Puppy Care Guide

The socialization window: a critical period

The most important developmental window in a puppy's life is the socialization period, which runs roughly from 3 to 14-16 weeks of age. During this window, puppies are naturally primed to approach and investigate new things -- people, animals, sounds, surfaces, environments -- with relatively low fear. Positive, calm exposure to a wide variety of experiences during this period builds a resilient, confident adult dog.

After this window closes, new experiences become harder to process without fear or anxiety, and the adult dog's response to novelty is largely set by what they were and were not exposed to as a puppy. The practical implication is that socialization should start immediately after bringing a puppy home, even before vaccinations are complete -- the American Animal Hospital Association (AAHA) recommends that puppies begin socialization classes as early as 7-8 weeks, within 7 days of their first vaccine, in clean, well-run environments.

What does socialization look like? Calm, positive (treat-rewarded) exposure to: different types of people (men, women, children, people in hats or uniforms), other vaccinated, healthy dogs, a variety of sounds (traffic, appliances, thunder recordings), different surfaces underfoot, car travel, and handling of paws, ears, and mouth. The goal is not excitement but calm, positive association.

House-training basics

House-training requires consistency and patience more than any special technique. The core approach: take the puppy outside (or to the designated toilet spot) at predictable times -- immediately after waking, after every meal, after play sessions, and every 1-2 hours in between for very young puppies -- and give calm, consistent praise and a small treat when they go in the right place.

Young puppies have limited bladder control; a 2-month-old puppy generally cannot hold their bladder for more than 2 hours, and nighttime accidents are expected for weeks. Confinement to a small area or crate when unsupervised is the most effective management strategy, as puppies instinctively avoid soiling their sleeping space. When accidents happen indoors -- and they will -- clean them thoroughly with an enzymatic cleaner (standard household cleaners do not fully neutralise the odour markers that draw puppies back to the same spot).

Punishment after the fact is ineffective and can backfire; puppies do not connect a punishment to something that happened more than a few seconds ago. Catch the puppy in the act, interrupt calmly, and immediately take them outside. The goal is to make getting it right in the right place consistently rewarding, not to make getting it wrong frightening.

Early vet visit timeline

Puppies need a series of veterinary visits in their first months to establish their vaccination and health baseline. A first wellness exam ideally happens within a few days of bringing a puppy home, both to establish care and to catch any issues the breeder or shelter may have missed. Vaccine series typically begin at 6-8 weeks and continue every 2-4 weeks until around 16 weeks of age, following a schedule recommended by your vet.

Core vaccines for dogs -- canine distemper, parvovirus, adenovirus, and rabies -- are recommended by the American Animal Hospital Association (AAHA) for all puppies regardless of lifestyle. Non-core vaccines (bordetella, leptospirosis, Lyme, influenza) may be recommended depending on your puppy's likely exposure. Deworming and flea/tick prevention should also be discussed at these early visits -- intestinal parasites are common in puppies and can be passed to humans.

Spaying or neutering is typically recommended by most vets between 4 and 6 months for most breeds and sizes, though timing recommendations have become more nuanced for large and giant breeds -- your vet will give guidance specific to your puppy's size and sex.

Puppy-proofing your home

Puppies explore the world primarily through their mouths, which means anything at floor level -- or reachable by a determined puppy with any climbing ability -- is a potential hazard. Before bringing a puppy home, get down to their level and assess: electrical cords (chewing is a shock and fire hazard), toxic plants (lilies, sago palm, and many common houseplants are toxic to dogs), human medications left accessible, small objects that could be swallowed, household chemicals, and food items left on low tables.

Many common human foods are dangerous to dogs: chocolate, grapes and raisins, onions, xylitol (found in sugar-free gum and some nut butters), macadamia nuts, and alcohol, among others. Establishing early habits around where food is stored and plates are left will save a great deal of stress as the puppy grows.

A crate or puppy-safe pen is one of the most practical investments for the early months. It is not a punishment tool -- when introduced positively with meals and treats, most puppies readily accept a crate as a safe space. It allows you to give a puppy freedom when you are present and watching, while preventing accidents and hazardous exploration when you are not.

Common mistakes and misconceptions

One of the most common early mistakes is delaying socialization until a puppy is 'fully vaccinated.' By the time a puppy has completed their full vaccine series (typically around 16 weeks), the socialization window is largely closed. AAHA explicitly supports beginning puppy socialization classes before the vaccine series is complete, in clean, well-managed environments, because the behavioural risk of under-socialization outweighs the disease risk in those settings.

Another frequent mistake is using punishment-based training responses to early behaviours like mouthing, jumping, or accidents. Puppies respond much more effectively to consistent positive reinforcement -- rewarding the behaviours you want -- than to corrections that may suppress the behaviour temporarily without teaching the puppy what to do instead.

New owners also frequently underestimate how much sleep puppies need. A young puppy should sleep 16-18 hours a day; insufficient sleep contributes to the 'witching hour' overstimulated biting and chaotic behaviour that many owners find challenging. Enforcing rest periods -- crate time after active play sessions -- is genuinely helpful and not just convenient for the owner.

When to contact your vet

Contact your vet promptly if your puppy: vomits more than once in 24 hours or has persistent diarrhoea (dehydration in puppies can escalate quickly); appears lethargic or uninterested in surroundings for more than a few hours; is not eating for more than 12 hours; has swallowed something potentially toxic or an object; is limping or not using a limb; or has any difficulty breathing. Puppies have less physiological reserve than adult dogs and can deteriorate faster -- err on the side of calling your vet if you are unsure.
