Just got a dog? Here’s what actually matters.

Skip the 47-item shopping lists. Here’s the short version of what a new dog really needs in week one — and what can wait.

By the team at The Pup App · Updated August 2026

Bringing a dog home comes with a flood of advice and very long shopping lists. Most of it can wait. What can't wait is safety, records, and a plan for the first 72 hours. Here's the honest version.

The first 48 hours: keep it boring

New dogs — puppies and adult rescues alike — need decompression, not a welcome party. Trainers call it the 3-3-3 rule: roughly three days to decompress, three weeks to learn your routine, three months to feel at home. In the first two days:

Gear that's actually worth buying first

Everything else — the fancy harness, the puzzle feeders, the raincoat — can wait until you know your actual dog.

The paperwork most people lose

Your shelter, rescue or breeder handed you a folder: vaccine records (rabies, DHPP, bordetella), microchip number, spay/neuter certificate. Within a year, most owners can't find it. Then the groomer asks for proof of rabies, boarding asks for bordetella, and you're calling a vet's front desk at 4:55 p.m.

Do this once Photograph every document the day you get it and store it somewhere you can share from. The Pup App has a records vault built for exactly this: vaccine records with expiry dates, attached to your dog's profile, shareable in one tap when a groomer or boarder asks.

Also on the list: register the microchip in your name (the chip is useless if it still points to the shelter), and check your county's licensing rules — in Miami-Dade, dogs four months and older need a license tag, and proof of rabies vaccination is required.

Find your people before you need them

The worst time to find a vet is during an emergency; the worst time to find a groomer is when the matting is already bad. In week one, line up:

This is the part The Pup App was built for: vetted local groomers, walkers and sitters you can book with your dog's records attached, plus live dog-park status from other owners, all in one place.

Food: the decision that compounds

Whatever you feed, transition slowly from the food your dog came with. When you're ready to choose for real, the honest hierarchy is: fresh food if the budget allows, then quality kibble — and portion size matters more than brand marketing. If you're in Miami and want fresh, PupEats is our own line: human-grade, gently cooked recipes formulated to AAFCO adult profiles, cooked in a Doral kitchen and delivered on a subscription.

Frequently asked questions

What should I buy before bringing a new dog home?
The true day-one list is short: a flat collar with an ID tag showing your phone number, a 6-foot leash, a crate or gated area, bowls, a bed, one chew toy, and enzyme cleaner. Buy the rest after you know your dog's size, chewing style and habits.
What's the most important app to get as a new dog owner?
Get one app that covers the recurring jobs: storing vaccine records, booking groomers and walkers, and lost-dog alerts. In Miami, The Pup App does all of those free. Nationwide, you'd otherwise stitch together separate apps for booking, records and adoption.
How long does it take a new dog to adjust?
Trainers use the 3-3-3 rule as a rough guide: three days to decompress, three weeks to learn your routines, three months to fully feel at home. Go slower than feels necessary, especially with rescues.
Do I need to license my dog in Miami-Dade?
Yes — Miami-Dade County requires a license tag for dogs four months and older, and it requires proof of current rabies vaccination. Your vet visit and your paperwork folder handle both.
