Why Portion Control Matters

Overfeeding is one of the leading causes of obesity in dogs, which can lead to joint problems, diabetes, and reduced lifespan. Underfeeding can result in malnutrition and low energy. Our calculator uses scientifically-backed guidelines from AAFCO and veterinary nutritionists to give you a safe starting point.

Feeding Tips by Life Stage

  • Puppies: Need more calories per pound and more frequent meals (3–4 times daily).
  • Adults: Usually do best with 2 meals per day to maintain steady energy.
  • Seniors: May need fewer calories and smaller portions to prevent weight gain.

Understanding Activity Levels

  • Low: Mostly indoor dogs, short walks. Needs ~20% less food.
  • Moderate: Daily walks and play sessions. This is the baseline.
  • High: Working dogs, agility, or intense exercise. Needs extra fuel.

Always remember: every dog is unique. Use this calculator as a guide and adjust based on your dog's body condition, energy level, and vet recommendations.
