Puppy Teething Age: When the Biting Finally Eases Up

Most of the teething-driven biting eases up by 5 to 6 months old, once a puppy's adult teeth have finished coming in. Teething itself runs from around 3 to 6 months: baby teeth start falling out near 12 to 16 weeks, and the adult set is usually fully in by 6 months. The sharpest, most painful-looking chewing and mouthing tends to peak during that losing-teeth stretch, then drops off noticeably as the adult teeth settle in.

Here's the rough timeline. From 8 to 12 weeks, all 28 baby teeth are already in, and a puppy chews mostly to explore the world, not because their gums hurt yet — this stage is more about curiosity than pain. From about 12 to 16 weeks, the baby teeth start loosening and falling out, gums genuinely ache, and this is usually the heaviest chewing and mouthing phase of the whole first year. From 4 to 6 months, the 42 adult teeth are coming in behind the baby teeth, which can bring a second, smaller wave of chewing. By 6 months, most puppies have a full adult set and the physical need to chew on everything in sight drops off sharply.

One thing worth knowing: biting that continues past 6 months usually isn't about sore gums anymore. If your puppy is still mouthing hands, sleeves, or furniture heavily at 7 or 8 months, that's more likely a learned habit than teething, and it responds to consistent training rather than waiting it out. The two problems look similar but need different fixes.

If your puppy still has visible baby teeth alongside new adult teeth after about 7 to 8 months, or you notice swelling, bleeding gums, or reluctance to eat, that's worth a call to your vet — retained baby teeth sometimes need to be removed so the adult teeth come in straight.

Not sure whether what you're seeing right now is normal teething or something to watch more closely? The day-by-day schedule in the free Puppy's First 30 Days pack lays out what to expect week by week, so you're not guessing at every new stage.

A few patterns show up again and again during this stretch. Chewing tends to spike right after naps and in the evening, when energy and discomfort both peak at once — if you notice your puppy going for shoes or table legs at a predictable time of day, that's usually teething, not defiance. Ice cube trays, frozen wet washcloths, and rubber chew toys made for teething puppies tend to help more than plush toys, since the cold takes some of the edge off sore gums the way it would for a teething baby. And puppies who don't get enough appropriate things to chew during this window often redirect onto furniture, baseboards, and cords instead, simply because the urge to chew doesn't go away — it just finds a target.

It's easy to assume a puppy who's "still teething" at 7 months just needs more time, but that's usually the point where it's worth treating it as a training issue instead. The chewing itself might still happen occasionally as adult teeth finish settling, but the hard, repeated mouthing on hands and clothing is a behavior pattern by then, and it gets better with redirection and consistency, not with waiting.

Breed size shifts this timeline a little. Smaller breeds often finish losing baby teeth and settle into their adult set slightly earlier than large or giant breeds, sometimes by a few weeks, since smaller dogs tend to hit physical growth milestones faster overall. That's a minor difference, not a reason to worry if your puppy's timeline runs a little later than a friend's puppy of a different breed — the 3-to-6-month window covers normal variation across nearly every breed and size.

You'll likely find a few tiny baby teeth around the house during this stretch — on the floor, in a toy, occasionally in food — and that's completely normal, nothing to save or worry about. Just as often, a puppy swallows a loose baby tooth without anyone noticing, which is also harmless. Don't read anything into whether or not you ever actually find one.

Teething is uncomfortable for your puppy and can be frustrating for you, especially in the 12-to-16-week stretch when it's at its worst. It's also temporary. Most owners notice a real, obvious drop-off in chewing intensity within a few weeks of the adult teeth finishing, even if the habit of chewing on things sticks around a little longer out of routine.
