How old is a 2-month-old puppy in human years?

≈ 3 human years.

The standard age to go home: first vaccinations, and the socialisation window is wide open.

Breed size hardly matters yet. A dog's first two years run on the same fast schedule whatever the breed — the first year is worth about 15 human years, the second about nine more. Only after age two do small and giant breeds start to diverge, and then quickly.
