A working record for the breeder’s weeks of the socialization window — built so that what gets written down is how each puppy responded, not just that it happened.
The most important first
- Keep it per puppy: littermates do not experience the same visitor alike, and the differences are the most useful thing in the record.
- Record a response, not a tick: AAHA warns that exposure without evaluating the response can sensitize rather than desensitize, so a bare “exposed” is worse than no record — it closes a box that may still be open.
- Aim for variety across categories, not repetitions within one: ten kinds of person beats ten visits from one person.
- The completed record goes to the new owner, with a list of what that puppy likes.
How to score each entry
- Date and the puppy’s age
- What it met — “bearded man, deep voice, sat on floor”, not “a man”
- Response, on a consistent scale: approached / hesitated, then approached / watched only / withdrew / startled but recovered / did not recover
- What you changed as a result
If a puppy scores “withdrew” or “did not recover” in more than one category, or keeps scoring that after you have made the exposure easier, do not wait for it to pass. Veterinary guidelines name avoiding unfamiliar people, avoiding friendly animals, fear of many noises with slow recovery, and refusing food or freezing at the vet as signs that development may be off track. Talk to your veterinarian while the puppy is still with you.
People
- Women, men, different ages; children, supervised; teenagers
- Slow-moving people; sticks, frames, a wheelchair
- Beards, glasses, hats, hoods, jackets, uniforms
- Someone noisy; someone who ignores the puppies
- Distinct individuals counted — at least ten, ideally twenty to thirty (EU guidance)
Handling
- Held, turned, lifted
- Paws held, each toe touched, nails clipped; ears looked into, mouth opened
- Brushed, collar worn, weighed, stood on a table
- Held gently on its side, released before it struggles — by you, and by someone else
Surfaces
- Carpet, vinyl, tile, laminate, shiny floor
- Decking, concrete, asphalt, grass, soil, gravel, sand
- Wet ground; a tray of water
- A loose mat or cushion that shifts underfoot
- Metal grid; a low ramp
Sounds
- Vacuum cleaner, washing machine, hairdryer, extractor fan
- Doorbell, telephone, smoke alarm at low volume
- Television, dropped bowls, keys, a slammed door, children shouting, barking dogs
- Thunder, fireworks, sirens — a soundtrack raised in small steps over weeks
- The volume each puppy stayed relaxed at, and where that moved to
Objects and movement
- Umbrellas opening, trash bags, boxes, a tunnel
- Strollers, bicycles, a suitcase on wheels
- Things that move on their own: a ball, a robot vacuum
- One new item every few days, and how long each puppy took to investigate
Environments
- Every room they pass through; dark and echoing spaces
- Their own outdoor area daily, from about five weeks, for at least 30 minutes unless your vet advises otherwise (EU guidance)
- A car: engine off, then running, then a short drive
- A crate or travel box, fed in and left open (see crate and travel)
- From about four weeks: short periods away from the litter with a person who feeds or plays with the puppy, starting at about five minutes and building to ten (EU guidance)
- Later: brief, calm time alone in a safe, familiar space, such as an open crate with a chew, kept short and ended before the puppy becomes distressed
Other animals
- The dam and littermates
- A healthy, well-vaccinated adult dog other than the dam; one of another size
- Cats if relevant; livestock or horses at a distance
- Scent first, sight second, contact third — never an unknown dog
Using it well
Treating a list this long as a scoreboard is the one way to make it harmful: its value lies in the response column. A puppy that watched the vacuum cleaner from across the room and came forward on the third day has been habituated; one that froze each time and was exposed again has been sensitized — and the tick beside its name hides that. Where the response is a withdrawal, the next entry should show something reduced — distance, volume, duration, company — not the same exposure repeated.
Work across the weeks rather than in bursts, within the limits in infection control and biosecurity, and expect the puppies to diverge. Then hand it over: the EU guidance asks that new owners receive the plan showing what the puppy experienced and how it responded, plus a list of what it likes.
Add a small health column next to the log, noting appetite, stool, any cough and energy. These are the weeks when puppies are least protected against infection. A puppy that is off its food, has diarrhea or seems flat should see the vet before any new exposure, not after. When the puppy leaves, highlight any “did not recover” entries for the new owner and suggest they show them to their own veterinarian at the first visit.
Work on it
A few minutes here will teach you more than re-reading the article.
Ask yourself
- Reading back my last litter’s record, could I tell which puppy was most cautious?
- Is there a category I skip because it is inconvenient rather than risky?
Find out & check
- Check which sounds are realistic for the homes your puppies will live in, and find a soundtrack for the rest.
Do one thing
- Print one copy per puppy and write the response scale at the top, so the column cannot be left blank.
