The sleep math
8–12 week puppies need 18–20 hours of sleep daily. Most household puppies get 12–14. The deficit shows up as biting, zoomies, and tantrums.
Enforced naps
If your puppy has been awake 60 min and is biting harder, the answer is the crate, not training. Within 5 minutes most settle and sleep.
Track wake windows
Log wake → sleep cycles for 3 days. The pattern is almost always: bites = tired.
Key takeaways
- ★18–20 hours of sleep at this age
- ★Bite intensity = sleep deficit
- ★Enforced naps fix evening witching hour
