Your Puppy's First Week at Home: A Day-by-Day Guide
The week a puppy arrives is one of the most stressful periods of its life. It has lost its mother and its littermates, it is in an unfamiliar place, and it has no idea what the rules are. What you do during those seven days has a disproportionate effect on the years that follow—whether the dog grows up confident or fearful, whether it develops separation anxiety, whether it guards food, whether it can share a house with other animals.
The reassuring part is that the correct approach is not complicated. It comes down to three things: provide safety, establish predictability, and build positive associations.
Before the Puppy Arrives
Do this preparation one to three days ahead rather than on the day.
What to buy. Dog food—and confirm with the breeder or rescue exactly what the puppy is currently eating so you can buy the same thing. Stainless steel or ceramic bowls rather than plastic, which harbours bacteria and gets chewed. Pee pads plus a pen or crate. A cheap first bed, because it will probably be destroyed. A collar or harness and a lead; a harness is better for a puppy because it does not press on the throat. Chew toys, a rope toy, and a puzzle feeder. Nail clippers and a brush. And an enzymatic cleaner, which is not optional—ordinary household cleaner removes the smell for you but not for the puppy, and the residual scent is what draws it back to the same spot.
Home safety, checked from the puppy's height. Get down on the floor and look at the room as a puppy would see it. Cable tidy or protect cords. A lidded bin. Toxic foods moved out of reach—chocolate, grapes and raisins, onions, garlic, xylitol. Lilies and other toxic plants removed. Small objects collected: hair ties, buttons, coins, batteries, pills. Cleaning products, cosmetics, and medicines moved to high cupboards. Gaps checked, including balconies, stairways, and the space under furniture. Toilet lid down.
Agree the rules before the dog arrives. Can it get on the sofa? Is the bedroom allowed? Who feeds it and who walks it? Inconsistent rules across a household are the most common single reason puppy training fails, and the argument is much easier to settle before there is an animal in the room.
Day One: Less Is More
The most common mistake on day one is doing too much. A puppy arriving in a new home is in a state of stress, and its capacity to absorb new experiences is limited. The goal for day one is not training—it is helping the puppy feel safe.
- Take it straight to the toilet area and let it empty out. Reward success calmly and immediately.
- Let it explore a limited area on its own. Do not carry it around the house on a tour, and do not introduce it to every member of the household at once.
- Set up a safe zone—a pen or crate with a bed, water, and a toy. This will be its base for the coming weeks.
- Keep the territory small. One room to begin with, expanded gradually. A puppy given the run of the whole house in week one is difficult to toilet train and hard to supervise.
- Keep visitors away on day one. Every social interaction that feels pressured uses up part of the puppy's coping capacity, and that capacity is finite.
- Let the puppy decide when to approach you. Sit quietly in the same space and wait.
The first night. Put the crate or bed somewhere you can hear it, because most puppies cry. An old item of your clothing in the bed helps—it carries your scent. When it cries, first check whether it needs to toilet, then avoid responding to every single cry, because that establishes "crying brings company". Wait for a few seconds of quiet before going over. A practical solution many owners use is to place the crate beside the bed so the puppy can see you for the first few nights.
Days Two and Three: Build the Toilet Routine
Toilet training is the highest-value work of the first week, and it produces results faster than anything else.
Know when a puppy needs to go. Immediately on waking. Within five to thirty minutes of eating. After play. After drinking. As a general rule a puppy can hold on for roughly its age in months plus one hour—about four hours at three months—and somewhat longer overnight.
The routine. Take it to the spot proactively at each of those moments. Wait quietly; do not play. The instant it goes, praise enthusiastically and give a treat—at the moment it happens, not when you get back inside. If nothing happens within five minutes, return it to the crate or pen and try again in fifteen or twenty minutes.
When there is an accident, do not punish. No rubbing noses, no shouting, no hitting. Clean it up quietly with enzymatic cleaner and then ask yourself whether you missed a moment. Punishment teaches a puppy that toileting in front of a person is dangerous, which produces a dog that hides behind the sofa to go—and a much harder training problem.
Days Three to Seven: Food, Sleep, and the Crate
Feeding. Keep the puppy on its current food for the first week. A change of home plus a change of diet reliably produces diarrhoea. If you do need to switch, do it over seven days: days one and two at 75 percent old food, days three and four at half and half, days five and six at 25 percent old, and the new food alone on day seven. Puppies under three months need three to four small meals a day. Feed to a schedule and pick the bowl up rather than leaving food down, because free-feeding makes toilet training harder and appetite impossible to monitor.
Preventing food guarding is worth doing from the first week. Walk past while the puppy eats and add something better to the bowl—a piece of chicken, a treat. The puppy learns that a person approaching its food predicts something good, which is the opposite of the condition that produces guarding.
