An overtired puppy isn’t just a bit grumpy – they’re overwhelmed, stressed, and often unable to settle without help.

Sleep is essential for puppies. It supports healthy brain development, emotional regulation, and learning. When puppies don’t get enough rest, they can quickly tip from being normally tired into overtired – and that’s when challenging behaviours start to appear.

In this guide, you’ll learn:

  • What an overtired puppy is
  • How to tell the difference between a tired puppy and an overtired puppy
  • 9 clear signs your puppy is overtired
  • Exactly how to calm an overtired puppy
  • How Zigzag helps prevent overtiredness through smarter training routines

Can a puppy be overtired?

Yes – puppies can absolutely become overtired.

Just like young children, puppies need frequent, high-quality sleep throughout the day. When they stay awake for too long, their bodies release adrenaline and stress hormones. Instead of slowing down, they become more wired – which is why overtired puppies often look hyperactive rather than sleepy.

An overtired puppy may:

  • Struggle to settle
  • Act wild or frantic
  • Bite or nip more than usual
  • Ignore cues they normally understand

You can learn more about this in our article: How often do puppies sleep?

Why you shouldn’t let your puppy get overtired

Letting a puppy become overtired doesn’t just cause short-term chaos – it can also affect their health and learning.

Overtired puppies are more likely to experience:

Even worse, overtiredness makes it harder for puppies to fall asleep, creating a cycle of overstimulation and exhaustion.

Tired vs overtired puppy (key differences)

A tired puppy and an overtired puppy can look similar at first – but their behaviour tells a very different story.

Generally, a tired puppy is calm and settles easily, while an overtired puppy is restless, noisy, and more likely to nip or act wildly.

9 signs of an overtired puppy

When puppies are overtired, self-control disappears. Adrenaline takes over, and they may seem chaotic or frantic.

Watch for these common signs:

  • Clinginess or neediness (won’t leave your side)
  • Sluggishness or lethargy
  • Ignoring cues they normally respond to
  • Excessive nipping, ankle biting, or grabbing clothes
  • Barking at people or objects
  • Panting when it’s not hot
  • Drinking water very quickly
  • ‘Crazy eyes’ (lots of white showing)
  • Chaotic zoomies, sometimes crashing into furniture

If you’re seeing several of these at once, your puppy is likely overtired – not naughty.

How to calm an overtired puppy

Helping an overtired puppy means reducing stimulation and making rest unavoidable.

Create predictable routines

Make rest easy

  • Provide a soft, cosy bed in a quiet sleep area
  • Use a heartbeat toy during your puppy’s first weeks at home

Choose calming activities

  • Sniffing games instead of high-energy play (see our 50+ training games guide for ideas)
  • Puzzle toys and food-dispensing toys (mental exercise over physical)
  • Gentle grooming or massage
  • Long-lasting chews to release calming hormones (we’ve rounded up favourites in our puppy chews article)

Model calm behaviour

  • Speak softly and move slowly
  • Reward calm moments with treats
  • Sit with your puppy until their breathing slows

FAQs

How do you settle an overtired puppy?

How do you settle an overtired puppy?
It can be hard to get your puppy to sleep right away, even if it’s all they really need.  Try to get them into it with some slow massage, talking gently to them, or give them a calming toy like a lick mat to help them wind down. 

Our article on how to calm a puppy down has a lot more helpful tips and guidance for this; have you taken a peek yet?

Is my puppy overtired or overstimulated?

It’s pretty similar, we have to admit. But the signs you’re looking for an overtired puppy are if they seem frantic, restless, overly barky or bitey. It might be the case that they’re overstimulated too – this can happen when your puppy is overwhelmed by what’s going on around them, like when you take them into a room full of children and new people. Let’s not do that when they’re this young. Bad idea. 

Do puppies act crazy when tired?

Yes, puppies often appear crazy and get the zoomies, especially when they’re  overtired. This is because they’re full of adrenaline as their body tries to keep going, even when they’re desperate to sleep. Bodies are crazy things. They need one thing, and do the other. Makes no sense, but oh well!
