New Puppy Checklist: The First Supplies You Actually Need in 2026

A puppy needs a den before it needs anything else, and the MidWest iCrate is the pick to build the whole checklist around. A crate is not a cage when it is sized right. It gives a puppy a small, safe place to settle, and it is the backbone of house-training, because most puppies will not soil the spot where they sleep. The listing sizes this 36-inch model for medium-large breeds that reach 41 to 70 pounds as adults.

The divider panel is what makes the iCrate one purchase instead of two. A crate sized for a full-grown dog is too big for an eight-week-old puppy. Give a puppy that much room and it will pick a corner to use as a bathroom. The divider blocks off the extra space so the den stays just big enough to turn around in, and you move the panel back as the dog grows. Two doors let you place the MidWest crate against a wall or in a corner, and the slide-out pan wipes clean after the accidents the early weeks bring.

MidWest Homes for Pets is an established crate-and-pen brand with a real following among owners, so the reputation here is earned rather than invented. The dimensions are still manufacturer-stated, as with any listing. Buy it once, sized to the adult dog, set the divider to puppy size on day one, and the crate grows with the dog instead of landing in a closet in three months.

A crate handles the night; a playpen handles the day. The MidWest exercise pen is the middle step between a locked crate and the full run of the house. It gives a puppy room to move, play, and settle while someone keeps half an eye on it. The listing puts this folding metal pen at 30 inches tall with about 16 square feet of play space, for indoor or outdoor use.

The point of the playpen is supervised freedom. A puppy loose in a whole house is a puppy chewing a cord or piddling behind the couch the moment you look away. Penned into 16 square feet, that same puppy can stretch out, chew a toy, and nap without getting into trouble. The metal panels fold flat in seconds and stand back up with no tools, so the pen can move from the kitchen to the yard and back as the day goes.

There is one honest gap: this MidWest exercise pen has no built-in door, so you lift the puppy in and out until it is big enough to step over a lowered panel. Like the crate, it is a MidWest product with manufacturer-stated dimensions, and a determined climber can scale a 30-inch wall, so watch a bold puppy. Set next to the crate, the exercise pen is the difference between a puppy that is confined and a puppy that is simply contained.

Puppies gulp. A hungry puppy will empty a bowl in seconds, swallow air with the food, and sometimes bring the whole meal back up. The PureDiey slow feeder is the cheap fix. A removable silicone insert set into the bowl breaks the food into small pockets, so the puppy has to eat around the ridges a bite at a time instead of inhaling the lot.

The build is simple and sensible. The bowl is food-grade stainless steel, which resists rust and odor and shrugs off a teething puppy far better than plastic that gets chewed to bits. A non-slip base keeps the PureDiey bowl from sliding across the floor as the puppy pushes at it. The set also includes a lick mat, which spreads a little wet food or peanut butter into a slow, calming puzzle for crate time or nail trims.

PureDiey is a white-label Amazon brand, so the details here come from the listing rather than any outlet test. That is fine for what this is: a stainless bowl with a slow-feed insert in it does one clear job. For a puppy that treats every meal like a race, the slow feeder turns a 20-second gulp into a few minutes of steady eating, which is easier on a small stomach.

A flat collar is fine for holding an ID tag. It is the wrong tool for a puppy that pulls. A young dog throws its whole weight into the leash, and a collar puts that force straight onto a small, still-forming throat. The PHOEPET no-pull harness moves the pressure to the chest instead. A front clip turns a lunging puppy back toward you rather than letting it drag ahead, which makes early leash lessons calmer for both ends of the line.

The details fit a training harness. A padded top handle lets you steer or lift a puppy in a tight spot, near traffic or on stairs. Reflective trim helps drivers see a small dog on an evening walk. The listing gives it two metal leash rings, front and back, and three adjustable buckles, so the front-clip harness can tighten or loosen as a puppy grows into it.

The PHOEPET harness is a white-label product, and its sizing is manufacturer-stated, so measure the puppy and check the size chart before ordering. The trade-off is honest: a harness is not a magic anti-pull button, and it does not replace teaching a loose leash. What it buys you is a way to practice that skill without leaning on a puppy's neck while it learns.

Between roughly zero and six months, a puppy explores the world with its mouth. Teething makes it worse: sore gums drive a puppy to chew on anything it can reach, which is how table legs and shoes get destroyed. The Pupstages teething stick gives that urge a target. It is built to be frozen, and the cold takes the edge off aching gums while the textured surface gives new teeth something to work on.

The design is meant for small puppy jaws. The teething stick is light and easy to hold, and the listing markets it for puppies 0 to 6 months old — the window when mouthing peaks. Keeping one in the freezer means there is always a cool chew ready when the puppy starts gnawing on the wrong thing. The move is simple: when teeth find a shoe, swap in the Pupstages stick and praise the trade.

Pupstages is a white-label brand, so the claims come from the listing, and at a few dollars this is a low-stakes buy. Supervise chewing and replace the stick when it wears, as with any chew toy. Through the mouthy months, a dedicated teething stick is the difference between a puppy that chews its own toy and one that chews the couch.

The first months bring a run of vet visits — the vaccination series, a wellness check or two, maybe a spay or neuter booking. A loose puppy in a car is a hazard, and a squirming one in your arms in a crowded waiting room is worse. The Henkelion carrier is the simple answer for those trips. It is a soft-sided, collapsible bag rated for pets up to 15 pounds, which covers most puppies through their early months.

The features suit short, frequent trips. Mesh panels on the sides let air move through and let the puppy see out, which keeps a nervous first-timer calmer. A waterproof bottom handles the accidents that stress brings. A shoulder strap and a top handle mean you can carry the Henkelion carrier and still hold a leash, a folder of vet paperwork, or a car door.

The Henkelion pet carrier is a white-label product, and the TSA airline-approved claim is the manufacturer's; confirm the current rules with your airline before flying, since carrier policies differ. Many puppies will outgrow the 15-pound limit, which is the honest catch here. Even so, a soft-sided carrier earns its keep in the exact window it is for: the early weeks of vet visits, when safe, low-stress transport matters most and the dog is still small enough to fit.
