Choose Dog or Cat, and pick your dog's breed weight category (Small, Medium, Large, Giant).
Input pet age in calendar years and optional extra months.
Inspect human equivalent age, life stage category (Puppy, Prime Adult, Senior), and care milestones.
No. Modern veterinary science demonstrates that dogs age much faster during their first 2 years (reaching biological adulthood ~24 human years), after which smaller breeds age slower than giant breeds.
A 1-year-old cat equals approximately 15 human years, a 2-year-old equals ~24 human years, and each subsequent feline year adds approximately 4 human years.
