Puppy Teething Timeline Week by Week: Symptoms & Safe Chews

Puppy Teething Timeline Week by Week: What to Expect (and How to Help)

Puppy teething can feel like a tiny, adorable shark moved into your house. The good news: it’s temporary, predictable, and very manageable when you know what’s happening in your puppy’s mouth week by week.

This guide is built around the puppy teething timeline week by week so you can match symptoms to what’s normal, know when to worry, and choose safe chews that actually work (without risking broken teeth or GI issues).

Quick Overview: Baby Teeth vs. Adult Teeth (Why Your Puppy Is So Bitey)

Puppies are born without visible teeth. They grow a full set of 28 deciduous (baby) teeth, then replace them with 42 permanent (adult) teeth. That transition creates pressure and inflammation in the gums—so chewing becomes both relief and instinct.

Here’s the big picture:

• •3–6 weeks: baby teeth erupt
• •8–12 weeks: all baby teeth are usually in
• •12–24 weeks (3–6 months): adult teeth erupt, baby teeth fall out
• •6–7 months: most puppies have a full adult set

Breed matters:

• •Small breeds (Yorkies, Chihuahuas, Maltese): more likely to retain baby teeth, often teethe “later,” and can have crowding.
• •Large breeds (Labs, Goldens, GSDs): often teethe powerfully and can demolish chews quickly—durability and safety matter.
• •Brachycephalic breeds (Frenchies, Pugs, Bulldogs): may have crowded mouths; watch for retained teeth and gum irritation.

Puppy Teething Timeline Week by Week (0–28 Weeks)

Below is a practical week-by-week guide. Remember: puppies vary by a couple of weeks in either direction.

Weeks 0–2: Toothless Newborn Stage

What’s happening: No erupted teeth yet. What you’ll notice: Nursing behavior only. What you do: Nothing teething-specific needed.

Weeks 3–4: First Baby Teeth Erupt (Incisors Start)

What’s happening: Tiny incisors begin to appear. Symptoms you might see:

• •More mouthing (gentle)
• •Mild gum sensitivity

Safe help:

• •Soft, puppy-safe rubber toys
• •Brief, supervised chew sessions

Weeks 5–6: Canines and Premolars Appear

What’s happening: Those needle-like canines come in—this is when puppies start feeling “sharp.” Symptoms:

• •Increased nipping during play
• •Gnawing on hands, sleeves, furniture edges

Real scenario: Your 6-week-old mixed breed starts grabbing pant legs every time you walk. It’s not “aggression”—it’s exploration + early oral discomfort.

Safe help: Start teaching redirecting now (details in the training section).

Weeks 7–8: Most Baby Teeth Are In (28 Total)

What’s happening: Full baby set is typically present. Symptoms:

• •Peak “landshark” behavior for many puppies
• •Mouthy play and grabbing
• •Occasional whining when chewing

What’s normal: Tiny amounts of drool, mild gum redness. What’s not: Heavy bleeding, refusal to eat, foul odor, facial swelling.

Weeks 9–10: Social Biting + Teething Overlap

What’s happening: Teeth are in, but the puppy is learning bite inhibition and may still have gum discomfort. Symptoms:

• •Biting during excitement
• •Chewing to self-soothe

Breed example: A Labrador Retriever at 10 weeks often has high oral fixation. They’ll chew because it feels good and because retrieving/mouthing is genetically rewarding.

Safe help: Rotate chews (soft-to-medium) and increase nap routine (overtired puppies bite more).

Weeks 11–12: Transition Period (Get Ready for Adult Teeth)

What’s happening: The jaw is growing; adult teeth are preparing under the gums. Symptoms:

• •Chewing intensity ramps up
• •More interest in harder textures (still keep it safe)

Tip: Take a quick mouth photo weekly. It helps you spot retained baby teeth later.

Weeks 13–14 (3–3.5 Months): Baby Incisors Start Falling Out

What’s happening: Adult incisors begin erupting; baby incisors loosen and fall. Symptoms:

• •You may find tiny teeth on the floor (or not—many are swallowed)
• •Slight blood spots on toys
• •Increased chewing + drool

What to do: Provide soothing options and reinforce chew-toys-only habits.

Weeks 15–16 (3.5–4 Months): Adult Incisors In, Canines Starting

What’s happening: Incisors look bigger and more “rectangular.” Canines begin to shift. Symptoms:

• •Gum tenderness, pawing at mouth
• •Puppy may act “cranky” in the evenings
• •Chewing baseboards/table legs increases

Real scenario: A Miniature Poodle suddenly starts chewing chair rungs at 16 weeks. Small breeds often choose narrow wood edges because they hit sore gum lines just right.

