Every puppy owner hits the same week. The needle teeth are gone, the adult teeth are pushing through, and suddenly your puppy is chewing the baseboard like it owes them money.
This is a developmental stage with a real physical driver. You can't train it away, and punishing it just makes a puppy hide the chewing. What works is management plus better options.
What's happening in your puppy's mouth
- About 3–6 weeks: 28 deciduous (baby) teeth come in, usually while the puppy is still with the litter.
- About 12–16 weeks: baby teeth start falling out. You may find tiny teeth in bedding, or never find them — most get swallowed harmlessly.
- About 4–6 months: the peak. Adult teeth erupt, gums are sore and inflamed, chewing drive spikes hard.
- About 6–7 months: all 42 adult teeth are usually in. Chewing calms down but never disappears — adult dogs still need chew outlets.
- Some blood on a toy or a little pink saliva during this window is normal.
Chewing during teething relieves pressure and discomfort. It is a need, exactly like sleep and food. Treat it that way and the whole stage gets easier.
When to call the vet
Choosing safe chews
My rule of thumb: if it doesn't give at all under your thumbnail, or you wouldn't want it dropped on your kneecap, it's too hard for a puppy's teeth.
- Good bets for teething puppies: soft rubber chew toys, rubber stuffable toys, puppy-specific chews, damp twisted washcloths frozen into a rope, silicone lick mats.
- Cold helps. Freeze a wet rolled washcloth, a rubber toy stuffed with wet food, or puppy-safe frozen broth cubes for sore gums.
- Size up. A chew small enough to fit fully in the mouth is a choking risk.
- Avoid: real bones, antlers, hooves, hard nylon, rocks, sticks, ice cubes for hard chewers — all common tooth-fracture sources.
- Avoid rawhide for puppies given the swallowing and blockage risk; safer processed chews exist.
- Supervise every new chew, and retire anything that starts coming apart in pieces.
Immediate management
Shrink the world
Playpen, gated kitchen, or a puppy-proofed room. Free run of the house during teething means constant rehearsal of chewing the wrong things.
Puppy-proof at mouth height
Cords bundled and covered, shoes away, table legs protected, remote controls up, houseplants moved. Prevention beats correction every time.
Use a tether or a crate for downtime
An overtired puppy chews harder. Enforced naps solve more teething problems than any toy.
Keep a chew in every room you use
If the right option is two feet away, redirection takes one second instead of a chase.
The redirection plan
1. Build a chew station
A mat with a chew on it in your main living space. Every time your puppy chews there, quietly praise. You're building a default location.
2. Interrupt cheerfully, never harshly
Puppy on the chair leg? A light kissy noise or your puppy's name, then move away and present a chew. No grabbing the muzzle, no yelling, no scruffing.
3. Trade, don't take
If your puppy has something they shouldn't, swap for something better rather than prying it out. Prying builds resource guarding faster than anything else.
4. Pay the right choice
When your puppy walks past a table leg and picks up a toy instead, that's the rep that matters. Mark it and praise it. Most people miss it entirely.
5. Teach a leave it and a drop it
Two cues that turn emergencies into routine. Practice them on boring objects long before you need them on a chicken bone.
6. Handle the mouth every day
Short, positive lifting of lips, touching teeth, paired with food. This makes dental checks, tooth brushing and retained-tooth exams easy for life.
7. Give the day some structure
Sleep, potty, food, short training, chew, sleep. Predictable rhythm cuts frantic chewing dramatically.
Enrichment that burns the chewing itch
- Feed at least one meal a day out of a food toy or a snuffle mat instead of a bowl.
- Frozen stuffed rubber toys: wet kibble, plain yogurt or pumpkin, frozen overnight.
- Short training games — two minutes of marker work tires a puppy more than ten minutes of fetch.
- Sniffing walks at puppy pace, letting the nose set the route.
- Cardboard destruction sessions under supervision: a box with treats inside is legal chewing.
- Rest. Puppies need 18–20 hours of sleep a day, and overtired puppies chew like sharks.
Common mistakes and troubleshooting
- Punishing chewing. It teaches secrecy and, with hands-on corrections, adds fear of people reaching toward the mouth.
- Bitter sprays as the whole plan. Some puppies genuinely enjoy them. Management plus outlets is the plan.
- Giving one toy and expecting it to compete with your entire house.
- Hard chews — antlers, bones, hooves — which are the leading cause of fractured teeth I see.
- Giving old shoes or socks as toys. Puppies cannot tell your good shoes from the retired ones.
- Free-roaming an unsupervised teething puppy and then being surprised.
- Assuming it's over at five months. Chew needs continue into adulthood, just at a lower volume.
When to bring in a professional
Reach out if the chewing looks frantic rather than contented, if it only happens when your puppy is alone, if your puppy guards items or stiffens when you approach, or if biting at hands and clothing is escalating rather than fading. Those are different problems wearing a teething costume, and they respond to a different plan.
