Your Bernedoodle Isn’t “Naughty” — They’re Overtired (and Training Won’t Stick Until They Rest)

If your Bernedoodle turns into a tiny menace at night - biting, zooming, ignoring cues, picking fights with the lounge, acting like you’ve never met ..then welcome. You’re not doing anything wrong. You’ve just met the overtired puppy spiral.
The frustrating part? Most people respond by adding more training, more stimulation, more walking, more “burn their energy” and that’s exactly how you end up with a dog who’s more wired, not calmer.
Here’s what’s actually going on and how to fix it.
What overtired looks like in a Bernedoodle puppy
Overtired behaviour often gets labelled as:
“They’re being naughty”
“They’re stubborn”
“They have too much energy”
But overtiredness usually looks like:
frantic zoomies (that aren’t joyful… more chaotic)
bitey hands, sleeves, ankles
barking at nothing (or everything)
refusing cues they know
poor impulse control (jumping, nipping, pushing boundaries)
It’s not disobedience. It’s fatigue + overstimulation.
Why sleep matters for training (this is the science bit, but in plain English)
Dogs learn during rest. Not just “they need a break” rest ...actual sleep.
Research using EEG (brain wave monitoring) has found sleep supports memory consolidation in dogs, meaning what they practised is better retained after sleep. There’s also evidence that sleep patterns (like sleep spindles) are linked with learning performance.
So if your puppy isn’t sleeping enough, training can feel like:
progress today, chaos tomorrow
“they know it at home but not outside”
constantly repeating basics
Because their brain is running on low battery.
How much sleep do puppies actually need?
Brace yourself: puppies need a lot of sleep. Like… wildly more than most people expect.
Depending on age, puppies may sleep around 12–20 hours per day, often spread across naps and overnight sleep. Very young puppies can be at the upper end of that range.
If your puppy is awake all day and only sleeps at night, they’re probably not getting enough.
The “Witching Hour” isn’t random
That classic 6–9pm meltdown happens because:
they’ve been awake too long
the house is noisier (kids, dinner, visitors)
their nervous system is overstimulated
their body wants sleep but their brain is too aroused to settle
Overtiredness doesn’t always look sleepy. In puppies, it often looks feral.
“One of the biggest ‘aha’ moments for new puppy owners is realising the evening chaos usually isn’t attitude- it’s fatigue. When puppies are overtired, learning goes out the window. We always say: if training isn’t sticking, check the sleep before you change the plan.” - Anna Howard, Lighthouse Labradoodles and Bernedoodles
The biggest mistake: trying to “wear them out”
This is where people accidentally train the wrong thing.
If every night becomes:
puppy goes nuts
owner walks them more / plays harder
puppy gets even more wired
…you’ve created a routine where overtired behaviour gets rewarded with more stimulation.
Instead, you want to interrupt the spiral early and teach “rest is normal”.
Bernedoodle Reset Routine (simple, boring, effective) - by Lighthouse Labradoodles and Bernedoodles
Anna Howard from Lighthouse Labradoodles and Bernedoodles recommends the following routine that works for most Bernedoodle puppies because it reduces arousal without turning your evenings into a circus.
Step 1: Put naps on purpose (not “when they drop”)
Aim for a rhythm of:
60–90 minutes awake
then a nap opportunity
Use a pen or crate (where appropriate) with something calming.
Step 2: Swap late-night play for calm enrichment
Instead of wild tug and chase, try:
a stuffed Kong
snuffle mat
scatter feeding in grass
lick mat
These lower arousal rather than spike it.
Step 3: Build a predictable wind-down cue
Same order each night:
toilet
water
calm chew
lights dim
settle
Dogs love patterns. Puppies need them.
Step 4: Keep “training” short and easy at night
Night-time training should be:
2 minutes max
easy wins only
then straight into rest
If you’re asking for hard focus late in the day, you’re setting both of you up to fail.
When overtiredness might actually be something else
If your puppy is sleeping excessively and is:
hard to wake
not interested in food
unusually lethargic
vomiting/diarrhoea…that’s vet territory, not a “nap schedule” issue.
Trust your gut and get them checked.
The takeaway
If training isn’t sticking and your Bernedoodle acts possessed at night, don’t add more intensity.
Add more rest.
A tired puppy doesn’t need more entertainment. They need help switching off.
Quick FAQs
How much should my Bernedoodle puppy sleep?
Many puppies sleep 12–20 hours per day, depending on age.
Why does my puppy get bitey at night?
Overtired pups lose impulse control and self-regulation. It’s like a toddler tantrum, but with teeth.
Should I walk my puppy more to stop the zoomies?
Not automatically. If the zoomies are from overtiredness, more exercise often makes it worse. Calm enrichment + rest usually works better.
