Bringing a puppy home is equal parts joy and mild chaos. The good news: that first week sets the tone for everything that comes after. Get the basics right now — routine, crate, food, potty, a little socialization — and the next six months will be genuinely easier. Get them wrong and you'll be untangling habits that are much harder to change once they're set.
This guide covers exactly what to do, day by day, hour by hour, through the first seven days. Keep it on your phone. You will need it at 2 a.m.
Day 1: The Arrival Routine
The single most important thing you can do on day one is keep things calm and predictable. Your puppy just left their littermates, their mother, and every smell they have ever known. Everything is overstimulating — even the good stuff.
When you get home:
- Take your puppy straight to the outdoor potty spot before you go inside. This is the first repetition of a habit you want burned in by week four.
- Give them ten to fifteen minutes to sniff and settle before introducing them to the house.
- Limit the zone. Don't let a new puppy roam a whole house on day one. A kitchen or a single living area with a baby gate is plenty. Less space = fewer accidents, less anxiety.
- Keep greetings short and quiet. Even if you have kids who are thrilled, rotate introductions and keep the energy low.
- Show them the crate before bedtime — propped open, with a treat or two inside. Don't close it yet.
That evening, expect whining. It's normal and it does not mean your puppy is traumatized. They are adjusting. See the crate section below for how to handle it.
What to have ready: A designated sleeping area (crate or playpen), food and water bowls, the same food the breeder or shelter was using, and a collar with an ID tag. See our essential puppy gear checklist for the full setup list.
Introducing the Crate
The crate is not a punishment and it is not optional if you want a dog that is calm, safe, and housetrained. It is a den — a place that belongs entirely to your puppy. The goal is for them to want to be in it.
Crate introduction sequence (spread over days 1–3):
- Day 1: Feed meals near the crate. Toss treats inside and let them go in voluntarily. Don't close the door.
- Day 2: Close the door for thirty seconds while they eat a treat. Open it before they fuss. Increase duration gradually throughout the day.
- Day 3: Try a ten-to-fifteen minute crate nap with a stuffed Kong or chew. Stay in the room.
By night three, most puppies tolerate the crate for two to four hours before needing a potty break.
Night one: Set an alarm. A young puppy (8–10 weeks) can hold their bladder for roughly two to three hours overnight — plan on at least one middle-of-the-night trip out. Carry them straight from the crate to the potty spot, no detours, no play. Treat and praise when they go, then straight back to bed.
Crate size: Just big enough to stand up and turn around. Too big and they'll use a corner as a bathroom. Most wire crates come with a divider — use it.
What not to do: Don't put the crate in an isolated room on night one. Next to your bed, or within earshot of wherever you sleep, is better. Your puppy needs to hear you breathing; you need to hear them asking to go out.
The Feeding Schedule
Puppies under six months need three meals a day, not two. Their blood sugar drops faster than an adult dog's and they can't eat enough at one sitting to sustain them between long gaps.
Sample daily feeding times:
- 7 a.m.
- 12 p.m.
- 5 p.m.
Don't free-feed (leaving food out all day). Scheduled meals make potty timing predictable: most puppies need to go out within five to fifteen minutes of eating.
What to feed: Start on whatever the breeder or rescue was using, even if you plan to switch. Abrupt food changes cause diarrhea. If you want to transition to a new food, do it gradually over seven to ten days — replace about 25% of the old food with the new every two to three days.
Water: Available all the time during the day; pick it up about two hours before bedtime to help reduce overnight accidents.
Treats: Keep training treats tiny (pea-sized). Treats count as calories — if you're doing a lot of training, reduce meal size slightly so your puppy doesn't get chunky in week one.
Potty Training Basics
Housetraining is a numbers game: the more trips outside you catch, the faster it clicks. In the first week, that means going out constantly — and that's fine.
The simple rule for how often:
Take your puppy out:
- First thing every morning
- After every meal (within 5–15 minutes)
- After every nap
- After every play session
- Before every crate session
- Last thing at night
- In between, every 45–60 minutes for a very young puppy
The age-plus-one guideline says a puppy can hold their bladder for roughly as many hours as they are months old, plus one — so a 2-month-old puppy gets about three hours max in ideal conditions. Use this as an upper limit, not a target.
When they go outside: Mark the behavior the moment they squat — a quiet "yes" or a click — and treat immediately after, not when they trot back to you.
Accidents inside: Clean them up thoroughly with an enzymatic cleaner (→ [AFF-SLOT: enzymatic cleaner]) — regular household cleaners don't fully break down the scent markers that draw puppies back to the same spot. Puppy pads (→ [AFF-SLOT: puppy pads]) can work as a bridge if you live in a high-rise or can't get outside quickly, but be aware they can extend the total training timeline if used long-term.
Never: Scold or rub their nose in it. The puppy cannot connect your reaction now to something they did sixty seconds ago. You'll just teach them to be afraid of you near the mess — or to hide where they go.
The Socialization Window
This is the most time-sensitive thing in this guide. Read it.
Puppies have a critical developmental window — roughly from three to sixteen weeks of age — during which their brains are wired to approach new experiences with curiosity rather than fear. After about fourteen weeks, that window begins to close. New sounds, people, surfaces, and animals become harder to normalize the later a puppy first encounters them.
Most puppies come home at eight weeks, which means you have roughly six weeks to work with.
What this means practically: every positive experience you give your puppy in this window pays dividends for the rest of their life. Every experience you skip is harder to add later.
Safe ways to socialize before full vaccination:
- Carry your puppy in arms or a bag in public places — they're taking in the sights and sounds without paw-to-ground contact
- Invite vaccinated, calm adult dogs to your home
- Enroll in a puppy class that requires proof of vaccination for all attending dogs (the American Veterinary Society of Animal Behavior [AVSAB] recommends puppy classes beginning at 7–8 weeks, with at least one round of vaccines and a deworming done before the first class)
- Expose them to different surfaces (grass, gravel, tile, hardwood), sounds (traffic, thunder recordings at low volume), and people (hats, beards, strollers, children)
A puppy socialization guide can help you read whether your puppy is curious versus overwhelmed — the signs are subtle but important.
When to Call the Vet
Schedule your first vet visit within the first week of bringing your puppy home — don't wait for something to go wrong. That visit starts your puppy's vaccination schedule and gives you a baseline health check.
In the meantime, call or go in immediately if you see:
- No eating for more than 12–24 hours, or visible weakness alongside a skipped meal
- Repeated vomiting (occasional spit-up is normal; several episodes in a day is not)
- Watery, bloody, or mucus-heavy diarrhea — especially combined with vomiting or lethargy
- Lethargy that persists after a nap — puppies sleep a lot (up to 18–20 hours a day is normal), but a puppy that is limp or unresponsive when awake is not just tired
- Pale, blue, or white gums — emergency
- Straining to urinate or crying while going — possible urinary issue
- Sudden swelling, hives, or difficulty breathing after vaccines — vaccine reaction, call immediately
Puppies' immune systems are still developing, which means infections move faster in them than in adult dogs. When in doubt, call. Your vet would rather take a non-emergency call on a Tuesday afternoon than see a puppy who waited through the weekend.
One More Thing
The first week is the hardest. You'll be tired, you'll have at least one indoor accident you didn't expect, and there will be a night or two where you question the whole decision. That's all normal.
What makes the difference at week one is consistency, not perfection. Every time you take your puppy outside, reward them in the crate, and keep the feeding schedule the same — you're building a dog that trusts the world is predictable.
