Veterinary & Livestock Suite
Manage clinical animal dosing, calculate companion pet human-age equivalence, convert traditional equestrian hand measurements, evaluate dry-matter feed allocations, and project livestock hanging carcass cut yields.
Dog Age ↔ Human Age Equivalent
Calculate the human age equivalent of a dog based on their age and breed size category (small, medium, large, or giant), using modern veterinary curves.
Supports decimal years (e.g., 1.5 years for 1 year, 6 months).
Based on AVMA standards: Year 1 is 15, Year 2 is +9, subsequent years add size-dependent values.
Based on standard clinical aging indices for a medium breed dog.
