Canine drug doses are weight-based (mg/kg). Many human medications are toxic to dogs. Always verify dosing with your veterinarian — never extrapolate human doses.
공식
Dose = Dog weight (kg) × Dose per kg; Body surface area (BSA) dose = BSA (m²) × Dose per m²; BSA (m²) = (Weight in g ^ 0.67) / 10,000

자주 묻는 질문
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.
