Basic Puppy Care Checklist — Your First 12 Weeks at Home

Why the First 12 Weeks Are So Important for Your Puppy 

Bringing home a new puppy is an exciting milestone. Full of joy, cuddles, and yes, a few chewed slippers along the way! The first 12 weeks are crucial for learning, bonding, and building habits that last a lifetime. 

From feeding and training to vet visits and bedtime routines, this essential puppy care checklist helps new owners navigate those early weeks with confidence and calm. So your puppy grows happy, healthy, and ready for adventure.

Preparing Your Home for a New Puppy 

Creating a Safe Space for Your Puppy to Settle In

Before your puppy sets paw in your home, create a quiet, cosy space that’s all theirs. Choose a warm corner away from drafts and loud noises, a safe spot where they can relax and feel secure. 

In this area, include: 

• A comfy bed or crate lined with soft blankets 

• Food and water bowls that can’t tip over easily 

• Safe chew toys to help with teething 

• Familiar-smelling items (like a blanket from the breeder) 

This gives your puppy a secure “den” where they can relax, rest, and feel safe. 

Essential Items for Puppies: Your Puppy Starter Checklist

Before your new arrival, make sure you’ve got everything ready: 

• Collar and ID tag (a legal requirement in the UK) 

• Lead and harness 

• Puppy food and healthy treats 

• Food and water bowls 

• Puppy bed or crate 

• Puppy pads (for toilet training) 

• Toys and teething chews 

• Grooming brush and gentle shampoo 

• Waste bags for walks and clean-ups 

Feeding Your Puppy: How to Build Healthy Eating Habits 

How Often Should You Feed Your Puppy? 

Puppies have small stomachs but big energy needs. Their feeding schedule changes as they grow: 

• 8–12 weeks old: 4 small meals a day 

• 3–6 months old: 3 meals a day 

• Over 6 months: 2 meals a day 

Feeding your puppy at consistent times helps regulate their digestion and supports training. 

Choosing the Best Puppy Food for Growth and Health 

Choose a complete and balanced puppy food tailored to their breed size. Puppies need higher levels of protein, vitamins, and minerals to fuel rapid growth and healthy development. 

At Applaws, our natural recipes are crafted to deliver exactly that. Supporting strong bones, healthy teeth, and wagging tails from the very start.

How to Transition Your Puppy to a New Food Safely 

If you’re changing your puppy’s diet, do it slowly to avoid tummy upset. Over 5–7 days, gradually mix more of the new food with their old one. 

Tip: If your puppy has diarrhoea, vomiting, or stops eating, consult your vet before making further changes.

Puppy Health Care: Vet Visits, Vaccinations and Parasite Prevention

Your Puppy’s First Vet Appointment — What to Expect 

Book your puppy’s first vet check-up within the first week of bringing them home. 
Your vet will: 

• Weigh your puppy 

• Check their teeth, ears, eyes, and heart 

• Discuss vaccinations, flea and worming treatments 

• Answer any early-care questions 

Bring any paperwork from your breeder or rescue, including vaccination history and microchip details.

Puppy Vaccinations and When They’re Due 

Core puppy vaccinations protect against: 

• Parvovirus 

• Distemper 

• Infectious hepatitis 

• Leptospirosis 

In the UK, puppies usually receive their first vaccination at 8 weeks, and their second at 12 weeks, with a booster at around 6–12 months. 

Protecting Your Puppy from Fleas, Ticks and Worms

Puppies can pick up parasites easily — even indoors. Start flea, tick, and worm prevention as advised by your vet; most treatments are safe from 8 weeks old. 

Keep a simple diary or set reminders for monthly or quarterly treatments to stay on top of parasite prevention and keep your puppy happy, healthy, and ready for adventure. 

Toilet Training and Sleep Routines for Puppies 

How to Toilet Train Your Puppy Consistently 

Patience and consistency are key! 

• Take your puppy outside first thing in the morning, after meals, and before bed. 

• Praise them immediately when they go in the right spot. 

• Use positive reinforcement — never punishment. 

• Clean up accidents with enzymatic cleaners to remove lingering scents. 

• Setting Up a Bedtime Routine for Your Puppy 

• Sleep routines help puppies feel secure. 

• Offer a final toilet break before bed. 

• Keep the sleeping area quiet and dimly lit. 

• Use a soft blanket or toy for comfort. 

Puppies may whimper the first few nights. Try not to rush in too quickly — they’ll learn to self-soothe and settle.

Socialising Your Puppy During the First 12 Weeks 

Introducing Your Puppy to New People and Other Dogs

Early socialisation helps prevent fear and anxiety later in life. Introduce your puppy to: 

• Family members and visitors 

• Children (supervised interactions) 

• Calm, vaccinated dogs 

• Everyday sounds like hoovers, doorbells, and traffic 

• Safe Socialisation for Puppies Before Full Vaccinations 

Until your puppy’s vaccinations are complete, keep outdoor adventures safe by carrying them in your arms or using a pet carrier. This way, they can explore the world without risk. 

Invite friends with healthy, vaccinated dogs for short, positive indoor playdates — perfect for early socialisation. 

The goal? Show your puppy that the world is a safe, fun place to discover.

Early Puppy Training: Teaching Good Behaviour from the Start 

Reward-Based Training for Puppies

Use praise, play, and small treats to reward good behaviour. Reward-based training helps your puppy learn faster and strengthens your bond. 

Avoid shouting or punishment – it only causes confusion and fear. 

Simple Commands to Teach Your Puppy (“Sit”, “Stay”, “Come”) 

Start with short, fun sessions a few times a day. 

• “Sit” hold a treat above your puppy’s head until they sit. 

• “Stay” reward short pauses before releasing them. 

• “Come” call them in a happy tone and reward when they respond. 

Grooming and Handling Basics for Puppies 

Getting Your Puppy Used to Being Touched and Groomed

Gentle handling now makes vet visits and grooming stress-free later. Touch your puppy’s paws, ears, and mouth for a few seconds, then reward calm behaviour. These small steps build trust and confidence for a lifetime of care. 

How to Introduce Your Puppy to Brushing and Bathing

Start brushing early with a soft brush made for puppies. For bath time, use lukewarm water and a gentle puppy shampoo and always finish with praise to create positive associations. 

Common Puppy Challenges in the First 12 Weeks (and How to Handle Them)

Puppy Biting and Chewing: Why It Happens and How to Stop It

Puppies explore the world with their mouths — especially during teething. Offer safe chew toys and gently redirect biting away from hands or furniture. 

Skip rough play that encourages mouthing; instead, reward calm behaviour to build good habits early.

Managing Separation Anxiety in Young Puppies 

Help your puppy feel confident alone by starting early. Begin with just 5 minutes and gradually increase the time, leaving a favourite toy or blanket for comfort. 

Leave quietly and return calmly. This teaches your puppy that you always come back, building trust and reducing separation anxiety.
