New Puppy Tips: Your First Weeks at Home

Bringing home a new puppy is one of life’s sweetest adventures, and the first few weeks set the tone for everything that follows. Here’s our friendly, practical guide to getting ready, settling in, starting leash and harness training, and planning those very first walks together.

Before your puppy comes home

Puppy-proof your space

Get down to puppy height and look around. Tuck away electrical cords, household cleaners, medications, shoes and anything small enough to swallow. Baby gates or a playpen help you create a safe area for the first weeks.

Your new puppy checklist

• A crate or playpen and a comfy bed
• Food and water bowls
• Puppy food (ask your vet or breeder what your puppy has been eating)
• Chew toys for teething
• Small, soft training treats
• An ID tag with your phone number
• A well-fitted harness and a lightweight leash
• Poop bags and an enzyme cleaner for accidents
• Grooming basics, like a brush and nail clippers

Set up a calm puppy zone

Choose a quiet corner with the bed or crate, water and a few toys. A predictable spot helps your puppy feel secure while everything else is new.

The first day and first night

Keep the first day calm and simple. Let your puppy explore one room at a time, show them where to go potty, and save visits from friends for later.

The first night can be a big change. Many owners place the crate or bed near their own bed so the puppy can hear and smell them. Take your puppy out for a last potty break before bed, and expect a night-time trip or two at first.

Building a first-week routine

Puppies feel safest when their day is predictable. Try to keep meals, potty breaks, play, naps and short training sessions at roughly the same times each day.

Potty breaks

Take your puppy outside often, especially after waking up, after eating or drinking, and after play. Go to the same spot, and praise or reward them right after they go. Accidents happen, so clean them up calmly with an enzyme cleaner.

Naps and downtime

Puppies need lots of sleep. Give them quiet time in their puppy zone between play sessions, especially when they start getting overexcited.

Short training sessions

A few minutes at a time is plenty. Start with their name, “sit” and coming to you, and use treats and praise to reward what you like.

Early socialization: the first 3–4 months matter

From the time they come home until about 3 to 4 months of age, puppies are especially open to new experiences. Gentle, positive exposure during this window helps them grow into confident adult dogs.

• Introduce new people, sounds, surfaces and places in short, happy sessions, with treats.
• Let your puppy watch the world from your arms or a safe spot before meeting it up close.
• Arrange calm meetings with healthy, vaccinated adult dogs you know.
• Go at your puppy’s pace. If they seem worried, add distance and try again another day.

Puppy classes and vaccines

Well-run puppy classes can be a great way to socialize. Veterinary behavior experts support starting some puppies in classes as early as 7 to 8 weeks of age, typically after at least one set of vaccines given at least seven days earlier, plus a first deworming. That isn’t automatic for every puppy, though. Whether and when your puppy can join depends on their health, their vaccination status, the disease risk where you live, and your vet’s advice. Ask your vet when your puppy is ready, and which places are best avoided until their vaccinations are complete.

Leash and harness training your puppy

Leash training can start at home, before your first real walk.

1. Get comfortable with the harness. Let your puppy sniff it, then put it on for a few seconds while giving treats. Build up the time slowly.
2. Add the leash indoors. Clip on a lightweight leash and let your puppy move around with it while you supervise, rewarding calm behavior.
3. Teach “with me.” Walk a few steps inside, say a cue like “Let’s go,” and reward your puppy every few steps for staying near you.
4. Practice outside. Once indoor walking goes well, try a quiet spot outdoors, with tasty treats and few distractions.

Keep sessions short and fun, and stop while your puppy is still enjoying it.

How a puppy harness should fit

Choose the size that fits your puppy’s neck and chest measurements today. A harness should fit securely now, not be bought big to grow into. You should be able to slide two fingers flat under each strap, but that’s only one part of checking the fit: your puppy should move freely, and the harness shouldn’t slip over the head when gently tugged.

Puppies grow quickly, so remeasure regularly, adjust the straps as needed, and move up a size once the current one no longer fits. Our harness fit guide walks you through measuring step by step, and our harness size chart shows which size fits your puppy’s measurements. Our adjustable dog harness comes in XS, S and M/L.

Your puppy’s first walks

When can a puppy go for walks?

Your vet is the best guide. They’ll tell you when your puppy can safely walk in public places, based on their vaccinations. Until then, practice leash skills at home and in your own yard, and keep socializing in safe, controlled ways.

Keep first walks short and sniffy

Puppies have energy in short bursts, so several short outings suit them better than one long walk. Let your puppy sniff and explore at their own pace, and head home before they get tired. Hold off on jogging or long hikes until your vet says your dog’s growth is complete. Our guide to dog exercise has more ideas as your puppy grows.

Watch the weather

On warm days, walk in the cooler morning or evening hours and check the pavement with your palm before you go, as a quick precaution. If it feels too hot to hold your hand there for seven seconds, it’s likely too hot for little paws.

Vet care and nutrition

Book a vet visit soon after your puppy comes home. Your vet will set up a plan for vaccinations, deworming, and flea and tick prevention, and answer your questions about growth, spaying or neutering, and anything else on your mind.

Feed a food made for puppies, and ask your vet which food suits your puppy, how much to feed, and how often.

Common puppy challenges

Teething and chewing

Chewing is normal, especially while puppies are teething. Offer plenty of puppy-safe chew toys, and when your puppy chews something they shouldn’t, calmly swap it for a toy.

House training setbacks

Accidents are part of learning. Go back to more frequent potty breaks, reward success right away, and avoid scolding, which can make puppies nervous about going in front of you.

Getting used to time alone

Start with very short, comfortable separations, even just a few seconds if that’s what your puppy needs, like stepping out of the room and coming right back. Increase the time gradually, only as long as your puppy stays relaxed. If they start to whine, pace or seem distressed, go back to a shorter time. A chew toy or food puzzle in their puppy zone can help your puppy learn that time alone is normal.

New puppy FAQ

Should a puppy wear a harness or a collar?

Many owners use both: a light collar for ID tags, and a harness for the leash, which spreads pressure across the chest and shoulders instead of the neck when a puppy pulls or bounces around.

What size harness does a puppy need?

The size that fits your puppy’s neck and chest measurements right now. Measure with your puppy standing, check the size chart, and remeasure regularly as they grow.

How long should a puppy’s first walk be?

Short. Think a few minutes of sniffing and exploring, not distance. Watch your puppy and head home while they still have energy.

Above all, enjoy these early weeks. They go by fast, and every small moment together builds the bond you’ll share on walks for years to come.
