Why do dog doses differ from human doses?
Dogs metabolize drugs faster (higher basal metabolism). BSA-based dosing accounts for surface area scaling. Small dogs need proportionally higher doses; large dogs lower.
Should I use weight or BSA for dosing?
Weight-based: simpler, most antibiotics/pain meds. BSA-based: better for chemotherapy, some cardiovascular drugs. Check veterinary reference; most use weight nowadays.
What if I miss a dose?
Give as soon as remembered unless close to next dose (> 2 hrs away). Don't double next dose. Chronic meds (thyroid, pain): missing 1 dose rarely critical. Call vet if unsure.
