When can a puppy meet the world? Build a socialisation checklist

Your puppy's brain is most open to new things in the first few months, so what it meets calmly now tends to feel normal later. But vaccinations mean some places are off limits for a while.

Build a checklist of 20 everyday experiences, tick them off as your puppy meets them calmly, and see how much of the early window is left. Always ask your vet what is safe for your puppy.
