Most puppy training plans fail for the same reason: they are organised by skill when a puppy develops by stage. Teaching a solid stay at nine weeks is wasted effort. Starting socialization at sixteen weeks is too late. And the single most common mistake — getting tougher when a seven-month-old stops listening — happens because nobody told the owner that adolescence was coming.
This is the whole first year, organised by what your puppy is actually capable of at each point, and what closes if you miss it.
The two windows that do not reopen
Almost everything in the first year is recoverable. Two things are not, and they deserve stating before the schedule.
The socialization window closes at around 12 to 16 weeks. This is the period when a puppy forms its baseline expectations about what is normal and safe. The AVSAB is explicit that this window closes at roughly 12 to 16 weeks, and that the risk of a dog developing behavior problems that shorten its life outweighs the risk of infectious disease during that period. Behavior problems, not infection, are the leading cause of death in dogs under three.
Bite inhibition is learned early. A puppy that never learns how hard is too hard, while its jaw is small and the consequences are minor, does not learn it later when it is not.
Everything else can be caught up. These two are worth reorganising your calendar around.
8–10 weeks: arrival
Priority: sleep, toilet routine, and the fact that nothing bad happens here.
Your puppy has just lost its mother and every littermate it has ever slept against. Ambition at this stage is counterproductive.
What to actually do
- Enforce naps. Puppies need roughly 16 to 18 hours of sleep in 24 and will not take it voluntarily. The frantic evening biting that makes owners despair is almost always overtiredness rather than temperament.
- Toilet trips by the clock — roughly every 60 to 75 minutes when awake, plus after every meal, nap and play session. Bladder capacity is about age in months plus one, in hours, as a ceiling.
- Charge a marker word. Say yes, give food. Thirty times over a few days, asking for nothing. This is the foundation every later cue is built on.
- Handling, in seconds. Touch a paw, treat. Look in an ear, treat. This is what makes vet visits and nail trims possible for the next fifteen years.
- Seconds of alone time. Step out of sight for five seconds, return before your puppy notices. Research on separation-related problems identifies regular short absences in puppyhood as a protective factor.
What not to do
No long training sessions, no formal obedience, no dog parks, no hours of visitors. A puppy that is overwhelmed in week one is harder to train in month three.

10–12 weeks: the window is open and closing
Priority: socialization. Everything else is secondary this two weeks.
The goal is neutrality, not enthusiasm. A puppy that greets every person and dog it sees learns that every person is an event — and that is the foundation of the frustrated lead-lunging you see in adolescents. What you want is a puppy that notices things and finds them unremarkable.
The rule that matters more than the checklist
Your puppy should be curious, not overwhelmed. If it freezes, tucks its tail, backs away, or refuses food, you are too close. Add distance.
A frightening experience during this window does more damage than no experience at all. Quality beats quantity every single time.
What to cover
Men with deep voices, beards, hats and hoods, high-vis jackets, walking sticks and wheelchairs, children of different ages, someone running past. Different surfaces underfoot. Traffic at a distance. The vacuum cleaner. Car journeys that do not end at the vet. A visit to the vet where nothing happens.
Carry your puppy if it is not fully vaccinated. Sitting on a bench watching a street is socialization. It requires no paws on the ground.
Also this two weeks
- Sit and down with a lure, two or three minutes at a time.
- Recall as a game indoors. Fun, never used to end anything.
- Wear the harness indoors before it ever attaches to a lead.
- Bite inhibition — the yelp-and-redirect work starts properly now.

