Puppy socialisation checklist: what to introduce, week by week

Socialisation means helping your puppy get used to the people, sounds, places, handling and animals it will meet as an adult, while it is young enough to accept new things easily. The PDSA puts this socialisation period at 4 to 12 weeks of age, Dogs Trust describes it as the first four months, and the Royal Kennel Club points to the first 16 weeks. Whichever you go by, your puppy usually arrives part-way through it, so start gently at home on day one, keep every experience short and positive, and carry your puppy in public until your vet says it is protected.

Why the early weeks matter

The Royal Kennel Club says puppies that are well reared and socialised are less likely to react to new experiences fearfully or aggressively. The PDSA warns that under-socialised dogs may develop behaviour problems and phobias later. Socialisation isn't about letting your puppy play with every dog it sees: the Royal Kennel Club defines it as getting used to the world while still listening to you.

The work starts before you collect your puppy. The AKC and the Royal Kennel Club both say breeders should begin with gentle handling and early experiences such as car travel. Ask your breeder or rescue what your puppy has already met, then carry on from there.

A rough week-by-week plan

The PDSA notes that puppies often go home at around 8 weeks. The plan below assumes that; shift it if your puppy arrives later. Your vet's vaccination plan sets the timing for public walks and other dogs, not this table.

The Royal Kennel Club calls weeks 9 to 12 a time for discovering the world "in a safe way", and suggests your puppy meets everything on your checklist at least three times in its first four weeks with you. Repeating things is the point.

The socialisation checklist

Dogs Trust suggests writing your own checklist so nothing is missed. Tick items off as your puppy meets them calmly. These are taken from the PDSA, Dogs Trust, the Royal Kennel Club and the AKC:

• People: adults and children, people of all ages and backgrounds, people with beards, hats, hoods, sunglasses, umbrellas, walking sticks, wheelchairs, rucksacks or high-vis clothing, and visitors ringing the doorbell.
• Sounds: washing machine, vacuum cleaner, hairdryer, traffic. For sounds your puppy is unlikely to hear yet, such as fireworks, the PDSA and Dogs Trust suggest sound recordings played quietly at first.
• Surfaces and places: carpet, tile, wooden floors, linoleum, different outdoor walking surfaces, steps, things to climb over; quiet streets before busy ones (the PDSA suggests a local row of shops before a town centre).
• Objects: bicycles, buggies, suitcases, wheelchairs; a vacuum or hairdryer first switched off, then on (Dogs Trust).
• Handling: picking up, wiping paws, looking in ears and mouth, touching feet and face, nail trims and grooming. The Royal Kennel Club says owners often skip this.
• Car travel: climbing in and out, a safety harness, the engine starting.
• Other animals: cats, and horses or farm animals from a safe distance (Dogs Trust).
• Being alone: a few minutes at first, building up gradually (PDSA).
• Collar and harness: wearing a collar, and trying a harness indoors (PDSA).

Before full vaccination: safe ways to keep going

Vaccinations shouldn't stop socialisation, but they change how you do it. Dogs Trust says puppies shouldn't go out walking in public before they are fully vaccinated, and to ask your vet how long to wait. Until then:

1. Carry your puppy in your arms, a sling or a carrier so it can see and hear the world (Dogs Trust, PDSA).
2. Invite people round to meet your puppy at home or in the garden (Royal Kennel Club). Use your garden only if no unvaccinated dogs use it (PDSA).
3. Choose dogs carefully. Only let your puppy meet friendly, healthy dogs whose vaccination status you are sure about (Royal Kennel Club).
4. Check puppy classes. Ask about vaccination status before you join (PDSA).

Our puppy vaccination guide explains why your vet's dates may differ from other people's, and the 12-week-old puppy schedule shows how short outings fit around naps and meals.

How to do it without overwhelming your puppy

More isn't better. A puppy that is pushed too far learns to be afraid instead.

• Start quiet, then build up. The AKC suggests a few family members first, then one stranger at a time, rather than a party or a busy public place.
• Keep it short and positive. The PDSA recommends short sessions repeated until your puppy is comfortable, with praise and treats for calm behaviour.
• Use distance. The Royal Kennel Club says to keep things at a distance your puppy can cope with and reward it there.
• Keep greetings brief. Ask people to crouch and let your puppy come to them, rather than reaching over it (Royal Kennel Club).
• Spread it out. A few new experiences over several days beats many in one day (PDSA).
• Rest afterwards. Take your puppy home when it seems tired, stressed or over-excited (PDSA).

Signs your puppy is worried

The RSPCA lists these signs of a worried dog:

• low body posture and head, tail tucked under, ears back;
• yawning or licking its lips;
• avoiding eye contact or turning its head away;
• raising a front paw.

Dogs Trust adds moving away and looking worried. If you see these, don't push on and don't coax with treats. Move further away or take your puppy out of the situation, then try again another day from further back (PDSA). The Royal Kennel Club warns that a single bad experience can turn a confident puppy fearful, and that forcing a puppy to face its fears only teaches it to distrust you.

Keep track of what your puppy has met

A checklist only works if you remember what happened. Jot down each new person, sound or place and how your puppy reacted in the DogsLife journal, so you can see what needs another calm repeat. If your puppy stays fearful of something despite slow, positive practice, speak to your vet, breeder or a qualified trainer; the Royal Kennel Club advises asking for help sooner rather than later.
