Puppy training works according to five principles that come up in every good guide: positive reinforcement instead of punishment, a fixed rhythm for house training, calm reactions to biting instead of pulling away, a recall that is linked exclusively with positive things, and socialisation in small, manageable doses. None of these rules works overnight. If you apply them patiently, you usually see progress little by little, at the pace that suits your puppy. More important than any single rule, though, is the principle behind them: a puppy does not learn better through fear, but worse.

The imprinting period: the window of time that counts
Between the eighth and the sixteenth week of life, your puppy learns what is normal in his world: people, other dogs, sounds, everyday situations. Whatever he does not get to know during this time is more likely to become uncertainty or fear later on. That does not mean that more is automatically better. Five minutes in a new place where the puppy stays curious and relaxed are worth more than an hour of overload that only makes him freeze. All five rules that follow build on this one idea: the puppy should experience the world as a safe place, not as a place where something unpleasant keeps happening.
Rule 1: Reward what you want to see more often
The most important principle first: reward what you want to see more often, and ignore what you don't want, as long as it is harmless. If your puppy sits down, he gets a treat and a friendly word. Timing is crucial here: the reward has to come within one to two seconds of the desired behaviour, otherwise your puppy will not link the two properly. Many beginners praise too late, only once they have reached for the treat themselves, and then wonder why nothing sticks.
Punishment works in the opposite direction. Shouting, yanking on the lead or shutting the puppy in his basket builds up one thing above all: fear of you. And a fearful dog learns worse, not better, because he is busy avoiding the situation instead of understanding it.
Rule 2: House training on a fixed routine
As a rule of thumb, a puppy can hold his bladder for about as many hours as he is months old, so about two hours at eight weeks. That gives you the routine: out after waking up, after eating, after playing, and in between every one to two hours. Praise happens outside and right away; accidents indoors are wiped up silently with an enzyme cleaner. We have written down the complete four-week plan with a time table, log and the most common mistakes in Getting a puppy house-trained.
Rule 3: React calmly to biting
A puppy does not bite out of aggression; he explores the world with his mouth. Pulling your hand away or shouting at him often makes it worse because it looks like a game. Better: a short, high “ouch”, the way a littermate would squeal, let your hand go soft and still, and stop the game completely for ten to twenty seconds. If your puppy carries on even harder at the high sound, use a calm, low word instead. The full process in four steps is in Puppy biting: teaching bite inhibition.
One limit belongs here: if your puppy growls and goes stiff at the same time, or if he snaps when you touch his food or toys, it is no longer play. In that case, a trainer who works with positive reinforcement will help faster than trying things out on your own.
Rule 4: The recall is always rewarded
The recall is the most important command of all, because later it can decide over safety. The most common mistake: calling the dog's name only when something unpleasant follows, for example nail trimming or getting into the car. The dog then learns that his name announces bad things, and stops responding exactly when it matters.
Instead, call the name only when something good follows: a treat, play, cuddles. Practise indoors first, then in a fenced garden, and only much later outside with distractions. And very important: when the puppy comes to you, he is always rewarded, even if he did something wrong beforehand. Otherwise he links coming with the punishment, not with the incident before it, and the command loses its value exactly where you need it most.
Rule 5: Socialisation in small doses
New stimuli are important, but the dose makes the difference. An overwhelmed puppy yawns, licks his nose, turns away or hides. These are stress signals, not disobedience. So deliberately plan short, controlled encounters, always at a pace where the puppy stays curious instead of hiding. Better five minutes of something new every day than two hours of overload once a week.
Ten situations that really count during the imprinting period:
- a calm, vaccinated, adult dog from the neighbourhood
- a new kind of floor, for example a grating or gravel
- a vacuum cleaner, at first from several metres away
- a child on a bicycle, watched from a safe distance
- an open umbrella
- a car ride of a few minutes
- stairs in an unfamiliar stairwell
- a vet visit just for weighing, without treatment
- a busy pedestrian zone, seen from a distance
- fireworks sounds at a very low volume, from a recording
The five rules at a glance
| Rule | In short |
|---|---|
| 1. Reward instead of punish | Reward within 1 to 2 seconds of the behaviour |
| 2. Fixed routine for house training | Out after waking up, eating, playing and every 1 to 2 hours |
| 3. React calmly to biting | High-pitched “ouch”, pause the game for 10 to 20 seconds |
| 4. Always link the recall with good things | Never connect the name with anything unpleasant, always reward coming |
| 5. Socialisation in small doses | Short, controlled encounters instead of overload |
None of these methods works overnight. Applied patiently, insecurity turns step by step into trust, faster with some puppies, slower with others. That is exactly what puppy training is about: not obedience for its own sake, but a dog that feels safe in its world.
