Puppy Teething: Why Cold Helps and What Is Safe at 12 Weeks
Around 16 weeks, your puppy will start chewing everything within reach, and it will feel like a behaviour problem. It is not. Their gums are inflamed, adult teeth are pushing through, and chewing is the only relief available to them.
You cannot stop it. You can give it somewhere acceptable to go, and cold is the most effective tool you have.
The timeline
Knowing where you are in the process tells you what to expect and when it ends.
| Age | What is happening |
|---|---|
| 3 to 6 weeks | Baby teeth erupt, while still with the litter |
| 8 weeks | All 28 baby teeth present. Usually collection age |
| 12 to 16 weeks | Incisors start falling out. You may find rice-sized teeth |
| 16 to 24 weeks | Canines and premolars erupt. The worst phase |
| 6 to 7 months | All 42 adult teeth in place. Teething over |
PetMD confirms the broad shape: baby teeth begin erupting around three weeks, and most puppies finish teething by about six months.
The phase that matters most is 16 to 24 weeks. As one veterinary timeline describes it, this is often the most intense chewing phase, when gums are inflamed and the urge to bite is strongest, as the canine teeth and premolars erupt.
Plan for it. If your puppy came home at eight weeks, you have roughly two months before the difficult stretch. Use them to build habits and stock the freezer.
Why cold works
This is not folklore. Cold reduces inflammation and numbs tissue, which is the same reason you would put ice on a sprain.
The Elita veterinary timeline puts it directly: During peak teething, the gums are inflamed and sensitive, and cold objects help by reducing inflammation and numbing the tissue. Frozen damp washcloths, chilled carrots, or purpose-designed rubber chew toys are effective and safe.
Two things follow.
A frozen fill does two jobs at once. It numbs the gums and it occupies the puppy for 20 to 30 minutes. Nothing else in your toolkit does both.
Frozen is not the same as rock hard. There is a real difference between a soft-frozen fill inside a flexible rubber toy and a solid block of ice. Very hard objects can damage developing teeth. Cold and yielding is what you want.
What is safe at each stage
Adjust the fill to where the puppy actually is.
8 to 12 weeks: soft and small
Teeth are all baby teeth and the puppy is still settling into your home. Keep it plain.
- Soaked kibble from their own ration, packed loose.
- A teaspoon of plain full-fat yoghurt.
- 100% pumpkin purée.
- Mashed banana.
Freeze for two or three hours rather than overnight, so the texture stays yielding. Portions are tiny at this age, and taking the fill out of their measured daily food avoids adding anything.
A small FreezBone holds up to 45g of filling, which is more than an eight-week-old needs in one session. Fill it partially. The small dog range covers the right scale.
12 to 16 weeks: introduce texture
Incisors are being replaced. The puppy can handle a firmer fill.
- Soaked kibble packed tighter.
- Layered fills: pumpkin at the back, yoghurt in the middle.
- Freeze overnight now.
- A few frozen blueberries or green beans suspended in the fill.
16 to 24 weeks: the peak
This is when you need volume, duration and several toys.
- Freeze everything solid, overnight.
- Layer properly so it lasts.
- Two or three sessions a day during the worst of it.
- Rotate shapes so the puppy does not solve one and lose interest.
Different cavity shapes release food differently, which matters when a puppy is chewing several times a day. The FreezBall and the stackable FreezBrick give you two quite different jobs to solve, and the frozen toys range covers the rest.
Combinations that hold together are in our recipe collection.
6 months onwards
Teething is finishing but chewing is not. Adolescent chewing runs on separately, driven by boredom and development rather than sore gums, and it often gets worse just as the teeth settle. Keep the routine going.
Safe and unsafe cold options
Safe:
- Purpose-made rubber toys with a frozen fill.
- Frozen damp washcloth, supervised, discarded once it starts to shred.
- Chilled carrot sticks, whole and supervised.
- Frozen green beans.
- Their own soaked kibble, frozen.
- Plain frozen pumpkin or banana.
Not safe:
- Ice cubes as a chew. Too hard for developing teeth, and a choking risk in the wrong size.
- Frozen bones. Splinter risk, and much too hard.
- Anything sugar-free. Xylitol is dangerous in small amounts, and it appears in yoghurts, peanut butters and sugar-free honey. Our xylitol guide covers the label names.
- Frozen rawhide. Softens into a swallowable lump.
