New puppy checklist: what to buy and what to do in week one

You need less than you think, and the first day should be quieter than you think. Here’s the short shopping list, a realistic first-day timeline and the week-one jobs, all from our DOG 101 guide.

The short shopping list

The ASPCA’s baseline is a warm, quiet resting place off the floor and away from draughts: a crate or dog bed with a clean blanket works well. Beyond that you’re mostly assembling the essentials:

  • Food and water bowls
  • A collar or harness that fits, with an ID tag
  • A lead
  • A first-week supply of whatever the breeder or rescue was already feeding, so you’re not changing food and home on the same day
  • A crate sized for the dog your puppy will become, big enough to stand up, lie down and turn around in, with a divider you move back as they grow

Day one, hour by hour

There’s no official schedule for hour one, but the AKC’s settling-in advice and the ASPCA’s supply guidance give the day a sensible shape:

ArrivalStraight to the toilet spot outside before anything else. A long journey means a full bladder.
First hourOne quiet room only. Water available. No visitors, no other pets yet.
AfternoonShort, calm exploring of one or two more rooms if they seem confident. Follow their pace, not a clock.
EveningFirst meal (the same food they’re used to), quiet play, another trip outside.
BedtimeCrate in your bedroom, a blanket that smells of mum or littermates inside, a small treat for walking in on their own.
Professor Mochi

“I know, I know — you want to show them off immediately. Don’t. A boring first evening is a successful first evening. Save the party for week two.”— Professor Mochi

The crate: a refuge, never a punishment

The AKC recommends putting the crate in your bedroom for the first stretch: your puppy settles faster with you nearby. Give a small treat when they go in willingly, keep it within earshot at night and use it for calm naps. Never force or drag a puppy in, never leave them crated all day, and never use it as a time-out. In the AKC’s words, it should always be “a haven for your pup, not a jail cell.”

Week-one jobs people forget

  • Book the first vet appointment within the week
  • Order the ID tag and start the microchip registration
  • Choose a “safe zone” for day one, not the whole house at once
  • Agree house rules with everyone at home before the puppy arrives: who feeds, who’s allowed on the sofa, where the puppy sleeps

About the “3-3-3 rule”

You’ll see it everywhere: 3 days to decompress, 3 weeks to learn the routine, 3 months to feel at home. It’s a useful way to set expectations, but it comes from shelter and rescue practice, not from a veterinary body. Use it as a rough model for patience, not as a rule.
