Chewing, digging, jumping
Why does my puppy get mouthy and bitey in the evening?
Last updated 23 September 2026 · How we write and check this
Short answer
Many owners notice a predictable burst of energy in the early evening, sometimes called the witching hour, when accumulated tiredness paradoxically produces a final wave of hyperactivity before a puppy settles for the night. Biting tends to spike during this exact window.
The evening energy burst
A tired puppy does not always wind down smoothly, and many go through a distinct burst of zoomies and mouthiness in the hour or two before their main sleep period, likely linked to a final release of pent up energy from the day.
Timing your day around it
A short structured play session or a sniff based walk scheduled just before this predictable window can take the edge off, giving the energy somewhere to go before it turns into biting at your hands and clothes.
Riding it out calmly
When the evening burst does arrive, a chew toy, a short training session, or a calm settle routine in a pen works better than trying to physically restrain or scold a puppy through it, since that tends to add more excitement rather than less.
Key takeaways
- A predictable evening energy burst, sometimes called the witching hour, is common in puppies.
- Scheduling activity just before this window can reduce how intense the mouthing gets.
- Redirecting to a chew or calm routine works better than restraining a puppy through the burst.
