Why Use a Custom Ratio Calculator?
While the standard 80/10/10 (PMR) ratio is the gold standard for most dogs, every animal is unique. Our Advanced Calculator is designed for owners who need to tweak these ratios for specific needs.
Metric Control
Adjust your dog's maintenance percentage from 1.5% (weight loss) up to 5% (high performance). Ideal for fine-tuning calorie intake without changing the entire diet model.
PMR vs BARF
Instantly switch between Prey Model Raw (No veg) and BARF (Includes veg/fruit/seeds). Or create a custom hybrid model (e.g., 75/10/5/5 + 5% Veg).
Understanding the Nutrient Estimates
This calculator provides estimated daily requirements for key nutrients that are often lacking in raw diets: Zinc, Manganese, Iodine, and Vitamin E. These figures are based on metabolic weight calculations derived from NRC and FEDIAF guidelines.
- Zinc: Crucial for skin and coat health. Often low in modern chicken/beef diets.
- Manganese: Essential for ligament and tendon health. Found in fur, feathers, and blue mussels.
- Iodine: Supports thyroid function. Kelp is the most common whole-food source.
