Dog Milestones™ presents….
The Landshark Phase: Why Puppies BiteYour hands are scratched.
Your sleeves have holes.
You’re googling, “Is my puppy aggressive?” at midnight.
You love your puppy — but you’re starting to wonder if something is wrong.
Take a breath.
The biting.
The ankle attacks.
The sudden, sharp “landshark” moments.
Most of it is completely normal.
In Why Puppies Bite, you’ll learn what is actually happening inside your puppy’s developing body and brain — and why this stage feels so intense.
This isn’t a quick-fix training hack guide.
It’s a calm, science-based explanation of why puppies bite, what’s developmentally appropriate, and how to respond without panic.
Inside this booklet, you’ll discover:
• Why puppy biting peaks between 12–16 weeks
• The biology of teething and what it feels like for your puppy
• The difference between playful mouthing and true behavioral red flags
• How bite inhibition actually develops
• Why overtired puppies bite harder
• What is normal — and what is not
If you are:
• A first-time puppy owner
• Feeling overwhelmed and second-guessing yourself
• Bleeding daily and wondering if you made a mistake
• Afraid your puppy might be “aggressive”
This guide was written for you.
Through clear explanations, relatable real-life stories, and grounded training insight, you’ll move from fear to understanding — and from reaction to confidence.
Your puppy isn’t broken.
You didn’t fail.
You’re simply in a developmental stage that requires guidance, not panic.
When you understand the “why,” the “what to do” becomes much clearer.
Welcome to the Landshark Phase.
Let’s walk through it together.