Sleep. Puppies need eighteen to twenty hours a day, and this is a fact owners routinely underestimate. An overtired puppy becomes hyperactive, mouthy, and uncooperative—exactly like an overtired toddler. Use a rhythm of roughly an hour awake followed by a compulsory one to two hours of rest in the crate or pen.
Crate training. The objective is for the crate to be a safe den, not a punishment. Put treats and toys inside and leave the door open so the puppy can come and go freely. Feed meals in the crate. Extend the time the door is shut from a second or two upward. Never put a puppy in the crate as a punishment, and never let it out while it is crying—that teaches "crying opens the door". Wait for a few seconds of quiet first.
Socialisation: Do It Before the Vaccinations Finish
This is the most misunderstood point in puppy care.
The socialisation window runs from roughly eight to sixteen weeks. It is the period in which a puppy learns that the world is safe, and what is missed during it is difficult to recover later. The vaccination course typically finishes at around sixteen weeks. The two overlap, which means socialisation has to happen safely during a period when the puppy is not fully protected.
Safe socialisation means carrying the puppy rather than letting it walk. Take it out in your arms and let it see and hear traffic, pedestrians, bicycles, umbrellas, people in hats, children, and other dogs at a distance. Invite healthy, fully vaccinated adult dogs to your home to play—this is the safest and most effective social contact available. Let it feel different surfaces: grass, tile, wood, sand, metal grates. Play recordings of thunderstorms, fireworks, and vacuum cleaners, starting quietly and pairing each with food. Introduce it to people of different ages, genders, and appearances. Handle its paws, ears, mouth, and tail gently, which will make future veterinary examinations and grooming far easier.
What to avoid is letting the puppy walk on the ground in high-traffic animal areas—veterinary practice car parks, pet shops, dog parks, busy public spaces. Avoid contact with dogs of unknown health status and their waste, and prevent it from licking things it finds outdoors.
The principle is straightforward: carry it anywhere, let it walk almost nowhere.
Six Things Not to Do in the First Week
- Do not bathe the puppy. Bathing during the settling period increases the risk of chilling and illness. Wait until it has adapted, usually one to two weeks, and then dry it thoroughly.
- Do not change its food. See above.
- Do not hold a welcome party. Limit the number and intensity of visitors.
- Do not punish toilet accidents. See above.
- Do not over-exercise it. Growth plates are open; avoid long runs on hard surfaces, stairs, and jumping.
- Do not ignore warning signs of illness. See below.
When to Call a Vet Immediately
Puppies deteriorate quickly, so "wait and see until tomorrow" is the wrong instinct.
- Appetite clearly reduced, or not eating at all for more than 24 hours—puppies are at risk of hypoglycaemia
- Vomiting or diarrhoea, which can cause serious dehydration in a puppy within a day
- Lethargy, drowsiness, or unresponsiveness
- Blood or worms in the stool
- Coughing, nasal discharge, or increased eye discharge
- An abnormally distended abdomen, which may indicate parasites or fluid
- Pale gums
- Inability to stand, or an abnormal gait
One further recommendation: book a veterinary visit within three to seven days of arrival for a full health check, a faecal examination for intestinal parasites, and a vaccination plan. A large proportion of puppies carry intestinal worms. That is normal, and it needs treating.

Frequently Asked Questions
My puppy cries at night. Is something wrong?
Crying during the first two or three nights is very common. Once you have ruled out a toilet need, try moving the crate into your bedroom, adding an item of your clothing, wrapping a warm water bottle in a towel to imitate the littermates' body heat, or playing white noise. Do not rush to comfort it the instant it cries, because that reinforces the crying, but do not ignore it for hours either—that can increase anxiety. Wait for a few seconds of quiet, then respond.
What should I do when the puppy bites my hands and feet?
This is normal mouthing plus teething, and it is most intense between three and six months. Do not hit the puppy and do not push it away with your hands, which registers as play. Instead, yelp sharply the moment teeth touch skin, stop the interaction, and turn away for ten to twenty seconds. Offer a chew toy as a substitute. Consistent repetition usually produces clear improvement within one to two weeks.
When can I take my puppy out for a walk?
It depends on the vaccination schedule. Until the course is complete—usually around sixteen weeks—do not let it walk on public ground, but do carry it out to experience the world. Follow your veterinarian's advice, because local disease prevalence varies and recommendations differ accordingly.
Can my puppy meet the adult dog in my house?
Yes, provided the adult dog is healthy and fully vaccinated. This is the ideal social contact. Two rules apply: the first meeting must be supervised, and the adult dog must have somewhere it can go to be alone. Do not let the puppy approach the adult dog while it is eating.
When should training start?
From day one, though the first day's work is limited to simple things like responding to its name and going to the right place to toilet. Formal cue training—sit, wait, come—is best started at eight to ten weeks. A puppy's attention span is only a few minutes, so three to five minutes several times a day achieves far more than a single twenty-minute session.
