let's stop to think, the most young peoples in Balto movies
has something like 5 or 9, then : to today, anyone who borns
in 1925 has 82 years, so thesekids must have 90 or 100
years, and to who lived in Alaska, most of them are already
no living anymore...
Conclusion: is almost impossible
know anyone who lived in Alaska in Balto times...

I don't know for sure how old are most people in Balto
movies, since they don't mention age in the majority of the
cases (except for Aleu). Anyway, both shebawolf1 and
*ShadowWolf*(AJ) are right; canines aren't surely the
animals that have the longest lifespans (that title either
belongs to some specie of giant shellfish of the Pacific
Ocean, to the giant tortoises of some islands or to the
tuatara of New Zealand).

Shebawolf1 has already answered for the dogs side they live
to 10-15 years so for the wolves side, Wolves in the wild
would normaly live only up to the age of 7 or 8 of years but
it is not uncommon that they have lived longer but the
avarge life spam for a wolf is 7 to 8 years, Depending on the health of the wolf and if it is a area that it would be under threat.

Dogs reach 10-15 is the average age.
as for wolves it
may be considerably shorter due to environmental hazards,
disease injury-and humans
