Published by The Complete Dog Guide
If your once-sweet puppy has suddenly started chewing everything in sight — shoes, furniture, hands — you’re likely experiencing one of the most common developmental stages: teething.
Puppy teething is a normal biological process that occurs during early growth. Understanding when it happens, why chewing increases, and how to manage it properly can prevent frustration and protect your home.
This guide breaks down the complete puppy teething timeline — from baby teeth to adult teeth — and explains how to support healthy development.
Puppy Development Stages: The Ultimate Week-by-Week Guide
🍼 Stage 1: Baby Teeth Erupt (2–4 Weeks)
Puppies are born without visible teeth.
Around 2–3 weeks of age, the first baby teeth (also called deciduous teeth) begin emerging.
By 6–8 weeks, most puppies have a full set of 28 baby teeth.
At this stage:
• Puppies are still with their litter
• Chewing begins lightly
• Bite inhibition learning develops through play
Early chewing is part of normal exploration.
🧠 Stage 2: Pre-Teething Behavior (8–12 Weeks)
Most puppies go home around 8 weeks of age — just before major teething begins.
During this phase, owners may notice:
• Increased mouthing
• Exploration with teeth
• Light chewing behavior
• Play biting
This stage overlaps with the primary socialization window and the first fear period.
Puppy Socialization Periods Explained
It’s important not to confuse developmental mouthing with aggression.
🦷 Stage 3: Active Teething Phase (3–6 Months)
This is when teething intensifies.
Between 3 and 6 months:
• Baby teeth begin falling out
• Adult teeth start erupting
• Gums become sore
• Chewing behavior increases dramatically
You may find small teeth on the floor — this is normal.
Common Teething Symptoms
• Increased chewing
• Mild gum bleeding
• Drooling
• Irritability
• Preference for cold objects
Teething can be uncomfortable, but it is temporary.
🧊 How to Help a Teething Puppy
Providing safe outlets for chewing is essential.
✔ Offer Appropriate Chew Toys
Choose:
• Durable rubber toys
• Textured chew items
• Puppy-safe teething toys
Avoid hard bones or objects that could damage developing teeth.
✔ Use Cold Relief
Cold can soothe sore gums.
• Refrigerated chew toys
• Cold washcloths (supervised)
• Puppy-safe frozen treats
Never use ice cubes unsupervised.
✔ Redirect, Don’t Punish
If your puppy chews furniture or hands:
• Redirect to an appropriate toy
• Praise when chewing the correct item
• Stay consistent
Punishment can create confusion during this developmental stage.
⚠️ When Does Teething Peak?
Teething behavior is typically strongest between 4 and 5 months.
This overlaps with the juvenile stage, when energy levels also increase.
This combination often makes puppies seem “out of control,” but it’s normal growth.
🐾 Stage 4: Adult Teeth Complete (6–7 Months)
By 6–7 months:
• Most adult teeth are in place
• Chewing intensity decreases
• Gum discomfort subsides
Puppies now have 42 adult teeth.
Chewing does not disappear completely — but it shifts from discomfort-driven to behavior-driven.
🧠 Teething vs Behavioral Chewing
It’s important to distinguish between:
Teething Chewing
• Driven by gum discomfort
• Peaks between 3–6 months
• Gradually declines
Behavioral Chewing
• Caused by boredom
• Linked to lack of exercise
• May continue into adolescence
If destructive chewing continues beyond 7–8 months, structure and enrichment may need adjustment.
🧬 Why Puppies Chew More During Development
Chewing serves multiple developmental purposes:
• Relieves gum pressure
• Strengthens jaw muscles
• Encourages exploration
• Reduces stress
• Provides sensory stimulation
Chewing is biologically normal — but boundaries are necessary.
🚫 Common Teething Mistakes
Many owners accidentally reinforce bad habits.
Avoid:
• Allowing hand biting during play
• Inconsistent rules about furniture
• Giving inappropriate chew objects
• Ignoring exercise needs
• Overreacting to normal mouthing
Consistency prevents confusion.
🏋️ Exercise & Mental Stimulation During Teething
Physical exercise alone is not enough.
Include:
• Short training sessions
• Food puzzle toys
• Basic obedience practice
• Structured play
Mental stimulation reduces destructive behavior.
🐕 Does Breed Affect Teething Intensity?
All puppies teethe — but chewing intensity can vary based on:
• Energy level
• Jaw strength
• Temperament
• Working drive
High-drive breeds may require more redirection and structure.
❓ Frequently Asked Questions
When do puppies start teething?
Around 3 months old.
When does puppy teething stop?
Typically by 6–7 months.
Is it normal for gums to bleed?
Mild spotting can occur as baby teeth fall out.
Should I worry if I don’t find baby teeth?
No. Puppies often swallow them.
Why is my puppy biting more at 4 months?
This is peak teething age.
🧭 Final Thoughts
Puppy teething is temporary — but it requires preparation and patience.
With:
• Safe chew options
• Consistent redirection
• Structured training
• Adequate mental stimulation
Most puppies transition smoothly through this stage.
