New Puppy Checklist: What You Actually Need First

Every new puppy list runs to forty items. You need about eight, and getting the first fortnight right matters more than any of them.

Before the puppy arrives

Buy these

1. 1Flat collar with an ID tag. Legally required in public in the UK, and it needs your name and address on it. Adjustable, because puppies grow weekly.
2. 2Harness and a 1.8 m fixed-length lead. Not extendable: those teach pulling and give you no control near a road.
3. 3Crate or pen, sized for the adult dog with a divider for now. It's a den, not a punishment, and it does most of the heavy lifting on toilet training.
4. 4Two bowls, stainless or ceramic. Plastic scratches and holds bacteria.
5. 5Whatever food the breeder or rescue was feeding. Change it gradually over a week or more, if at all, in the first month.
6. 6A cheap washable bed. It will be chewed or soiled. Buy the good one later.
7. 7Enzymatic cleaner. Ordinary cleaners leave scent markers the puppy will use again. Buy more than you think.
8. 8A few toys of different types: one rubber chew, one soft, one rope for supervised tugging.

These can wait

• The expensive orthopaedic bed. Adult size, after the chewing phase.
• A coat. Not until the puppy's adult size is clearer, and most puppies don't need one before their first proper winter.
• Grooming kit beyond a soft brush. Introduce handling now; buy the clippers later.
• A car harness or crate, unless you're driving the puppy home, in which case you need it on day one.
• Training treats in bulk. Small pieces of the puppy's own kibble work fine for weeks.

Do these

1. 1Register with a vet and book the first appointment for within a few days of arrival. Ask about the vaccination schedule before the puppy arrives, because it determines what the puppy can safely do and when.
2. 2Sort insurance from day one. Anything that develops before cover starts is a pre-existing condition, permanently.
3. 3Confirm the microchip is registered to you. It's a legal requirement in the UK, and breeders frequently forget to transfer it.
4. 4Puppy-proof at floor level. Get down there and look: cables, small objects, houseplants, bin access, gaps behind appliances.
5. 5Find a puppy class and book it. The good ones fill up weeks ahead, and this is time-critical for a reason covered below.

The socialisation window

This is the part worth reading twice, because it's time-limited and it doesn't come back.

Puppies have a developmental period, roughly three to sixteen weeks, in which new experiences are accepted readily and filed as normal. After it closes, novel things are treated with suspicion by default, and building that acceptance takes far more work for a weaker result.

Most puppies come home at eight weeks. So you have around six to eight weeks of the most important window in the dog's life, and a chunk of it overlaps with incomplete vaccination.

That tension resolves in one direction. Behavioural problems arising from under-socialisation cause far more dogs to be given up or put to sleep than infectious disease does. Don't sit at home until the second jab.

What you can do safely before vaccinations are complete:

• Carry the puppy out. Streets, buses, the school run, outside a supermarket. Traffic noise, buggies, hi-vis jackets, umbrellas, people in hats.
• Visitors at home. Different ages, appearances and voices. Men with beards and deep voices are a classic gap.
• Household noise. Hoover, hairdryer, washing machine, doorbell, fireworks recordings played quietly.
• Meet vaccinated, known-friendly adult dogs in private gardens. Well-run puppy classes require proof of first vaccination for exactly this reason.
• Handling: paws, ears, mouth, tail, being held still. Do this daily, paired with food, and nail trims and vet visits get easier for the next fifteen years.

Quality beats quantity. One calm, positive encounter with a skateboard beats being surrounded by six of them. A frightened puppy is learning the opposite of what you intended.

Toilet training

Out on waking, after every meal, after play, and every hour or two in between. Praise and a treat outdoors, within about two seconds of finishing, so the reward lands on the right behaviour.

Indoor accidents get cleaned with an enzymatic cleaner and no comment. Punishment teaches the puppy to hide where it goes, which is much harder to undo than the original problem.

Expect broadly reliable by four to six months, with regressions around adolescence. Puppies physically can't hold it long: roughly one hour per month of age, so a three-month puppy manages about three hours.

Sleep and settling

The first few nights are hard and they are short. The puppy has just left its litter and is alone for the first time in its life.

Put the crate in your bedroom for the first week or two. It costs you nothing and it prevents a genuinely distressing first experience of isolation, which is worth avoiding for its own sake. Move it out gradually afterwards if you want to.

Exercise, and why less is more

Growth plates are open until somewhere between about ten and eighteen months depending on breed size, and repetitive or high-impact exercise on an immature skeleton causes joint problems that show up years later.

A rough guide is five minutes of formal lead walking per month of age, twice a day. So twenty minutes twice daily at four months. Free play in a garden at the puppy's own pace is different and self-limiting.

Avoid stairs where you can, don't encourage repeated jumping off furniture, and skip long runs and cycling alongside until the dog is fully grown. Mental work tires a puppy far more effectively than distance anyway.

Teething

Adult teeth come through between roughly four and seven months, and it hurts. Biting during this period is not aggression and not a training failure.

Redirect onto something acceptable every time, rather than telling the puppy off. Frozen wet flannels and chilled rubber chews help. Check the mouth occasionally: retained baby teeth, particularly canines that haven't fallen out once the adult is through, need a vet's opinion.

The fortnight-one priority order

1. 1Vet appointment and insurance in place.
2. 2Toilet training routine started from hour one.
3. 3Socialisation begun, carried if not yet vaccinated.
4. 4Sleeping arrangements settled, crate in the bedroom.
5. 5Daily handling practice.
6. 6Puppy class booked.

Nothing on that list is a purchase. That's the point: the shopping is the easy part, and it's the part people spend all their attention on.
