen stuffed Kong or a bully stick on a mat. Chewing lowers arousal in a way that running does not. Twenty to thirty minutes of chewing is worth more than a walk here.
• Turn the house down. Lights lower, television off or quiet, kids on wind down. A puppy cannot settle in a room where three people are moving around.
• Ten minutes of place work. Puppy on a bed with defined edges while you sit nearby. Silent resets when it gets off. This is the piece that turns into a genuine off switch by six months.

What to do when it is already happening

You cannot train a puppy that is in the middle of an overtired episode. Do not try. Do not chase it, do not yell, do not wrestle. All three add fuel.

Pick the puppy up calmly, put it in the crate, cover it, and walk away. It will scream for two to five minutes and then sleep. Owners feel cruel doing this and it is the opposite of cruel. You are ending an episode the puppy cannot end on its own.

If the puppy is biting hard and you cannot safely lift it, drop a leash on it, use the leash to guide, and keep your hands off. Hands in the middle of land shark mode are a game.

The honest timeline

With a consistent nap schedule, most puppies show a noticeably calmer evening by day five and a genuinely different evening by day fourteen. If you are still getting full episodes at three weeks, something is off with the schedule rather than the plan, and the usual culprit is that naps are happening in the living room instead of the crate.

The other honest part is that some of this is age. Between four and seven months the intensity drops off on its own for most dogs, and between eight and fourteen months you will get a second, milder version during adolescence. A puppy with a nap habit rides through that far better than one without.
