The first six months determine more about the adult dog than any training done later. Most of what owners spend years fixing, fear of strangers, panic at traffic, distress when left, was decided in a window that was open for a few weeks and then closed.
Eight to sixteen weeks: the window
During this period a puppy forms its view of what is normal. Anything it meets calmly now is likely to be unremarkable for life. Anything it never meets, or meets frightening, can take years of work later.
The list worth deliberately covering: people of different ages and appearances, children at a distance before children up close, traffic noise from a safe distance, buses and trams, lifts, stairs, slippery floors, umbrellas, bicycles, pushchairs, vacuum cleaners, thunder and fireworks recordings played quietly, car journeys, being handled by a stranger, being alone.
The essential qualifier is that quality beats quantity. One frightening encounter can undo twenty good ones. The goal is a puppy who notices something new, checks in with you and carries on, not a puppy dragged through a crowded market until it stops objecting.
Ask your vet how to socialise safely before the vaccination course is finished. Carrying a puppy outside, visiting friends with healthy vaccinated dogs and sitting on a bench watching the street are all possible weeks before free walking is.
Luxembourg paperwork, with real deadlines
Three obligations catch new owners out, and all three arrive during this period.
- Microchip and registration. The dog must be identified and declared to the commune within four months of birth. If you acquired the puppy from abroad or from a previous owner, the deadline is one month from the move or the change of ownership
- Rabies vaccination. Given from twelve weeks of age and required for registration
- Civil liability insurance. Compulsory, and usually an inexpensive extension of an existing household policy. Confirm the dog is named
Your commune will also apply an annual dog tax. If you move commune later, you have a month to register at the new one.
Teaching time alone, from week one
This is the most neglected item on the list, and in a city of apartments and long commutes it is the one that creates the most misery later. Start on the first weekend, while the puppy is still tired and while there is no deadline attached.
Begin with seconds. Step behind a door, come back before any complaint. Build irregularly: ten seconds, three, thirty, fifteen. Give a stuffed and frozen toy at departure and remove it on return. Aim for a puppy who can be alone for an hour by twelve weeks, and build from there, rather than a puppy who first meets solitude on the Monday you return to work.
House training
Take the puppy out after waking, after eating, after play and every hour or two in between. Reward outdoors immediately, within a second or two, not when you come back inside. Never punish an accident: it teaches the puppy to hide rather than to hold.
In an apartment this is harder than in a house with a garden, which is why the lift routine matters from the start: harness on inside the flat, straight to the street, no detours, praise on arrival. Expect night-time trips for several weeks, and expect reliability somewhere between four and six months, with occasional regressions during adolescence.
Bite inhibition and mouthing
Puppies mouth. It is how they learn the strength of their jaws, and the lesson is normally taught by litter mates. Your job is to continue it: when teeth touch skin, the game stops for a few seconds, then resumes. Consistency across everyone in the household matters more than the technique, and shouting or holding the muzzle shut tends to make an excitable puppy more excitable.
Provide legal alternatives, several textures of chew, and increase them during teething, which usually runs from around four to six months and produces a noticeable spike in chewing.
Exercise, carefully
The usual guide is roughly five minutes of formal walking per month of age, twice a day. A twelve-week-old puppy therefore gets about fifteen minutes at a time. Free play on soft ground at its own pace is different and is fine.
What to avoid while the growth plates are open: repetitive ball chasing, long runs beside a bicycle, jumping down from heights, and stairs taken many times a day. Large and giant breeds are the most vulnerable and the slowest to finish growing.
Training that actually pays back
Keep sessions to five minutes, several times a day, and pay well. Priorities in order: name response, recall, sit, settle on a mat, walking on a loose lead, and tolerating handling of paws, ears and mouth, which makes every future vet visit easier.
A good puppy class is worth the money if it is well run: small groups, calm introductions, reward-based methods, and an instructor who separates a bullying puppy rather than letting it learn to bully. A badly run class where puppies are allowed to overwhelm each other does real damage in the same window that makes good classes valuable.
Health in the first months
Follow the vaccination schedule your vet sets and keep the passport safe. Worming and parasite prevention start early. Register with a practice before you need one, and ask how out-of-hours emergencies are handled. Discuss neutering rather than assuming a date, since current advice varies with breed and size and for larger dogs is often later than people expect.
The first week, in order
A short list that prevents most of the early chaos: register with a vet and book the first check, confirm the microchip details show you and a working telephone number, add the puppy to your liability insurance, agree the house rules with everyone in the household, including whether furniture is allowed, and decide where the puppy sleeps before the first night rather than at midnight.
Then start three things on day two, not day thirty: brief absences, handling of paws and ears, and calm time in a pen or crate while the household carries on around it.
The months nobody warns you about
Between roughly six and eighteen months, most dogs go through adolescence, and the well-trained four-month-old temporarily forgets its recall, tests the lead rules and becomes selectively deaf. This is normal, it is hormonal and neurological, and the answer is to lower the difficulty, go back to the long line and keep the rules consistent. Owners who conclude the training failed and start punishing usually make the next year harder.
The practical problem for working households
A puppy cannot be left for a working day, and no amount of good intention changes the bladder. The realistic arrangements are time off in the first weeks, a household where someone is home part of the day, or paid cover with short, frequent visits rather than one long absence broken once.
PAWLY covers puppies with short visits rather than long walks: toilet break, a small amount of controlled exposure, handling, water and company, with a report that records what was done and how the puppy coped. The aim in these months is not to tire a puppy out, it is to make sure the hours it spends alone stay inside what it can manage.
