New Puppy Checklist: What You Actually Need

It’s the first night home. The puppy is crying in the crate, there’s a puddle on the rug two feet from the pee pad you bought specifically for this, and you’re already wondering what you got wrong.

Nothing. You just didn’t have the full picture yet — almost nobody does on day one.

Every new puppy checklist online seems to disagree with the last one, and the pet store aisle doesn’t help. So here’s a straightforward one, built around what actually sets a puppy up to succeed — not just what’s marketed as “puppy starter” gear.

Why the First Few Weeks Matter So Much

Most new owners think they just need the cute stuff — a bed, some toys, maybe a pen so the puppy has room to play while they’re busy.

What’s actually happening in these first few weeks is that your puppy is forming fast associations: what surface means “bathroom,” what the crate means, what a leash feels like. Some of the most popular starter items quietly work against the habits you’re trying to build.

That’s not a reason to panic — it’s just a reason to be a little intentional about what you bring home first.

The New Puppy Checklist

Walking Gear

Start with a properly fitted harness. It keeps pressure off a growing puppy’s neck and gives them a secure, comfortable way to get used to walking on leash from the very beginning.

Pair it with a properly fitted martingale collar for ID tags and everyday wear. It tightens slightly if pulled, which keeps a puppy from backing out and slipping loose — something a flat collar doesn’t always prevent.

One item most first-time owners don’t think to buy: a bite-resistant leash. Puppies in the teething phase will chew through a standard nylon leash the second you’re not looking, and a chewed-through leash mid-walk is both a training setback and a real escape risk.

Something for the Teething Phase

Puppies need somewhere to put all that chewing energy that isn’t your hands or your furniture. A stuffable Kong is one of the most reliable options — freeze it with something soft inside and it turns into a longer-lasting project that also teaches a puppy to settle and self-soothe.

Setting Up the Crate Right

An airline-safe crate — hard-sided, fully enclosed, with small ventilation openings instead of open bars — is what we recommend by default. There are no gaps for a paw, tooth, or collar to catch on, and the enclosed design feels naturally den-like without needing anything extra.

A lot of owners already have, or prefer, a wire crate — and that’s fine in the right situation. If your puppy doesn’t struggle with separation anxiety and doesn’t actively try to escape or chew at the door, a wire crate can work well, as long as it’s always paired with a fitted crate cover.

The cover needs to be fitted, not loosely draped. A loose cover gives a puppy something to grab and pull into the crate, which turns into a choking or blockage risk fast. A fitted cover also creates the enclosed, den-like feeling that helps a puppy settle instead of reacting to every person and pet that walks by.

Size the crate — and use a divider — so your puppy only has room to comfortably stand, turn around, and lie down, not more. Dogs naturally avoid soiling the space they sleep in, which is a big part of why crate training works for potty training. A crate sized for their full adult body from day one gives them room to potty in one corner and sleep in the other, which undoes that instinct.

One more note on this: if your puppy screams non-stop, won’t settle no matter what, or is actively hurting themselves trying to get out of any crate, that’s a sign to bring in a trainer rather than just switching crate styles.

Potty Training Setup

A potty training bell hung on the door your puppy uses to go outside gives them a way to tell you they need to go, before an accident happens instead of after. Most puppies pick it up faster than owners expect.

You’ll also want a real enzymatic cleaner, not just a household spray. Regular cleaners don’t fully break down the compounds in urine, so puppies can still smell “bathroom” in a spot long after it looks clean — which is often why they keep going back to the same corner.

Why We Don’t Recommend Pee Pads or Diapers

Pee pads teach a puppy that it’s fine to go to the bathroom indoors on a soft surface — which is the opposite of what you’re actually training toward. Some dogs also generalize that lesson to rugs and bath mats, which creates a harder habit to undo than starting outdoor training from day one.

Diapers work a little differently — they mostly manage a mess rather than teach anything and can lead to skin irritation if not changed often. Neither one builds the skill you actually want: a puppy who learns to hold it and signal when they need to go out.

There are real exceptions — very young, not-yet-vaccinated puppies without safe outdoor access, or owners in high-rise apartments, sometimes need an indoor option short-term. If that’s your situation, it’s worth reading the full breakdown before deciding.

Why We Don’t Recommend Playpens

A playpen runs into the same problem as an oversized crate — there’s enough room for a puppy to potty in one corner and rest in another, which works against the instinct that makes crate training effective in the first place.

A pen also doesn’t teach a puppy to settle the way a properly sized crate does. With that much open space, it’s easier for a puppy to pace, bark, and rehearse restlessness instead of learning to relax.

If you want your puppy to have supervised freedom without an open invitation to wander and potty anywhere, a baby gate blocking off a room does the job better — your puppy stays part of the household while you still control the space.

Before → Turning Point → After

Before: Puddles that somehow still land on the rug next to the pee pad, a puppy screaming in a bare wire crate, a leash chewed through by day three.

Turning point: A properly sized, covered crate, a consistent bell-and-outside routine, and a Kong to redirect the chewing.

After: A puppy who settles into the crate without a fight, accidents that drop off within weeks, and walks that stop feeling like a wrestling match.

Common Mistakes

Gear gets you set up — the actual training is what carries you through. If you haven’t read our full guide to the first weeks of puppy training yet, that’s the natural next step.

And if the biting and mouthing phase feels like more than just normal teething, that’s worth its own read too.

FAQ

What should I buy first, before the puppy even comes home?

The crate and the harness. Everything else can be picked up in the first few days, but those two set up the space and the routine from hour one.

Is a wire crate ever okay to use?

Yes, for a puppy who isn’t anxious about being left and doesn’t try to escape or chew at the door — as long as it’s paired with a fitted cover and sized correctly with a divider. An airline crate is just the safer default when you’re not sure which category your puppy falls into yet.

When can I stop using the potty bell?

Many puppies phase off it naturally as they mature, though plenty of owners just keep using it — a dog who can ask to go outside is genuinely convenient for years.

Key takeaway: This checklist isn’t about buying more — it’s about buying smarter, so the next few months of training have something solid to build on instead of working against you.
