Bringing a puppy home is one of the most wonderful — and most demanding — moments for anyone who loves dogs. Those first months, though, aren't all cuddles: they're the window in which your puppy learns how the world works and how to behave within it. Training him well from the very start, with kindness and consistency, means preventing most adult behaviour problems and building a bond of trust that will last a lifetime.
This guide has just one key word: consistency. A puppy can't understand the rules if they change from day to day, or if they apply to one member of the family but not the others. Agree at home on what is allowed and what isn't, then hold that line with patience.
A puppy feels secure when his environment is predictable. That's why it's best to decide on your house rules straight away and apply them from the first day, not "once he's older": the habits formed as a puppy are the ones that stick.
The most effective and respectful training method is positive reinforcement: rewarding the behaviour you want instead of punishing mistakes. When your puppy does something right — sits, comes when called, toilets outside — reward him at once with a treat, a stroke or a cheerful voice. The reward must come within a few seconds, so that your dog clearly links the action to the reward.
Physical punishment or shouting, by contrast, is counterproductive: it creates fear and anxiety, damages your relationship and often worsens the very behaviours you're trying to correct. A frightened puppy doesn't learn better, he only learns to be afraid. When he gets it wrong, the right approach is to ignore the unwanted behaviour (where possible) and redirect him towards the right one.
Anything your puppy finds genuinely delicious works well as a reward: dedicated treats, but also small pieces of healthy, tasty food. One practical option is to use a little of his meat-based meal — for example a single-protein recipe like those from Pappa Fresh — as a "high-value" reward during training, remembering to subtract it from his daily ration so you don't overdo the calories.
If there's one thing that shouldn't be put off, it's socialisation. The first weeks and months are the period when a puppy is most receptive to new things: positive experiences now make for a balanced, confident adult dog; a lack of exposure, on the other hand, is one of the main causes of fearfulness and reactivity in adulthood.
Socialising means introducing your puppy to the world gradually and calmly: different people, other healthy and well-balanced dogs, city sounds, surfaces, vehicles, everyday situations. The goal isn't to "expose him to everything at once", but to let him have positive, non-traumatic experiences, respecting his pace and never forcing him. A practical tip: always carry a few treats and pair anything new with something pleasant.
Two classics of the first months: toileting and rest.
For house-training, the rule is predictability. Puppies need to "go out" very often, especially after waking, after meals, after play and before bed. Always take your puppy to the same spot outside and, when he goes there, reward him immediately. Accidents in the house are inevitable at first: clean them up without any drama and without scolding your dog, who isn't doing it out of spite at that age.
The crate (or carrier) should become his safe haven, never a place of punishment. Teach your puppy to go in willingly by pairing it with good things: a treat, a toy, calm moments. A dog who loves his own crate copes better with being alone and with rest, and faces travel and vet visits with more composure.
Nipping at hands and clothes is perfectly normal: a puppy explores with his mouth and, at around 3-6 months, is teething. The goal isn't to stop him biting, but to teach him what he may bite. When those little teeth land on your skin, stop the game for a moment and immediately offer a suitable alternative, such as a chew toy. This is how he learns "bite inhibition" and where to channel the need to chew.
Never use your hands for rough-and-tumble play: you risk teaching him that hands are prey to be bitten. Better to channel that energy into structured games — fetch, hunting for hidden treats, simple exercises — that tire the mind as well as the body.
The first cues (sit, come, stay) are taught in short, frequent sessions: a few minutes several times a day works far better than one long lesson that bores your puppy. Use clear words that stay the same, reward every success and always finish on a high, while your dog is still interested.
Remember that communication is emotional too: a puppy reads your tone of voice and body language beautifully. Calm, patience and consistency are worth more than any technique. Training takes time, but the results — a calm, balanced dog who trusts you — repay every minute invested.
Training a puppy in the first months means setting consistent rules from day one, using positive reinforcement instead of punishment, giving absolute priority to calm socialisation, patiently teaching house-training, the crate and bite management, and introducing basic cues in short, fun sessions. With kindness and consistency, you lay the foundations of a bond of trust that will last for the whole of your dog's life.
