A Lifespan of About Twenty Years


This is something I will probably incorporate:
Wolves usually live up to 20 years. They live longer in captivity, but rarely past the age of 25.
 And:
Wolves were the most successful mammal until humans came around and took most of their range away.

Which is smarter, a wolf or a dog? Wolves! They are at least 10 times smarter than the domestic dog!

There has never been documentation of a healthy wolf attacking a human.
I had thought to place the age of Ruddy at around 22 or 23. That's long in the tooth, and appropriate for his level of experience.