Weeks 17–18 (4–4.5 Months): Canines and Premolars Moving Fast

What’s happening: This is a big discomfort window—canines are thick and push hard through gums. Symptoms:

• •More intense chewing sessions
• •Occasional yelps if a tooth catches a toy wrong
• •More drooling and fussiness

Important: Avoid ultra-hard chews now—risk of cracked baby teeth or damaging erupting adult teeth.

Weeks 19–20 (4.5–5 Months): Premolars Erupt; Molars Start Later

What’s happening: Adult premolars come in; molars (which puppies don’t have as baby teeth) begin erupting soon after. Symptoms:

• •Chewing becomes “grindy” (back of mouth)
• •Puppy may chew with the sides of their mouth
• •Increased shredding behavior

Breed example: A German Shepherd around 5 months may start chewing like a power tool. This is where safe durability becomes crucial.

Weeks 21–24 (5–6 Months): Molars Erupt + Teething Peaks Again

What’s happening: Adult molars emerge. This can cause a second peak of discomfort. Symptoms:

• •Back-of-mouth chewing, gnawing
• •Reduced appetite for a day or two (common)
• •Slight gum bleeding possible

What you do: Increase frozen options and keep training consistent—chewing needs are high.

Weeks 25–28 (6–7 Months): Most Adult Teeth In (Finish Line)

What’s happening: Adult set is close to complete (42 teeth). Symptoms:

• •Chewing persists but becomes more “habit” than pain relief
• •Bite pressure increases (adult jaw strength)

Next phase: Transition from teething management to lifelong dental habits.

Teething Symptoms: What’s Normal vs. When to Call the Vet

Normal Teething Symptoms

Most puppies show some combination of:

• •Increased chewing (especially evenings)
• •Drooling
• •Mild gum redness
• •Loose teeth or tiny blood spots on toys
• •Mild fussiness or shorter attention span
• •Eating slightly slower for a day or two

“Call the Vet” Red Flags

Reach out if you see:

• •Heavy bleeding or bleeding that doesn’t stop
• •Facial swelling (cheek/under eye) or one-sided swelling
• •Strong foul breath (beyond normal puppy breath)
• •Refusing food/water for more than 24 hours
• •Lethargy, fever, vomiting, diarrhea (not typical teething)
• •Broken tooth (visible crack, bleeding, or the tooth looks “flat”)
• •Adult tooth erupting next to a baby tooth that won’t fall out (retained tooth)

Small-breed note: Retained baby canines are common in Yorkies/Chihuahuas. If you see “double fangs,” schedule a dental consult—retained teeth can cause crowding and periodontal problems.

Safe Chews by Age (and What to Avoid)

Choosing chews is where a lot of well-meaning owners accidentally create problems. A “tough” chew can mean broken teeth, and a “tasty” chew can mean pancreatitis or diarrhea if it’s too rich.

A Simple Safety Test for Chews

Use these quick checks:

• •Fingernail test: If you can’t dent it with your fingernail, it may be too hard for teething puppies.
• •Knee-cap rule (common vet advice): If you wouldn’t want it hit hard on your kneecap, it’s probably too hard for teeth.
• •Size rule: Chew should be larger than the puppy’s mouth to reduce choking risk.
• •Supervision: Always supervise new chew types.

Best Chew Types for Teething Puppies

These are generally the safest categories when chosen correctly:

1) Rubber Stuffable Toys (My #1 Recommendation)

Why they work: They soothe gums, occupy the brain, and can be frozen.

Good picks (widely available):

• •KONG Puppy (soft rubber designed for puppy teeth)
• •West Paw Toppl (great for meal stuffing; durable but not rock-hard)
• •KONG Goodie Bone (puppy line)

Best for: Most breeds; especially mouthy Labs, Goldens, mixes.

2) Soft-to-Medium Dental Chews (Puppy Formulas)

Look for puppy-specific versions that are softer.

Examples:

• •Vet-recommended puppy dental chews (varies by region/brand)
• •VOHC-approved options when age-appropriate (ask your vet; VOHC list is a solid standard)

Best for: Puppies who need a “legal chew” during witching hour.

