Every brochure makes the puppy first week home look like a Christmas advert: a tiny golden retriever sleeping on a folded blanket, sunbeam, smiling family, done.
The real version is closer to a hostage situation, and most of the marketing around new puppies is — to put it generously — lying to you. The cute photos sell food, beds, and "starter kits". They do not prepare you for 2 a.m. crying, slate-coloured diarrhoea on the rug, or the exact moment you realise an eight-week-old puppy can clear a dining-room chair.
This is the version of the first week home written for people who actually have a puppy chewing their ankle right now. We'll cover what to prep before pick-up, what day one and the first night really look like, a feeding and vet timeline, the socialisation window (this matters more than people think), and a clear list of what's normal vs. what means call the vet.
Short paragraphs, no fluff. You're reading on a phone with a puppy in your lap. We see you.
Before the puppy arrives: the real prep list
Most "new puppy checklists" are 80% affiliate links. Here's what you actually need before pick-up day, separated from the upsell.
Puppy-proof more than you think you need to
Get on the floor. Crawl through every room your puppy will have access to. You're looking for:
- Cables, chargers and anything dangling. They will chew it.
- Houseplants — many common ones (lilies, sago palm, pothos, dieffenbachia) are toxic to dogs. The Dogs Trust and Blue Cross poisonous-plant lists are the source of truth here.
- Shoes, socks, AirPods, children's toys with small parts. All of it goes up.
- Kitchen bins with swing lids — they're not puppy-proof. Use a cupboard with a child lock or a step-bin with a heavy lid.
- Loose rugs that bunch (slip risk for tiny legs and house-training stains).
- Stair gates at the top and bottom. Puppies don't have depth perception sorted yet.
Do this once, properly, before they arrive. You will not have time to do it later.
What to buy (and what to skip)
Buy:
- A correctly sized crate (just big enough for them to stand up, turn around, and lie down — bigger means they'll toilet in one corner and sleep in the other).
- Two ceramic or stainless-steel bowls. Plastic harbours bacteria and stains.
- A flat collar with an ID tag (yes, on day one).
- A 1.2–1.8 m lead. Skip the retractable; you can't teach loose-lead walking on one.
- An enzymatic cleaner. Regular cleaners don't break down urine proteins, and your puppy will sniff out and re-mark any spot you didn't fully neutralise.
- The exact food the breeder/shelter has been feeding. Buy a small bag. You'll transition later — not on day one.
- One soft puppy toy, one rubber chew toy, one rope toy. That's plenty.
Skip (or wait):
- The full "starter kit" bundle from a pet retailer. You're paying a premium for products you may never use.
- A bed. Most puppies destroy their first bed inside a month. Use folded towels or an old blanket until they're past the chewing-everything phase.
- The boutique harness. Get a basic, fitted one once they grow a bit (see our harness buyer's guide).
- Anything labelled "calming" with no clinical evidence behind it.
Day one: the first 24 hours
Keep it boring. Genuinely.
When you bring the puppy home, take them straight to the spot in the garden you want them to use as their toileting area. Stand there. Wait. When they go, calm praise — not a parade. Then bring them inside.
Let them explore one or two rooms, on lead, with you. Don't invite the neighbours over. Don't pass them around the family for photos. The single most useful thing you can do on day one is let your puppy down-regulate. They've just been removed from their littermates and the only environment they've known.
Offer a small meal a couple of hours after arrival. Many puppies won't eat much that first day. That's normal — stress suppresses appetite. Worry only if they go more than 24 hours without eating, or refuse water.
Keep introductions to existing pets short, neutral, and on lead. The cat does not need to meet the puppy on day one. Neither does Nan.
The first night: why nobody sleeps
The first night is brutal. Set your expectations there.
Your eight-week-old puppy has never slept alone. They've been in a pile of warm siblings every night of their life. Tonight they're alone in a quiet room with a crate. They will cry. Most cry for 30–90 minutes the first few nights. Some longer.
What helps:
- Put the crate in your bedroom, next to your bed. They can hear you breathe and smell you. This single change cuts crying time dramatically and does not create dependency — you'll move the crate later if you want to.
