The week before a puppy arrives is when most people panic-buy. You end up with a basket full of things you don’t need and, somehow, still no poop bags on day one.
This checklist is the opposite. It’s what actually matters in the first month, organised by when you’ll need it — and written specifically for large and giant breeds, where the wrong-sized purchase is an expensive mistake. A crate that fits a 12-week-old Labrador is useless by June.
Buy the essentials before pickup day. Everything else can wait until you know your dog.
| Category | What you need on day one |
|---|---|
| Sleeping | Crate sized for adult weight, with divider |
| Walking | Flat collar, ID tag, harness, 6-ft leash |
| Feeding | Two stainless steel bowls, puppy food |
| Play | Two or three tough chew toys |
| Training | Soft training treats, poop bags |
| Cleanup | Enzymatic cleaner |
1. Where your puppy will sleep
A crate — buy adult-sized, not puppy-sized. This is the single most important purchase on the list and the one people most often get wrong. Don’t buy a small crate now and a bigger one in six months. Buy the size your dog will need as an adult and use the divider panel to block off the extra space while they’re small, moving it back every few weeks as they grow.
For a Labrador or Golden, that’s a 42-inch crate. For a German Shepherd or Rottweiler, 48 inches. For a Great Dane, 54.
We compared the options in detail in our guide to the best dog crates for large breeds — it includes a sizing table by breed.
A bed — but a cheap one first. Large-breed puppies destroy their first bed with remarkable consistency. Start with something washable you won’t mourn, and buy the orthopedic bed once the teething phase is over.
2. Walking and identification
A flat collar and an ID tag. The tag should go on before your puppy leaves the breeder or shelter, not a week later. Put your phone number on it — not the dog’s name.
A harness. For a dog that will eventually outweigh a small adult, a harness spreads pressure across the chest instead of the neck, which matters enormously once they start pulling. Get an adjustable one so it grows with them, and re-check the fit every few weeks. Our picks are in the guide to the best harnesses for large breeds.
A standard 6-foot leash. Not a retractable one. Retractable leashes teach a dog that pulling extends their range — precisely the habit you don’t want in a 90-pound adult.
3. Feeding
Two stainless steel bowls. One for food, one for water. Stainless is the right call: it doesn’t harbour bacteria the way plastic does, survives being flung across a kitchen, and goes in the dishwasher. Look for a non-slip rubber base — a big puppy pushes a lightweight bowl around the room while eating. A 32 oz size suits most large breeds from puppyhood onward.

Puppy food — large-breed formula specifically. This one genuinely matters. Large-breed puppy foods are formulated with controlled calcium and calorie density to slow growth slightly, which reduces the risk of joint problems later. Ask the breeder or shelter what the puppy is currently eating and buy that first — switching food on day one, on top of everything else, is a recipe for an upset stomach. Transition gradually over a week if you want to change.
4. Toys and chewing
A teething puppy will chew. Your job is to make sure they chew the right things.
A stuffable rubber chew toy. The classic KONG is on this list for a reason: it survives serious chewing, and stuffed with a little food and frozen it will occupy a puppy for far longer than any squeaky toy. Buy two so one is always in the freezer.

Two or three other textures. A rope toy, something soft, something hard. Rotate them weekly rather than leaving all of them out — toys stay interesting much longer that way. Skip anything that fits entirely in the mouth of an adult dog of your breed, and throw out chew toys once they start coming apart.
5. Cleanup — you will need this on day one
An enzymatic cleaner. Not ordinary household cleaner. Enzymatic formulas break down the proteins in urine rather than masking them, which is what stops a puppy returning to the same spot. Regular cleaners leave a scent marker your dog can still smell, even when you can’t. Buy it before the puppy arrives — you will use it in the first 24 hours.

Poop bags. Buy in bulk, keep a roll in every coat pocket and one clipped to the leash. Large dogs produce the volume to match.

Soft training treats. Training starts the day your puppy comes home, and it runs on food. You want something small, soft and quick to eat — a treat that takes thirty seconds to chew kills the rhythm of a training session. Bite-sized puppy treats are made for exactly this.

6. Puppy-proofing the house
Do this before pickup day, not after the first incident.
- Contain the space. A baby gate or exercise pen to limit your puppy to one easily-cleaned room is worth more than any single product on this list. A puppy with access to the whole house is a puppy you can’t supervise.
- Cables and cords. Route them behind furniture or into cable covers. Chewed charging cables are the single most common puppy emergency.
- Check plant names. Several common houseplants — lilies, sago palm, philodendron, pothos — are toxic to dogs. Move them out of reach or out of the room.
- Low cupboards. Cleaning products, medication and food (chocolate, grapes, xylitol) go up high or behind a latch.
- Bin with a lid. Preferably one that locks.
7. The first week: paperwork and vet
- Book a vet appointment for the first few days after pickup, even if the puppy has had their first shots. It establishes a baseline and gets you on the books.
- Get the vaccination record from the breeder or shelter and bring it to that appointment.
- Microchip. If your puppy is already chipped, register the chip in your name — an unregistered chip is useless. If not, arrange it at the first vet visit.
- Pet insurance. Worth pricing in the first month if you’re going to get it: most policies exclude pre-existing conditions, and large breeds are prone to expensive joint problems later.
- Ask about the feeding schedule the puppy is already on, and keep it for the first week.
What you can skip (for now)
Half of a good checklist is what’s not on it. Wait on these:
- An expensive orthopedic bed. Buy it after teething, not before.
- A full grooming kit. A brush suited to your breed’s coat and nail clippers are enough for month one.
- Clothing and costumes. No.
- A retractable leash. Actively unhelpful for a dog that will be strong.
- Bulk food. Buy one bag. You may need to switch formulas, and a 30-pound bag of the wrong food is money gone.
- A second crate for the car. See how often you actually drive with the dog first.
Frequently Asked Questions
How much does it cost to set up for a new puppy?
For a large breed, budget roughly $250–450 for the essentials — the crate is the biggest single line item. You can go lower by choosing a budget crate, and much higher if you buy premium everything.
What should I buy first?
The crate, in the correct adult size. Everything else can be bought in an afternoon; getting the crate wrong costs you the price of a second crate.
Do I need a playpen as well as a crate?
They do different jobs. The crate is for sleeping and short periods of rest; a pen or gated room is for supervised awake time when you can’t watch every second. Most owners of large breeds end up using both.
When can my puppy go for walks?
Usually about a week after the final vaccination round — confirm the date with your vet. Until then, carry them outside or stick to your own garden. You can start collar, harness and leash training indoors right away.
How big will my puppy get?
Ask the breeder about the parents’ adult weights — it’s the best predictor you have, and it’s the number you use to size the crate and harness.
The bottom line
Get six things right before pickup day: a correctly-sized crate, a harness and leash, two stainless bowls, the food your puppy is already eating, a couple of tough chew toys, and enzymatic cleaner. That covers the first week comfortably. Everything else you’ll buy better once you’ve met the dog.
