Notes & Assumptions
- Formula: RER = 70 × (kg0.75). Daily calories ≈ RER × life‑stage factor × activity factor × goal factor.
- Typical factors: Puppy 0–4 mo ×3.0; Puppy 4–12 mo ×2.0; Adult neutered ×1.6; Adult intact ×1.8; Senior ×1.4 (varies by dog). Activity adds ×0.8 to ×1.6.
- Preset food densities are starting points. Always check your bag/can label for kcal per cup or per 100 g and edit above.
- Every dog is unique. Reassess portions every 1–2 weeks based on body condition and consult your veterinarian for tailored guidance.