3) Edible, Digestible Chews (Use Carefully)

Examples:

• •Bully sticks (odor-free versions exist; choose thickness appropriate to size)
• •Collagen sticks (often more digestible than rawhide)
• •Single-ingredient tendon chews (watch richness)

Safety tips:

• •Use a bully stick holder to prevent swallowing the last chunk.
• •Limit to avoid GI upset—start with 5–10 minutes.

Best for: Moderate chewers; not ideal for puppies with sensitive stomachs.

4) Frozen Washcloth “Gum Soother” (Cheap and Effective)

This is surprisingly helpful during canine/molars weeks.

How to do it:

1. Wet a clean washcloth.
2. Twist it into a rope shape.
3. Freeze it for 1–2 hours.
4. Offer under supervision for 5–10 minutes.
5. Take away when it starts shredding.

Best for: All breeds, especially during 4–6 months.

Pro-tip: If your puppy loses interest fast, rub a tiny smear of canned puppy food on the cloth before freezing.

Chews to Avoid (Common Mistakes)

These cause the most problems in real life:

• •Cooked bones (splinter risk + tooth fractures)
• •Antlers (too hard; fracture risk)
• •Hooves (too hard; can splinter)
• •Hard nylon/plastic “indestructible” chews (often too hard for teething mouths)
• •Rawhide (choking/blockage risk; varies widely in digestibility and processing)
• •Tennis balls as chew toys (the fuzz can wear enamel; fine for fetch, not chewing)
• •Ice cubes for heavy chewers (can crack teeth; small crushed ice is safer than big cubes)

Step-by-Step: How to Manage Teething Biting (Without Harsh Corrections)

Teething discomfort and normal puppy play biting overlap—so you need a plan that teaches manners and provides relief.

Step 1: Set Up a “Chew Menu”

Have 3–5 options ready at all times:

• •1 frozen option (Toppl/KONG or washcloth)
• •1 rubber chew
• •1 edible chew (short sessions)
• •1 comfort toy (soft plush for carrying, not intense chewing)

Rotate daily to keep novelty high.

Step 2: Use the “Bite → Freeze → Redirect” Pattern

When teeth hit skin:

1. Freeze your hand/body (no jerking—movement makes it fun).
2. Calmly say a cue like “Too bad” or “Oops”.
3. Immediately offer a legal chew toy.
4. The moment they bite the toy, praise (“Good chew!”).

Consistency matters more than intensity. You’re teaching a clear rule: teeth belong on toys.

Step 3: Add a Short Timeout (Only If Needed)

If your puppy is over-aroused and keeps biting:

1. Calmly place them in a puppy-safe pen/crate with a chew.
2. 30–60 seconds is enough.
3. Bring them back out and try again.

Timeouts aren’t punishment—they’re a reset.

Pro-tip: If biting spikes at the same time every night, it’s often overtiredness. Add a nap 30 minutes earlier.

Step 4: Protect the Environment (So They Don’t Practice Bad Chewing)

Common teething targets and fixes:

• •Table legs/baseboards: use baby gates, exercise pen, and bitter deterrent (test first)
• •Shoes/socks: store in closed bins; puppies love salty smells
• •Rugs: provide a tug toy and increase mental enrichment

Breed-Specific Teething Challenges (Examples That Match Real Homes)

Labrador Retriever (and Other Retrievers)

Typical challenge: constant mouthing + strong jaws early. What helps:

• •Stuffed/frozen rubber toys daily
• •Short training games that reward calm mouth (sit → treat, hand target)
• •Durable but not rock-hard chews

German Shepherd / Belgian Malinois

Typical challenge: intense drive + destructive chewing during peak teething. What helps:

• •Structured chew time after exercise
• •A strict rotation of safe chews
• •More supervision; they can swallow chunks quickly

French Bulldog / Pug

Typical challenge: crowded teeth, sensitive gums, sometimes slower tooth loss. What helps:

• •Softer chews, smaller sizes
• •Vet check if teeth look crowded or breath becomes strong
• •Early dental hygiene habits (gentle brushing)

Yorkshire Terrier / Chihuahua

Typical challenge: retained baby teeth (especially canines). What helps:

• •Weekly mouth checks
• •Early vet dental consult if “double teeth” appear
• •Avoid very large/hard chews; choose tiny, appropriate options

Product Recommendations (Practical Picks + Comparisons)

You don’t need 20 products—just the right categories.

