Bringing home a new puppy is one of the loveliest things you'll ever do, and one of the most bewildering. The first six months pass in a blur, and a great deal happens in them.
In your puppy's first six months, you'll choose your pup and bring them home (ideally before eight weeks old), help them through a wobbly first night, and build a steady daily routine. You'll make the most of the all-important socialisation window that starts closing at around 14 weeks, settle them onto a complete puppy food, and begin gentle exercise and reward-based training. You'll keep on top of vaccinations and worming, and then ride out the "teenage" phase that tends to arrive between four and six months. Do those things calmly and consistently, and you give your dog the best possible start towards a happy, confident adulthood.
With roughly 10.6 million pet dogs now living in the UK (PDSA, 2024), you're in good company. Here's how to make those first six months count.
What to expect month by month
Every puppy is different, but most follow a broadly similar path:
-
Weeks 8 to 9: Homecoming, first nights, and learning where the toilet, bed, and bowls are.
-
Weeks 9 to 12: Routine takes shape, house training gets going, and early socialisation begins safely, before full vaccination.
-
Weeks 12 to 16: Second vaccinations done, first proper walks, and the socialisation window starts to close.
-
Months 4 to 6: Teething, fast growth, and the first signs of adolescent behaviour as hormones kick in.
Keep that map in your head and the rest of this guide will slot into place.
Timing it right: winter puppy or summer puppy
The season you bring a puppy home can shape their early experiences, with pros and cons on both sides.
Winter and autumn puppies often grow up more comfortable being handled, towelled off and bathed, simply because the weather makes all of that necessary, and they tend to take rain and darkness in their stride. The catch is that shorter, colder days make those endless toilet trips harder work, with fewer people and dogs about to help with socialising.
Summer puppies get longer days for garden toilet trips and far more going on outside to see and hear, which is wonderful for socialisation. The trade-off is that warm weather means less need for towelling, so you'll have to create those experiences on purpose. Summer pups also tend to hit adolescence as the nights draw in, which can collide with fireworks season.
There's no right answer, just things to weigh up and plan around. We've written a whole piece on choosing a winter or summer puppy if you'd like to dig deeper.
Choosing your puppy from the litter
To make the most of the socialisation that puppyhood allows, it's best to bring your puppy home before they're eight weeks old. You can usually visit once the litter is at least four weeks old, and taking a calm friend along helps you see clearly when your heart is melting.
When you visit, watch how the puppies behave with one another and with you:
-
A well-rounded pup is usually curious and confident, holding its head high and wagging its tail, without being pushy or domineering.
-
Notice how they react to being gently handled and picked up, especially if you have children at home.
-
Look for calmness and friendliness rather than fearfulness, which can be hard to change even at a young age.
-
Check the living area. Pups routinely soiling their bedding may carry that habit home.
On the health side, look for a shiny coat, bright eyes, and clean ears with no discharge. Your pup should be in good condition, neither pot-bellied nor skinny. You don't have to decide on the spot, and a check-up with your own vet before you commit can put your mind at ease. There's more in our guide to selecting a puppy from the litter.
Getting your home ready
A little prep now goes a long way later. Start by puppy‑proofing your home: tuck cables out of sight and move anything chewable or harmful well out of reach. Puppies don’t stay small for long, so what’s safe today might not be tomorrow. Best to stay one step ahead.
Next, set up their spaces. Give your puppy a quiet, draught-free spot to rest, ideally a crate or cosy bed, and keep food and water bowls separate from where they sleep. Check the garden over too, with no gaps to squeeze through or dig under.
Your shopping list doesn't need to be enormous. But costs add up, so it helps to plan ahead.
The basics include:
-
A crate and a comfy bed with plenty of bedding
-
Food and water bowls
-
A complete puppy food (more on choosing one below)
-
A collar and ID tag (a legal requirement in the UK), plus a lead and harness
-
A car restraint or carrier for safe travel
-
Toys, including something safe to chew
-
Poo bags and puppy toilet-training pads
The journey home
The first car journey matters more than people realise, because it's your puppy's first taste of the world without their mum and littermates.
