As soon as you bring your puppy home, it's time to think about training. Puppies are a lot like toddlers — they're still learning about the world, and the foundation you build now shapes the adult dog they'll become.
Beyond basic obedience (which most puppies pick up at puppy school), there are a handful of things you can start doing at home right away.
Quick answer
The single highest-impact thing you can do with a new puppy is socialization — safely exposing them to new people, places, sounds, and surfaces during their critical developmental window (roughly the first 4 months). Alongside this, start desensitizing your puppy early to grooming, vet visits, and being alone, since these are the routines most adult dogs come to dislike if they aren't introduced gently and early.
Why socialization is the most important puppy training step
If there's only one thing you prioritize with your puppy, make it socialization. During this stage, puppies learn the skills that shape their entire adult life:
- Being comfortable and friendly around other people, including children and the elderly
- Learning manners when playing with other dogs and with humans
- Getting used to busy, noisy environments like city streets, cafés, or crowded spaces
The earlier a puppy ventures into the world, the more comfortable they become in it. Puppies kept sheltered from outside experiences — often because owners wait until vaccinations are complete around 4–6 months — can grow into nervous, anxious adult dogs who struggle with busy environments, unfamiliar people, or other dogs.
Key takeaway: Socialization is most critical in the first 4 months of a puppy's life. Quality and safety of exposure matter as much as quantity.
Can I take my puppy for a walk before vaccinations are complete?
Most puppies are still building immunity until their final vaccination round, so your vet will likely advise against walking them on the ground in public spaces. That doesn't mean your puppy needs to stay home, though.
Safe ways to socialize an unvaccinated puppy:
- Carry them in a sling, carrier, or pet backpack when out and about
- Bring them to visit friends or family (as long as their dogs are fully vaccinated)
- Take them along to a midweek lunch or coffee outing
- Sit together on a park bench and let them observe the world from a safe vantage point
The goal during this stage is exposure, not exercise. Aim to introduce your puppy to:
- People of different genders, ages, and ethnicities, including children
- Everyday sounds like traffic, scooters, and bicycles
- Animals such as ducks, horses, or other wildlife
- Everyday obstacles like stairs, elevators, and car rides
- Different textures and surfaces — sand, gravel, wooden boardwalks, metal steps

How do I acclimate my puppy to my lifestyle?
Your puppy should learn to live within your lifestyle, not the other way around. If you regularly host dinner parties, don't put them on hold — let your puppy meet guests and get comfortable with visitors in the home. This helps prevent adult dogs from barking at or feeling anxious around guests later on.
Consider which parts of your lifestyle your puppy will need to adapt to:
- Travel, road trips, or hiking
- Dog-friendly offices
- Working from cafés or co-working spaces
Dogs that aren't exposed to these situations as puppies often struggle to adjust to them later — staying calm during a long car ride or settling in a busy café doesn't come naturally without early exposure.
How do I socialize my puppy with other dogs?
Dog-to-dog socialization is just as important as human socialization. Puppy socialization classes typically accept puppies from 6–8 weeks old, even before vaccinations are finished, allowing them to learn canine social skills from peers.
You can also arrange playdates with friends' dogs, provided they're fully vaccinated and well-mannered. Choose calm, gentle dogs your puppy can safely interact with and learn from.
Note: if your puppy hasn't completed their vaccination course, check with your vet before arranging any dog-to-dog interactions — a healthy, fully vaccinated adult dog is usually a safe option.
Aim for dog-to-dog socialization at least a couple of times per week. Puppies who don't get regular interaction with other dogs are more likely to become reactive, anxious, or aggressive as adults.
Can a puppy be over-socialized?
Socialization isn't just about quantity — quality and safety matter too. Puppies are still developing and can become overstimulated by too much new input, or frightened by an overly rowdy dog.
The good news: puppies tend to bounce back quickly. The key is staying calm and confident when they're startled, rather than reacting anxiously yourself. Much like comforting a toddler who's taken a tumble, a calm, reassuring response teaches your puppy that the world is safe, even when something startles them.
Practical tip: Keep a treat pouch on hand during outings. Offering a treat when your puppy encounters something new — or gets a little spooked — helps build a positive association and shifts their focus in the moment.
How do I get my puppy used to grooming, vet visits, and being alone?
Most adult dogs dislike vet visits, baths, brushing, nail trims, and being left alone — but early, positive exposure as a puppy can prevent this.
Bath time: Start bathing your puppy regularly from a young age. If they're squirmy, smear a small amount of peanut butter on the tub wall to keep them occupied and happy during the bath.
Brushing and nail trims: Build tolerance gradually:
1. Show your puppy the brush or nail trimmer and let them sniff it, then reward with a treat
2. Do a gentle practice stroke or touch (no actual cutting or brushing) and reward again
3. Repeat over a few days until your puppy is relaxed
4. Progress to trimming one small piece of nail, or a few real brush strokes, followed by a treat
5. Build up gradually from there
Alone time: Use a doggy gate or playpen to introduce short, separated periods. Try this after active play, training, or an outing, when your puppy is naturally ready to settle. Start with 20-minute stretches, and offer a long-lasting chew or food puzzle to keep them occupied. Begin by staying in the same room, separated by a gate, before working up to longer or fully separate periods as your puppy matures.
Vet visits: Bring high-value treats (peanut butter, cheese) to every visit, and ask the vet team to hand treats directly to your puppy to build a positive association with the clinic itself.
FAQ
When should I start socializing my puppy? As early as possible — ideally within the first few weeks at home, well before vaccinations are complete, using safe methods like carrying your puppy rather than letting them walk on the ground in public.
Is it safe to socialize my puppy before their vaccinations are finished? Yes, with precautions. Carrying your puppy, avoiding contact with unvaccinated or unknown dogs, and choosing controlled environments (like puppy classes or vaccinated friends' dogs) allow safe socialization during this window. Always check with your vet if you're unsure.
How often should my puppy interact with other dogs? Aim for at least a couple of times a week with calm, well-mannered, vaccinated dogs, or through a puppy socialization class.
What happens if I don't socialize my puppy enough? Puppies with limited early socialization are more likely to grow into anxious, reactive, or fearful adult dogs, particularly around unfamiliar people, dogs, or environments.
How do I stop my puppy from hating baths, brushing, or nail trims? Introduce each activity gradually and pair it with treats and positive reinforcement, starting with simple exposure (sniffing the tool) before progressing to the real activity in small steps.
