Module 1: Why Puppies Bite
Understanding the developmental driver makes the behavior much easier to manage.

Three causes
Teething (physical discomfort), exploration (mouth = hands), and bite inhibition learning (calibrating jaw pressure with littermates and you).
Peak window
10–20 weeks is the worst. By 5–6 months baby teeth fall out and biting drops dramatically. By 7 months it should be a memory.
Not aggression
Land-shark mouthing is normal puppy behavior, not a personality flaw or predictor of an aggressive adult.
Key takeaways
- ★Biting is developmental, not character
- ★Worst 10–20 weeks
- ★Done by ~7 months
