Germany's hierarchical reverence for seniority may have something to do with the fact that everything here happens relatively late. Germans start school at six, graduate in their late 20s, and get their first proper jobs in their 30s. Adolescence can go on a long time. It is rare for anyone to achieve responsibility before their 50s.
Dogs are a really amazing eye opener for us humans because their lives are compressed into such a short period, so we can see them go from puppyhood to adolescence to strong adulthood and then into their sunset years in 10 to 12 years. It really drives home the point of how finite all our lives are.
There's only one thing harder than living in a home with an adolescent - and that's being an adolescent. The moodiness, the volatility, the wholesale lack of impulse control, all would be close to clinical conditions if they occurred at another point in life. In adolescence, they're just part of the behavioral portfolio.
