Adult dog standard is 2 meals (morning & evening)

Calculation Steps

• RER = 70 × 8^0.75 = 333 kcal
• 계수 1.60 (개·adult·medium·ideal)
• MER = RER × 계수 = 533 kcal/일
• 사료 380 kcal/100g 기준 → 하루 약 140g (2회 배급 시 1회 70g)

Feeding Tips

• Feed 2–3 times per day (especially for small or young pets).
• Limit treats to 10% of MER to prevent nutritional imbalance.
• Check weight every 2 weeks and adjust ±10% as needed.
• Always provide fresh water.