- A worn t-shirt of yours in the crate.
- A ticking clock or low white noise can mimic littermate body sounds.
- Take them out for one toilet break in the middle of the night for the first one to two weeks. An eight-week-old physically cannot hold it for eight hours. The rough rule: months of age + 1 = max hours they can hold a full bladder, capped at about six.
What does not help: shouting, banging the crate, or letting them out every time they cry. You're trying to teach "crate is calm" — coming out only when quiet (even briefly) is the win.
You will be tired. That's the whole first week. It does ease.
Crate training without the tears (mostly)
The crate is not a punishment box. Treated right, it becomes the puppy's den — a place they go willingly to sleep.
A simple early protocol:
- Feed every meal in the crate, door open at first. They learn: crate = good things.
- Toss high-value treats in randomly throughout the day. They wander in to investigate; you say nothing, let them leave.
- Once they're going in willingly, close the door for 30 seconds while they eat. Build up.
- Cover three sides of the crate with a light blanket (not over the door, so airflow stays open). It cuts visual stimulation.
- Do not use the crate for more than three to four hours at a stretch in the daytime in week one. Bladder, sanity, and the whole "crate = den, not jail" thing all break if you do.
If your puppy panics — non-stop screaming, foaming, frantic biting at bars — back off and rebuild slower. That's distress, not stubbornness.
Feeding schedule for an 8–12-week puppy
This is age-specific, so don't use schedules written for older puppies.
- 8–12 weeks old: four meals per day. Roughly 7 a.m., 11 a.m., 3 p.m., 7 p.m.
- 3–6 months old: drop to three meals per day.
- 6+ months: usually two meals per day.
Use the food the breeder or shelter has been feeding for the first one to two weeks. If you want to switch, do a 7-day gradual transition: 25% new / 75% old → 50/50 → 75/25 → 100%. Faster transitions are the #1 reason new puppies get diarrhoea.
Ignore the bag's feeding chart as gospel — it's a starting point, often calorically generous. Look at your puppy's body condition: you should be able to feel ribs easily under a thin layer of fat, see a tucked waist from above. Adjust portions, not panic.
The first vet visit: what to ask, what to skip
Book the first vet visit for within three to seven days of bringing the puppy home. Even if your puppy seems fine. You're getting a baseline.
At this visit, expect: weight, heart and lung listen, eye/ear/mouth check, faecal sample for worms (bring one fresh from that morning), discussion of vaccines and parasite prevention, and a microchip if not done already (microchipping is legally required for dogs in the UK and across most of the EU).
Vaccine schedule, generally: DHP (distemper, hepatitis, parvovirus) primary course at ~8 and 10–12 weeks, then a booster, plus L4 leptospirosis. Kennel cough (Bordetella) is sometimes added based on lifestyle. Rabies is usually only required if you'll travel internationally — discuss timing with your vet. Ask your vet what's actually risk-relevant in your postcode rather than accepting the full "resort vaccine package".
Good questions to ask:
- What parasite prevention do you recommend for my postcode, and why?
- When can my puppy safely meet other dogs?
- What's a realistic adult weight estimate?
- What signs would mean I should bring them back early?
Skip the upsells you don't understand. "Wellness packages" can be fine value or pure margin — ask what's included and whether you actually need each line item.
The socialisation window: what's actually at stake
This is the section the brochure version usually skips. It matters most.
Puppies have a critical socialisation window roughly between 3 and 14 weeks of age. Inside that window, novel experiences shape their adult temperament. Outside it, the brain shifts — neutral things start being categorised as scary by default. Veterinary behaviourists, including the European Society of Veterinary Clinical Ethology (ESVCE) and the BVA, are clear: under-socialised puppies become the fearful, reactive adult dogs that fill behaviour caseloads.
The tension: your puppy is not fully vaccinated yet. You're told to keep them off the ground in public.
