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