Never let your puppy travel loose. For short trips, having one person gently hold them while someone else drives is a lovely way to start building that early bond. For longer journeys, a secure carrier with a blanket that smells like their mother can make all the difference. However you travel, it’s important your pup is safely restrained. It keeps them comfortable and secure, and means everyone can relax and enjoy the ride.
Some puppies feel queasy at first, much as we can, so pack paper towels and a bag or two, and plan regular comfort stops. Little bladders can't wait long, and a whine usually means it's time to pull over.
The first night
Ah, the first night. Your puppy has just left everything they've ever known, so a few tears, theirs and possibly yours, are completely normal.
Keep their first evening calm and let them explore one or two rooms at their own pace. Show them where their toilet spot, water and bed are. At bedtime, settling them in a crate near you gives them a safe, cosy space of their own without the run of the house. A warm (not hot) covered hot water bottle tucked into their bedding can mimic the warmth of snuggling up to littermates, making those first nights a little easier.
Set an alarm to take them out to their toilet spot every few hours, since young puppies can't hold on through the night yet. If they whimper, try not to rush back every time to fuss over them, or they'll quickly learn that crying brings company. It's a fine balance between reassurance and quietly building independence, and it does get easier within a week or two.
Weeks one to four: settling in and routine
Once the dust settles, your job is to build a gentle, predictable rhythm. Puppies feel safest when they know what's coming, so keep mealtimes, naps, play and toilet trips at roughly the same points each day.
House training starts now, and patience is everything. Take your puppy out first thing, after meals, after naps and after play, and reward them warmly the moment they go in the right place. Never tell them off for accidents indoors, which only teaches them to hide away and go to thetoilet. Some pups get the hang of it in a few weeks, others take months, and both are normal.
Now is also the time to introduce very short spells alone, building up slowly from a minute or two, so being by themselves becomes no big deal. Done gently and early, this can help head off separation-related behaviour later. Sleep matters enormously too, so resist the urge to keep playing with a tired pup and give them space to switch off.
The socialisation window, and what to do before vaccinations
Here's something many owners don't realise until it's too late: the window for socialisation closes sooner than you'd think.
Puppies have a sensitive period that runs from around three weeks to roughly 14 weeks of age, during which they're naturally curious and open to new experiences (McEvoy et al., 2022). Positive experiences now help shape a confident adult dog, while a pup who misses out can grow up more fearful and find new things harder to cope with later.
The tricky part is that this window overlaps with the period before your puppy is fully vaccinated. The answer isn't to keep them shut away, but to socialise safely:
-
Carry your puppy out and about so they take in traffic, crowds and noise from the safety of your arms.
-
Invite calm, fully vaccinated friends' dogs and gentle visitors to your home.
-
Introduce everyday sounds gradually, from the hoover and hairdryer to the doorbell.
-
Get them used to gentle handling of ears, paws and mouth, so vet visits and grooming feel ordinary.
Short, positive, and frequent beats long and overwhelming every time.
Feeding your puppy
Good nutrition is at the heart of those early months. Your puppy is growing fast, so giving them the right nourishment now helps set them up for a healthy, happy life.
Choose a complete puppy food, meaning one formulated to provide everything a growing dog needs in the right balance. When you first bring your puppy home, keep feeding whatever the breeder used for the first week, then switch gradually over several days to a week to avoid upsetting their tummy. A sudden change of food is a common cause of an unsettled stomach in a new pup.
Our puppy recipes are made with freshly prepared meat and fish ingredients as the number-one ingredient, with no artificial colours or flavours, and no wheat, soya or dairy. Many owners like to combine wet and dry food, known as mixed feeding, which can make mealtimes more interesting and help with hydration. Our wet puppy food comes in trays that pair easily with a dry recipe.
A few feeding principles worth holding onto:
-
Weigh portions with kitchen scales rather than a scoop or cup. Food density can vary from batch to batch, so weighing in grams is far more accurate.
-
Use the pack guidance as a starting point, then adjust to your individual pup. Activity, breed and growth rate all play a part, so there's no single right amount we can give.
