Your 3-Month Old Puppy: The Settling-In Stage
A vet's guide to your 3-month old puppy: feeding, the first walks on the ground, training that sticks, and what's normal at this age.

Reading Time: 5 minutes - short read
You've survived the 8-week puppy stage. Your puppy is past two vaccinations, starting to feel like a real dog rather than a small chaotic creature you've recently moved in with. Training is getting real. Routines are sticking. You're finding your feet.
And yet most pet parents at this stage still hit daily "why is my puppy doing this?" moments. The biting, the toilet-training regressions, the sleep changes. These are all normal, and all manageable. This guide covers what to expect at 12 to 14 weeks, what training to actually focus on, and what to do about the pain points.
Three-month-old puppies typically need three meals per day, 14 to 16 hours of sleep, and are not yet ready to walk outside on the ground - most vets recommend waiting until two weeks after the final vaccination at around 16 weeks of age.
Feeding a 3 month old puppy
The main change from 8 weeks is that you can drop from four meals a day down to three. The rest stays similar:
- Three meals a day spaced across daylight hours
- Stay on the same complete and balanced puppy food matched to your pup's breed size. If you do need to switch, transition gradually over 7 to 10 days
- Use the packet feeding guide as a starting point, then adjust to your puppy's body condition.
- Re-check portions every few weeks as your puppy grows. The right amount at 12 weeks is rarely the right amount at 16 weeks
Our guide to how much to feed a puppy has the full age-by-weight breakdown.
Exercise
At 3 months, your puppy isn't ready for walks outside yet. Most vets recommend waiting until two weeks after the third vaccination, which usually happens at around 16 weeks of age. Until then, the world outside (footpaths, parks, anywhere unvaccinated dogs could have been) is a real parvovirus risk. Our guide to when puppies can go for a walk outside has the full picture.
That doesn't mean your puppy can't get out and about. You can:
- Carry your puppy outside to safe places they wouldn't otherwise see - cafes, friends' houses, the school pick-up. Brilliant for socialisation
- Practise lead walking indoors and in the garden, building the foundation for real walks once they start
- Play and explore in the garden if you have one, with plenty of sniffing time
- Continue puppy school in a clean, controlled indoor environment
Once your puppy is cleared for walks, the rule to remember is five minutes of structured walking per month of age, once or twice a day. Worth keeping in mind for the weeks just ahead. The rule matters more for large and giant breeds, whose growth plates are still developing. Over-exercising a large breed at this age can cause real joint problems later. See our guide to how much exercise dogs need for the full breakdown.
What training looks like at 3 months
This is the stage where training actually starts to stick. The priorities:
- Sit - likely already underway, becoming more reliable in different environments
- Recall basics - start in the house, then the garden, always with treats, never call your puppy to you for something they won't like
- Lead walking - short sessions, rewarding any moment your puppy is walking next to you rather than pulling
- Bite inhibition - still the big one, redirect to toys, walk away when play gets too rough
- Name response in distraction - easy at home, harder when there are distractions
Keep sessions short. Five minutes, two or three times a day, is plenty, and every meal is a training opportunity if you use part of it as rewards. Reward-based methods only. Our guide to how to train a puppy covers technique.
Once the basics are reliable, you can start building on them with stay, lie down, leave it, and fun ones like roll over.
Puppy school
If you haven't already, 3 months is still very much within the window to enrol in puppy school. Most classes accept puppies from 8 to 16 weeks. What to look for in a good class:
- Reward-based methods only - no choke/check chains, no "alpha" language, no punishment-based correction
- Small groups - usually around 4 to 6 puppies
- Vaccinated puppies only (most schools require the pup has had at least one vaccination) in a clean indoor space
- A trainer who handles the dogs and educates the pet parents - half the value is the human education
The point isn't really obedience. It's positive exposure to other puppies and people during the socialisation window, in a safe environment.
The 3-month pain points
Three things commonly worry pet parents at this age.
Biting and mouthing is still happening (or has come back). Common around now, particularly when your puppy is overtired or overstimulated. Should be slowly improving over the coming weeks, not getting worse. Redirect to toys, walk away when play gets too rough, and check whether your puppy is getting enough sleep. Overtired puppies bite more, at every age.
Toilet training regressions. Common around 12 to 14 weeks, and almost always a routine problem rather than a training failure. Go back to basics: outside first thing, after every meal, after every nap, after every play session, last thing at night. Reward heavily for going in the right spot. See how to toilet train your puppy for the full method.
Sleep changes. Some puppies start sleeping a bit less at this age but they still need 14 to 16 hours a day. If yours is biting, zooming and refusing to settle, the answer is still usually a nap. Same as at 8 weeks.
3-Month Old Puppy FAQs
Three meals a day, lead practice at home (real walks are still a few weeks away), real training in short sessions, and puppy school if you haven't started yet. The biting, the toilet regressions, the sleep changes are all normal at this age. Stick with routine and reward-based training and the next few weeks will feel like real progress.