- Very hard nylon or plastic. No give against a developing jaw, and plastic can crack in the freezer.
- Anything with removable parts.
Redirecting, not stopping
The chewing has to happen somewhere. Your job is to decide where.
Have something ready before you need it. The moment a puppy starts on a chair leg is the wrong moment to go and prepare a toy. Keep two frozen at all times.
Interrupt, then redirect. A short noise to break the focus, then hand them the toy. Do not tell them off. They are in discomfort, not defiance.
Put the temptations away. Cables, shoes, bags, remote controls. During the 16 to 24 week window, a tidy house is a cheaper solution than any training.
Watch the mouthing. Puppies chew hands during teething too, and it hurts more than people expect. Same approach: interrupt, redirect to something cold, and stop the game if the mouthing continues.
Do not offer your fingers as relief. It feels kind and it teaches a habit that is much harder to remove at six months.
The dental angle
Teething is also the point at which you should start thinking about the next fifteen years of your dog's mouth.
Start brushing during teething, gently, with dog toothpaste and a soft brush. The habit matters more than the technique at this stage.
Check for retained baby teeth. If a baby tooth is still there alongside an adult tooth at around seven months, that is worth raising with your vet. Retained teeth trap food and plaque and can cause bite problems.
Expect a little blood. Small amounts of blood on toys or on the floor during teething is normal. Persistent bleeding, swelling or a puppy who stops eating is not, and warrants a call.
Do not rely on chewing alone for dental health. Our post on frozen treats and dental health separates what chewing does and does not do for teeth.
When to call the vet
Teething is uncomfortable and normal. These are not.
- Refusing food for more than a day.
- Persistent bleeding rather than occasional spots.
- Significant facial swelling.
- Bad smell from the mouth.
- A tooth broken rather than shed.
- Baby teeth still present at seven months.
- A puppy who seems in real pain rather than mildly irritable.
Safety, honestly
Puppy teeth are sharp and puppies are persistent, so a few points that matter more at this age than any other.
These are food enrichment toys, not unsupervised chews. Freezbone's own guidance is that once the food is finished, some dogs move on to chewing the rubber itself, and the toy should be taken away at that point rather than left down. That applies doubly to a teething puppy.
Watch the first several sessions with any new toy or shape.
Check for damage every time. Any piece missing means the toy goes in the bin. Swallowed rubber causes obstructions.
Size correctly. Too small is a swallowing risk. Too large and the puppy cannot engage with it.
Take it away once the food is gone, and save it for the next session. This also makes the toy more interesting next time.
Single-ingredient options from the treats and refills range are useful once your puppy can handle firmer texture, and they remove the label-checking problem completely.
A routine for the peak weeks
During 16 to 24 weeks, most puppies do best with:
- Morning: breakfast from a frozen toy rather than a bowl.
- Midday: a chilled carrot or a small frozen fill.
- Late afternoon: the difficult hour for most puppies. A full frozen fill.
- Evening: a second fill during the family's wind-down time.
Three or four toys in rotation makes this possible. Two is not enough once you are running several sessions a day and washing between them.
Frequently asked questions
When do puppies start teething? Baby teeth erupt from around three weeks. The phase owners notice, when adult teeth push through, starts around 12 to 16 weeks.
When does puppy teething stop? Most puppies have all 42 adult teeth by six to seven months, and teething is over by then.
What is the worst week for puppy teething? The 16 to 24 week window, when canines and premolars erupt, is generally the most intense.
Are frozen toys safe for teething puppies? Yes, with a soft frozen fill inside a flexible rubber toy, supervised. Avoid ice cubes and hard frozen objects, which can damage developing teeth.
Can I give my puppy ice cubes for teething? Better not to. They are too hard for developing teeth and can be a choking hazard. A frozen fill inside a soft rubber toy achieves the same cooling more safely.
Is it normal for a teething puppy to bleed? Small amounts of blood on toys is normal. Persistent bleeding, swelling or refusing food is not, and warrants a vet visit.
My puppy is chewing everything. Is this teething or bad behaviour? At 16 to 24 weeks, it is almost certainly teething. Redirect rather than correct, and put temptations out of reach.
Should I give soft food while my puppy is teething? Usually unnecessary. Most puppies eat normal puppy food throughout. If yours stops eating, speak to your vet.
General information, not veterinary advice. Speak to your vet about your puppy's dental development, particularly if baby teeth are still present at seven months.
