Puppy Teething: Why Cold Helps and What Is Safe at 12 Weeks
The teething timeline week by week, safe frozen fills for each age, and the cold chews to skip.
Around 16 weeks, your puppy starts chewing everything within reach, and it feels like a behavior problem. It is not. Their gums are inflamed, adult teeth are pushing through, and chewing is the only relief they have.
You cannot stop it. You can give it somewhere acceptable to go, and cold is the most effective tool you have.
Cold numbs inflamed gums and brings down swelling. Give a soft-frozen fill inside a flexible rubber toy, supervised, and skip ice cubes, frozen bones and anything sugar-free. Teething peaks at 16 to 24 weeks and is over by about seven months.
When do puppies start and stop teething?
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 |
Why does cold help a teething puppy?
Cold reduces inflammation and numbs tissue, the same reason you put ice on a sprain. During peak teething the gums are sore and sensitive, and something cold and yielding gives real relief.
A frozen fill does two jobs at once: it numbs the gums and it keeps the puppy busy for 20 to 30 minutes.
Frozen is not the same as rock hard. A soft-frozen fill inside a flexible rubber toy is very different from a solid block of ice. Very hard objects can damage developing teeth. Cold and yielding is what you want.
What can a puppy chew at each age?
Match the fill to where your puppy actually is.
8 to 12 weeks: soft and small
- Soaked kibble from their own daily ration
- A teaspoon of plain full-fat yogurt
- 100% pumpkin purée or mashed banana
- Freeze 2 to 3 hours, not overnight
12 to 16 weeks: add texture
- Kibble packed tighter
- Pumpkin at the back, yogurt in the middle
- A few frozen blueberries or green beans
- Freeze overnight now
16 to 24 weeks: the peak
- Freeze everything solid, overnight
- Layer properly so it lasts
- Two or three sessions a day
- Rotate shapes so it stays a puzzle
6 months on: keep going
- Teething ends, chewing does not
- Adolescent chewing runs on boredom
- Keep frozen fills in the weekly routine
Freezbone tip
A small FreezBone holds up to 45g of filling, more than an eight-week-old needs in one go. Fill it partly, and take the fill out of their measured daily food so you are not adding extra.
Which cold options are safe, and which are not?
Safe
- Purpose-made rubber toys with a frozen fill
- A frozen damp washcloth, supervised, thrown out once it frays
- 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 and a choking risk
- Frozen bones: they splinter
- Anything sugar-free: xylitol is dangerous in small amounts
- Frozen rawhide: softens into a swallowable lump
- Very hard nylon or plastic, which can crack in the freezer
- Anything with removable parts
Xylitol hides in some yoghurts, peanut butters and sugar-free honey. Our xylitol guide lists the label names to look for.
How do I stop my puppy chewing the furniture?
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 over the toy. Do not tell them off. They are in discomfort, not defiance.
Put temptations away. Cables, shoes, bags and remote controls. During the peak weeks a tidy floor is cheaper than any training.
Do not offer your fingers. It feels kind, and it teaches a habit that is much harder to undo at six months. If mouthing continues, stop the game and redirect to something cold.
If you are also crate training, frozen toys make the crate the best place in the house. Our crate training plan covers the first two weeks.
A daily routine for the peak weeks
| When | What to give |
|---|---|
| Morning | Breakfast from a frozen toy instead of a bowl |
| Midday | A chilled carrot or a small frozen fill |
| Late afternoon | The hardest hour for most puppies: a full frozen fill |
| Evening | A second fill while the family winds down |
Three or four toys in rotation make this possible. Two is not enough once you run several sessions a day and wash between them.
What about their adult teeth?
Teething is the moment to start thinking about the next fifteen years of your dog's mouth.
- Start brushing now, gently, with dog toothpaste and a soft brush. The habit matters more than the technique.
- Check for retained baby teeth. A baby tooth still sitting next to an adult tooth at around seven months is worth raising with your vet.
- Do not rely on chewing alone. Our post on frozen treats and dental health separates what chewing does and does not do.
When should I call the vet?
- Refusing food for more than a day
- Persistent bleeding rather than occasional spots
- Significant facial swelling or a 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
How to use frozen toys safely with a puppy
These are food enrichment toys, not unsupervised chews. Once the food is finished, some dogs start chewing the rubber itself, so take the toy away at that point and save it for the next session. That matters even more with a teething puppy.
- Watch the first few sessions with any new toy or shape.
- Check for damage every time. If a piece is missing, the toy goes in the bin.
- Size it right. Too small is a swallowing risk; too large and the puppy cannot get at the fill.

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.
Frequently asked questions
-
Baby teeth erupt from around three weeks. The phase owners notice, when adult teeth push through, starts around 12 to 16 weeks.
-
Most puppies have all 42 adult teeth by six to seven months, and teething is over by then.
-
The 16 to 24 week window, when the canines and premolars erupt, is generally the most intense.
-
Yes, with a soft frozen fill inside a flexible rubber toy, supervised. Avoid ice cubes and hard frozen objects, which can damage developing teeth.
-
Better not to. They are too hard for developing teeth and can be a choking hazard. A frozen fill inside a soft rubber toy cools the gums more safely.
-
Small amounts of blood on toys are normal. Persistent bleeding, swelling or refusing food is not, and warrants a vet visit.
-
At 16 to 24 weeks, chewing everything is almost certainly teething. Redirect rather than correct, and put temptations out of reach.
-
Usually not necessary. Most puppies eat normal puppy food throughout. If yours stops eating, speak to your vet.
