Scientific Formula Used
Based on American Veterinary Medical Association recommendations:
First 2 years = 24 human years
Subsequent years vary by size:
- Small: +4.5 years per dog year
- Medium: +5.5 years per dog year
- Large: +6.5 years per dog year
- Giant: +9 years per dog year
Formula:
Human Years = (First 2 years × 12) + ((Current Age - 2) × Multiplier)
Why Breed Size Matters
- Small breeds mature faster but age slower
- Large breeds age rapidly after first few years
- Giant breeds have shortest average lifespan
