How Dog Age Works
The old "multiply by 7" rule is a myth. Dog aging varies by size:
- Small dogs: Age slower, often live 15-20 years
- Medium dogs: Average aging, live 10-15 years
- Large dogs: Age faster, live 8-12 years
- Giant breeds: Age fastest, live 6-10 years
Dog Life Stages
- Puppy: Birth to 6-12 months (rapid growth)
- Adolescent: 6-18 months (social development)
- Adult: 1-7 years (depending on size)
- Senior: Final third of expected lifespan
