New Puppy Checklist: Everything You Need Before Day One

Bringing a puppy home without the right supplies is like starting a road trip without fuel. You’ll get about 20 minutes in before everything falls apart.

This checklist covers every item you need before your puppy walks through the door, organized by priority. Buy the essentials first. Add the nice-to-haves as your budget allows. Skip the unnecessary stuff the pet store will try to sell you.

Essential Supplies

These are non-negotiable. Have them set up and ready before your puppy arrives.

Crate

A crate is your puppy’s safe space, house training tool, and management solution all in one. Choose a wire crate with a divider so you can adjust the size as your puppy grows, or buy the size appropriate for their adult weight.

Sizing guide:

Small breeds (under 25 lbs adult): 24-inch crate
Medium breeds (25-50 lbs adult): 36-inch crate
Large breeds (50-80 lbs adult): 42-inch crate
Giant breeds (80+ lbs adult): 48-inch crate

See our crate training guide for setup and training instructions.

Food

Get whatever food the breeder or rescue was feeding your puppy. Sudden diet changes cause digestive upset — exactly what you don’t need during the first week. If you plan to switch foods, do it gradually over 7-10 days after your puppy has settled in.

Food and Water Bowls

Stainless steel is the best choice: durable, easy to clean, and doesn’t harbor bacteria like plastic can. Heavy ceramic works too, especially for enthusiastic eaters who push lightweight bowls across the floor. Get two food bowls and one water bowl.

Collar, Leash, and ID Tag

A flat nylon or leather collar with a buckle or snap closure. Measure your puppy’s neck and add two inches. You’ll replace this several times as they grow.

A standard 6-foot leash. Nylon or leather. Avoid retractable leashes — they teach pulling and offer minimal control.

An ID tag with your phone number is essential from day one. Even before microchipping, a tag is your puppy’s fastest ticket home if they escape.

Enzymatic Cleaner

Not regular cleaner. Enzymatic cleaner specifically breaks down the proteins in urine and feces that standard cleaners leave behind. If your puppy can still smell where they had an accident, they’ll use that spot again. This is arguably the most important purchase on this list for successful house training.

Poop Bags

Buy in bulk. You’ll use more than you think.

Treats

Small, soft training treats your puppy can eat in one second. You want treats that reward quickly without interrupting training momentum. Avoid large, crunchy biscuits for training — they take too long to chew.

Good starter options: freeze-dried liver, small commercial training treats, tiny pieces of boiled chicken.

Chew Toys

Puppies need to chew. Provide appropriate outlets or they’ll choose your furniture. Essential starter toys:

A Kong (stuff it with treats or peanut butter)
A rubber chew toy sized for puppies
A rope toy for tug
A soft toy for comfort

An assortment of puppy-safe toys including a Kong, rope toy, and rubber chew toys

Puppy-Proofing Your Home

Before your puppy arrives, get on your hands and knees and see your home from puppy height. Everything at mouth level is a target.

Room by Room

Kitchen:

Secure trash cans with lids or store inside a cabinet
Move cleaning supplies to high shelves or locked cabinets
Check for accessible food (especially chocolate, grapes, onions, and xylitol-containing products)

Living room:

Secure or cover electrical cords
Move shoes, remote controls, and children’s toys out of reach
Check houseplants — many are toxic to dogs (lilies, pothos, sago palm, aloe vera)
Anchor bookshelves and TVs if your puppy could knock them over

Bathroom:

Close toilet lids
Move medications to high shelves
Remove accessible toilet paper rolls (a puppy’s dream toy)
Keep the door closed when not in use

Bedroom:

Pick up clothing, socks, and underwear (common swallowing hazards)
Move phone charger cables out of reach
Check under the bed for small objects

Garage/yard:

Store antifreeze, pesticides, and fertilizers in sealed, elevated containers
Check fencing for gaps — puppies can squeeze through surprisingly small holes
Remove or fence off toxic plants
Pick up small rocks, sticks, and debris

Baby Gates

Buy at least two baby gates to control your puppy’s access to areas of the house. A puppy who has free roam of an entire house will have more accidents, find more dangerous things to chew, and be harder to supervise.

Nice-to-Have Items

These aren’t essential on day one but make life significantly easier in the first few weeks.

Playpen or exercise pen: A portable enclosure that gives your puppy a safe space when you can’t actively supervise. Especially useful in open floor plans where gating off rooms is impractical.

Snuggle toy with heartbeat: A stuffed toy that mimics the warmth and heartbeat of a littermate. Many owners report it helps with first-night crying.

Puppy pads: Useful as a backup, though outdoor house training is generally more effective. Helpful for high-rise apartment dwellers or extreme weather situations.

Grooming basics: A soft brush, puppy-safe shampoo, nail clippers or a nail grinder. You won’t need these immediately, but introducing grooming tools early makes future grooming sessions much easier.

Car safety: A crash-tested crate, car seat, or seatbelt harness for safe travel. Your puppy should never ride unrestrained in a car.

Bitter apple spray: For furniture or objects you can’t move but don’t want chewed. Effective for some puppies, ignored by others.

Training pouch: A small bag that clips to your waist and holds treats for quick access during training sessions.

First Vet Visit Preparation

Schedule your puppy’s first vet appointment within 48-72 hours of bringing them home. Bring:

All medical records from the breeder or rescue (vaccination history, deworming, health certificate)
A fresh stool sample in a sealed bag (for parasite testing)
A list of what food your puppy is eating and how much
Questions you want to ask (write them down — you’ll forget in the moment)

Questions to ask your vet at the first visit:

What’s the vaccination schedule from here?
When can my puppy start meeting other dogs safely?
Is my puppy the right weight?
What flea, tick, and heartworm prevention do you recommend?
When should we discuss spay/neuter?
Are there any breed-specific health concerns I should watch for?