12–16 weeks: teething and the last of the window
Priority: finish socializing, survive teething, add the word to known behaviors.
Adult teeth push through from around twelve weeks. Chewing intensifies and it is genuine discomfort rather than defiance.
- Frozen stuffed rubber toys — the single most useful item at this age.
- Fade the lure now. Around repetition six, make the same hand movement with no food in that hand and pay from the other. Fading late produces a dog that only works when it can see food, and it is the most skipped step in dog training.
- Add the cue word — say it once, just before the behavior you can now predict.
- Long line outdoors for recall. Five to ten meters of flat webbing on a harness.
- Loose-lead work in the garden before the pavement.
Related: destructive chewing and teaching sit.
4–6 months: the productive stretch
Priority: proofing. This is the easiest training period of the entire year — use it.
The window has closed, teething is easing, adolescence has not arrived. Puppies at this age learn fast and still want to be near you. Owners who bank progress here have something to fall back on when month seven arrives.
Raise one variable at a time
Duration, distance, distraction. When you increase one, drop the other two back. A puppy that holds a stay for thirty seconds beside you cannot hold thirty seconds while you walk ten paces away — that is not disobedience, you changed two variables at once.
What to build
- Stay, with a release cue. Without a word that ends the behavior, your dog decides when it is over.
- Leave it and drop it as separate cues with separate words — the two most practical things a pet dog can learn.
- Recall on the long line in progressively harder places.
- Settle on a mat — the cue most owners never train and later wish they had.
- House training should be largely reliable somewhere in this range.

6–12 months: adolescence
Priority: hold the line. Do not get tougher.
This is the stage that ends most training plans, and almost nobody is warned about it.
Your dog will stop responding to cues it knew perfectly. Recall will deteriorate. It will appear to have forgotten things. Owners describe it as the dog becoming stubborn, testing boundaries, or trying to dominate.
It is none of those. It is a documented developmental phase. Research on adolescence in dogs found reduced trainability specifically around the onset of puberty, and specifically toward the caregiver rather than toward strangers — which is precisely the pattern owners describe as being personal. The full breakdown of that stage is in our guide to adolescent regression and why your dog stops listening at eight months.
More seriously: this is the age at which dogs are most likely to be surrendered to shelters. The behavior that gets them there is normal and temporary.
What actually works
- Reduce your criteria. Go back to easier environments and shorter durations. This feels like going backwards and it is the fastest route through.
- Raise your reward value. What worked at four months will not compete now.
- Put the long line back on. Every off-lead failure rewards ignoring you.
- Keep sessions short. Five minutes twice a day.
- Do not add corrections. Confrontational techniques produced aggressive responses at high rates in owner surveys, while non-confrontational methods produced them in 0–6% of cases. Adding pressure to an adolescent dog is how reactivity starts.
What else appears now
Second fear periods, lead reactivity, resource guarding, and jumping that had stopped. All are normal at this age, all respond to the same approach, and none of them mean you failed.

