In years (decimals allowed)
The old "multiply by 7" rule is too simplistic. Modern veterinary science shows that pets age differently in different life phases:
Larger dogs generally have shorter lifespans and age faster than smaller dogs. This affects how we calculate their human age equivalent:
Rapid growth and development phase
Active and playful, reaching maturity
Prime years with stable health
Middle-aged with potential health changes
Elderly cat requiring special care
Rapid growth and learning phase
Teenage phase with energy and growth
Prime years with stable health
Older dog needing extra care
Very elderly requiring intensive care