Best “All-Around” Teething Setup

• •KONG Puppy (stuff/freeze; great gum relief)
• •West Paw Toppl (easy to fill; often more stable than classic KONG shapes)
• •Bully stick + bully holder (short, supervised sessions)
• •Soft puppy dental chew (for structured chew time)
• •Crate/pen (for enforced naps and preventing destructive chewing)

KONG Puppy vs. Toppl (Quick Comparison)

• •KONG Puppy: classic, bouncy, can be harder to clean depending on size; great for freezing.
• •Toppl: wide opening, easier stuffing/cleaning; often better for meals.

If your puppy gives up quickly because it’s hard to access the filling, try Toppl.

Bully Sticks vs. Collagen Sticks

• •Bully sticks: very motivating; can be rich; choking risk at the end without a holder.
• •Collagen sticks: often less greasy, can last longer; still needs supervision.

For sensitive stomachs, start with a shorter session and watch stool for 24 hours.

Feeding and Comfort Hacks During Peak Teething (3–6 Months)

If Your Puppy Eats Slower or Seems Sore

Try:

• •Soften kibble with warm water for 5–10 minutes
• •Use a lick mat with a thin spread of wet puppy food (supervised)
• •Feed part of meals in a stuffed toy (less gulping, more soothing)

DIY Stuffing Ideas (Puppy-Safe)

Use small amounts at first:

• •Wet puppy food
• •Plain canned pumpkin (small amounts)
• •Plain yogurt (if tolerated)
• •Soaked kibble mashed into paste

Avoid xylitol-containing peanut butter and overly fatty mixes.

Pro-tip: Freeze stuffed toys in layers (stuff → freeze 20 min → add more → freeze). It lasts longer and reduces frustration.

Common Teething Mistakes (That Make Things Worse)

• •Buying the hardest chew possible “so it lasts.” This is a top cause of tooth fractures.
• •Letting puppies free-roam during peak teething. They will practice chewing furniture—then it becomes a habit.
• •Punishing biting (yelling, tapping the nose). It increases arousal and can create fear around hands.
• •No nap schedule. Overtired puppies bite more and chew destructively.
• •Too many rich chews at once. Diarrhea is often a “new chew overload,” not teething itself.
• •Skipping mouth checks. Retained teeth are easier (and cheaper) to address early.

Mouth Checks and Dental Care: Start Now (It Pays Off for Life)

Weekly 30-Second Mouth Check

Pick a calm moment:

1. Lift lips gently.
2. Look for double teeth, especially canines.
3. Check gums for swelling, redness, or ulcers.
4. Smell breath (sudden foul odor can signal infection).

When to Brush Teeth

You can start training the routine early:

• •Use dog toothpaste only
• •Start with finger brushing or a soft puppy brush
• •10–20 seconds at first, then build

Even if you only brush a few times a week, you’re building a habit that prevents dental disease later.

Teething FAQ (Fast, Useful Answers)

Do puppies get a fever when teething?

True fever isn’t typical. If your puppy seems hot, lethargic, or unwell, don’t assume it’s teething—call your vet.

Is it normal for puppies to swallow baby teeth?

Yes. It’s common not to find them. Small teeth often get swallowed during play or eating.

When should I worry about retained baby teeth?

If an adult tooth is clearly erupting and the baby tooth is still firmly in place for more than a couple weeks—especially canines—book a vet visit. Small breeds are high risk.

How long does teething last?

Most puppies finish around 6–7 months, but chewing habits can continue. The goal is teaching what to chew.

A Simple “Teething Day Plan” (So You’re Not Guessing)

If you want a routine that works for most households:

1. Morning: short walk/play → 10 minutes stuffed toy
2. Midday: training session (5 minutes) → nap in crate/pen
3. Afternoon: supervised chew (rubber toy) → calm play
4. Evening witching hour: frozen Toppl/KONG + short timeout if bitey
5. Before bed: potty + calm settle with a soft toy

This reduces biting by meeting the need (chew relief) before your puppy invents their own solutions (your couch).

Final Takeaway: Match the Chew to the Week

The best way to survive teething is to treat it like a predictable developmental stage:

• •Expect chewing spikes around 14–24 weeks
• •Use soft-to-medium safe chews—especially frozen stuffables
• •Supervise, rotate options, and prevent access to furniture
• •Watch for red flags like swelling, broken teeth, or persistent retained baby teeth

If you tell me your puppy’s age (in weeks), breed, and chew style (gentle vs. power chewer), I can suggest a tight “chew rotation” that fits your household and budget.