Size changes the schedule more than breed does
The ages above are a framework, not a fixed calendar. The single biggest variable is not breed personality — it is size, because size determines how long adolescence lasts. If you would rather work from your own dog’s answers than a generic calendar, our free dog training tools build a schedule and a progress estimate from what you actually report.
Small breeds mature fastest. Adolescence often starts around six months and is largely finished by twelve. But bladder capacity is proportionally smaller, so house training frequently takes longer, and accidents at six months are common rather than a failure.
Medium breeds follow the schedule above most closely.
Large and giant breeds are the ones owners misjudge. A Labrador or a German Shepherd may not be through adolescence until eighteen months, and giant breeds can take until two years. That means the difficult stretch is not four months long — it is a year. Owners who expect it to end at twelve months often conclude the training failed when the dog is simply still adolescent.
Large breeds also need controlled exercise while growth plates are still open. Repetitive forced exercise — long runs, jumping, stairs — is a joint concern in a growing large-breed puppy, and the amount is worth discussing with your vet rather than guessing. Mental work has no such limit, which is one reason it matters more for these breeds.
Working lines need a job, not more walking
Border Collies, Malinois, working-line Springers and similar dogs were selected for stamina and problem-solving. Walking a working-line adolescent further does not tire it — it builds fitness, and you end up with a fitter dog that needs even more.
What tires these dogs is using their brain and their nose. Scentwork, puzzle feeding, and short training sessions do more per minute than distance ever will. Our guide to high-energy breeds covers this in detail.
What to do if you missed the window
Many people read this after adopting a dog at eight months, or a rescue with no known history. The socialization window has closed. That is worth being honest about, and it is not the end of the story.
What you can no longer do is build a broad baseline of “this is all normal” cheaply and quickly. What you can do is change how your dog feels about specific things, one at a time, using distance and food. It is slower, it is more deliberate, and it works.
The method is the same one used for reactivity: find the distance at which your dog can still eat while the trigger is visible, pair the trigger with food, and close the gap over weeks rather than minutes. If your dog will not take chicken, you are too close.
Expect months rather than weeks, expect setbacks, and target a dog that copes rather than a dog that loves everything. For a dog that missed its window, that is a transformed life. See our guide to dogs afraid of strangers.
The one-page schedule
| Age | Main priority | Toilet trips | Sessions |
|---|---|---|---|
| 8–10 wk | Sleep, toilet routine, marker word | Every 60–75 min awake | 2 min × 3–4 |
| 10–12 wk | Socialization — neutrality not excitement | Every 75–90 min | 3 min × 3 |
| 12–16 wk | Finish window, fade the lure, add words | Every 90–120 min | 5 min × 2–3 |
| 4–6 mo | Proofing — the easiest stretch | Every 2–4 h | 5–10 min × 2 |
| 6–12 mo | Hold the line through adolescence | Every 4–6 h | 5 min × 2 |
Why sleep is on this schedule at all
Because it is not a welfare footnote — it is when learning gets fixed.
A study published in Scientific Reports taught dogs new commands in a foreign language and then measured their sleep. Sleep structure changed after the learning session, and dogs that slept after training performed better afterwards.
A puppy that does not sleep enough does not consolidate what you taught it, and it is more frantic and less able to control itself the following day. Enforced naps are training, not babysitting.
The five mistakes that cost the most
- Delaying socialization until vaccinations finish. The window closes first. Carry the puppy, use safe environments, but do not wait.
- Training long sessions. Puppies concentrate for two or three minutes. Frequency beats duration by a wide margin.
- Never fading the lure. Produces a dog that works only when food is visible.
- Getting tougher in adolescence. The exact moment corrections do the most damage.
- Punishing house-training accidents. Teaches the puppy to hide from you when it needs to go, which makes supervision harder and accidents more likely.
When to see a vet rather than train harder
- House soiling with straining, blood, or frequent small amounts — urinary infections are common in puppies
- A puppy that will not settle at all, or panics when left even briefly
- Fear that is getting worse rather than better with careful exposure
- Any behavior that changed suddenly
- Biting that is stiff and silent rather than bouncy and noisy
Pain is a recognized contributor to behavior problems — around a third of dogs referred for behavior work have a painful condition. In a puppy this is easily mistaken for temperament.

Frequently asked questions
What age should you start training a puppy?
The day it arrives, usually eight weeks. Not formal obedience — a marker word, a toilet routine, handling, and seconds of alone time. Puppies are learning from the first hour whether you are teaching or not.
What is the hardest age for a puppy?
Two stages. Weeks 8–12 for exhaustion, and 6–12 months for training, when adolescence causes a documented drop in responsiveness to the owner specifically.
How long should puppy training sessions be?
Two to three minutes under sixteen weeks, five to ten minutes after that, several times a day. A puppy that gets bored has stopped learning and started guessing.
Yes, and you should. The AVSAB position is that the behavioral risk of missing the window outweighs the infectious risk. Carry your puppy, use clean environments and known-healthy dogs, and do not wait for the final vaccination.
Why has my 7-month-old stopped listening?
Adolescence. Research found reduced trainability around puberty onset, directed at the caregiver rather than at strangers. Reduce criteria, raise reward value, and wait it out — do not get tougher.
What commands should a puppy know first?
Name response, a marker word, sit, and recall as a game. Leave it and settle by four to six months. Stay and drop it during the proofing stretch.
When is a puppy fully house trained?
Largely reliable between four and six months for most puppies, with small breeds often later. Accidents up to that point are normal.
Should I use puppy pads?
They teach that eliminating indoors is acceptable, which then has to be untaught. They have a place for apartments and medical restrictions, and otherwise they usually add a step.
This is general guidance and not veterinary advice. Vaccination timing, socialization risk in your area, and any behavior that concerns you should be discussed with your veterinarian, who knows your puppy and your local disease risk.
