@loveisrael There's piles of ideas if you Google "puppy socialisation checklist" or "puppy socialisation passport". I think these are good for inspiration, but also sort of miss the point.
There isn't one magic list of things that your puppy should see by X age in order to become a happy, confident adult dog. And you don't have to do everything. Your puppy doesn't
need to see a tall black man with a limp carrying an umbrella in order to be confident around tall black men with limps carrying umbrellas later in life.
Socialisation is about three things:
- Teaching the pup how to behave around things that will be a regular part of his life. For me sheep and horse riders are on that list, whereas busy roads and close encounters with young kids are not. If you have kids or live in the city your list will be different to mine. Technically this is not purely about socialisation, it is also about rewarding the right behaviour - but starting as soon as possible makes the training easier.
- Experiencing a wide variety of new things with all senses - sight, sound, smell, walking on different surfaces, going on car rides, seeing what the world's like after dark etc.
- ALSO (and more importantly IMO) building an optimistic outlook towards novelty. This means that the experiences the puppy has with these new things need to be overwhelmingly positive or neutral. Once the puppy has built up this optimism he will be quite resilient to new things that he encounters, even if he never saw them as a pup.
Let the puppy engage with things in his own time. If he seems nervous, move further away or pick him up so he feels safer, and wait. Socialisation shouldn't mean being forced to interact with people or things if the pup doesn't want that. If your pup wants to interact and it's appropriate, by all means let him - but it's far better to spend 20-30 minutes just watching the world go by, than to have 20-30 people pat your pup in one morning down at the farmer's market.
While socialisation needs to be a major focus during the early months (up to 14-16 weeks depending on which source you look at), it's also important that the puppy regularly sees new things throughout his first year. My goal with a pup is that he has one new experience every day until 16 weeks, and then one new experience every week up to 12 months. I don't achieve that (nobody's perfect) but every happy/neutral experience increases the odds that I will have a confident older dog.