The modern, evidence-based take (consistent across ESVCE, BVA and the American Veterinary Society of Animal Behavior position statements): the risks of under-socialisation outweigh the parvo risks for most puppies, if you socialise smartly. That means:
- Carry them into low-risk environments — friends' homes, dog-friendly cafés, outside the school gates at pick-up time — and let them watch the world.
- Set up controlled meetings with vaccinated, friendly adult dogs.
- Expose them to new sounds (hoover, doorbell, traffic, children), surfaces (tile, grass, gravel, metal grate), and people of different shapes, ages, and gear (hats, beards, wheelchairs, prams).
- Skip dog parks and unknown dogs until vaccines are complete.
Socialisation is not just "meeting other dogs". It's structured exposure to the world, on the puppy's terms. Five minutes a day in week one beats nothing.
What's normal vs. what means call the vet
Normal in week one:
- Soft stools the first one to three days (stress + new water + new environment).
- Eating less than usual on day one, eating more by day three.
- Crying in the crate, especially nights 1–4.
- Hiccups, sneezing fits, the occasional zoomie / crash cycle.
- Mouthing and biting hands. A lot. Welcome to teething (peaks around 4–6 months).
Call the vet today:
- Watery diarrhoea lasting more than 24 hours, or any diarrhoea with blood.
- Vomiting more than once, or vomiting plus lethargy.
- Refusing food and water for more than 24 hours.
- Pale gums (should be pink), or sticky/dry gums.
- Coughing or laboured breathing.
- Sudden lethargy — a puppy who was bouncing this morning and is flat by afternoon.
- Any seizure, even brief.
When in doubt, call. Most vet practices have a triage line. Puppies decompensate fast — what looks small can be parvo, hypoglycaemia, or a foreign-body obstruction.
A 7-day checklist for your puppy's first week
Day 1: Pick-up, quiet first day, one or two short toilet trips, crate intro at meals only.
Day 2: Establish the feeding/toileting rhythm. Begin a simple log (when they wee, poo, eat, sleep). You'll see patterns within 48 hours.
Day 3: First short solo crate sessions while you're in the house. Begin name recognition with treats.
Day 4: Vet visit (if booked). Bring a fresh stool sample.
Day 5: First carry-out outing — high street, friend's porch, café terrace. Watch the world.
Day 6: Introduce one new texture/sound at home. Practise 30 seconds of lead time indoors. When you're ready to build on this, our guide to stopping lead pulling gives you the full step-by-step method.
Day 7: Reflect. Review the log. What's working, what's not. Adjust crate timing, feeding amounts, nap schedule. Sleep is winning.
FAQ
How long should a puppy sleep in the first week?
More than you think — 18–20 hours a day is normal at eight weeks. If your puppy seems wild, they're often overtired, not under-exercised. Enforce nap times.
Can I bath my puppy the first week?
Only if necessary. A warm cloth wipe-down is fine. Full baths can wait until they're settled and dry well — chilled puppies get ill fast.
When can I take my puppy on a real walk?
For sustained walks on public ground, most vets say wait until one to two weeks after the final puppy vaccine round (~16–18 weeks). Until then: carry them, use your garden, do controlled socialisation. For how much exercise to build up to once they're cleared, see our exercise-by-breed-and-age guide.
My puppy bites everything. Is something wrong?
No. Mouthing peaks around 8–16 weeks. Redirect to a chew toy every time, every single time. Yelping like a sibling can work; pulling away and ignoring works better for many puppies.
How much should an eight-week-old puppy weigh?
Varies massively by breed. A toy breed may be 0.5–1 kg; a giant breed 5.5–8 kg. Look at growth curves for the specific breed, or ask the vet for a target.
One week in: what comes next
If you've made it to day seven — congratulations, the worst night-waking is usually behind you, and the puppy starts to feel like yours somewhere around the end of week two.
The next month is about repetition. Same crate routine. Same feeding times. Slow socialisation. Short training reps, two or three times a day. The structure you build now becomes the adult dog you'll have for the next decade.
You're not going to nail it. Nobody does. The goal isn't a perfect puppy week — it's a puppy who's had enough boring, predictable days to feel safe in the new world.
