Frequently Asked Questions

Is the 1 dog year equals 7 human years rule accurate?
No, the 1:7 rule is scientifically outdated. Dogs mature rapidly during their first two years (approx. 15 human years in year one). Furthermore, large breeds age biologically faster than smaller breeds.
How does dog size affect biological age?
Small breeds (under 10 kg) frequently live 14-16 years, whereas large breeds (25+ kg) reach senior status around age 7-8. Aging multipliers are therefore adjusted by size tier.

How Is Dog Age Calculated?

Dog age is no longer treated as a simple β€œ1 dog year = 7 human years” rule. Small breeds often age more slowly, while large breeds mature and age faster, so body size is a better reference.