-
Feed little and often, reducing the number of meals as your puppy grows.
-
Check in with your vet if you're ever unsure whether your puppy is the right weight or growing as they should.
Exercise, play, and early training
Puppies are bundles of energy, but their growing bodies need protecting, so the type and amount of exercise matters.
A widely used rule of thumb from The Royal Kennel Club suggests around five minutes of formal, lead-based walking per month of age, up to twice a day, until your puppy is fully grown. So a four-month-old might manage two 20-minute walks. It's a guideline rather than a hard rule, and the exact numbers are still debated (Veterinary Practice), but the idea behind it is simple. Your puppy’s joints and bones are still developing, so it pays not to overdo structured, repetitive exercise. Gentle play and a bit of pottering around the garden are different, though, and just what they need at this stage.
Mental exercise can tire a puppy out just as much too. Short, fun, reward-based sessions are perfect for teaching the basics — their name, "sit" and coming when called — while strengthening your bond along the way. Keep it light, keep it positive, and reward the behaviours you’d love to see more of. A few well-timed natural dog treats make handy training rewards. Always use kind, positive methods rather than punishment, which damages trust and tends to backfire.
Health: vaccinations, worming, and the neutering conversation
Your puppy's first vet visit is a good moment to get everything in order and to build a relationship with a practice you trust.
In the UK, puppies usually have their first vaccination at around six to eight weeks, followed by a second two to four weeks later, typically at 10 to 12 weeks (RSPCA). Most can head out for their first walk on the ground about one to two weeks after that second jab, though your vet will confirm the right timings. While you're there, ask about routine worming and flea treatment, and note when boosters are due.
Neutering is worth thinking about too, but there's no need to rush into it. The right timing depends on your dog’s breed, size and sex, so it's a conversation to have with your vet rather than a one-size-fits-all answer. Keep your puppy's microchip details up to date as well, which is a legal requirement for dogs in the UK.
Somewhere between three and six months, your puppy will start teething, losing their baby teeth and growing 42 adult ones (Petplan). Expect plenty of chewing, and offer safe, appropriate chews to give sore gums some relief, which saves your furniture in the process.
Months four to six: the teenage phase
Just when you think you’ve cracked it, many owners find their sweet little puppy has other ideas and turns into a bit of a hooligan. Welcome to adolescence.
From around four months, hormones begin to surge. In males, testosterone rises and tends to peak at about 10 months before settling. In females, rising oestrogen can make some pups seem more irritable or unsettled. The result is often a dog with more energy, bolder behaviour, a shorter attention span, and a sudden talent for ignoring cues they knew perfectly well last week.
This isn't your imagination, and it isn't bad training. Research from the UK has shown that dogs going through puberty, at around eight months, become temporarily less responsive to commands from their own caregiver, much like human teenagers (Asher et al., 2020). The same research notes that adolescence is the stage when dogs are most likely to be given up to rehoming centres, which tells you just how testing this phase can feel. Knowing it's coming, and that it passes, makes all the difference.
A few things help you both through it:
-
Keep up the exercise and enrichment. A tired, mentally satisfied teenager is a calmer one.
-
Stay consistent with training. Responses may get sloppy, but keep gently reinforcing the basics rather than giving up.
-
Reward calm behaviour whenever your dog gets it right.
-
Lean on good role models. Time around a calm, well-mannered adult dog can teach your youngster more than you'd expect.
-
Don't stop socialising. Adolescent dogs can seem wary of things they took in their stride a few weeks earlier, so keep up safe, positive outings.
Hang in there. With patience and consistency, your hormone-fuelled adolescent will settle into the calm, characterful adult dog you've been working towards.
A calm, consistent start is everything
The first six months ask a lot of you, and there will be days you wonder what you've taken on. That's normal, and the hard parts are phases, not forever. Keep things calm, kind and consistent, feed your puppy well, make the most of that early socialisation window, and ride out the teenage wobble with patience. Get those foundations right, and you'll have given your dog a wonderful start, and yourself a friend for life. If a worry ever niggles at you, a quick chat with your vet can help put your mind at ease.
