Our calculator relies on recognized feeding models in the raw feeding community, cross-referenced with official nutritional guidelines.
Created by Dr. Ian Billinghurst in 1993 in "Give Your Dog a Bone", BARF (Biologically Appropriate Raw Food) proposes a ratio of 70% meat, 10% bone, 5% liver, 5% organs, 10% vegetables.
Modern BARF community standard, inspired by Dr. Ian Billinghurst's work (1993)
PMR mimics the composition of a whole prey: 80% meat, 10% bone, 5% liver, 5% organs. No vegetables — based on the idea that dogs are strict carnivores.
Prey Model Raw — Based on whole prey proportions
BARF variant with 10% oily fish (sardine, mackerel) for omega-3 fatty acids.
Nordic BARF variation — Omega-3 enriched model
Renal support: Drastically lower heavy proteins (meat) in favor of high-moisture vegetables to relieve kidneys. Bones reduced to 5% and liver to 2% to limit phosphorus. IMPORTANT: This diet is a general guide. Dogs diagnosed with kidney disease must be monitored by a veterinary nutritionist.
Low phosphorus / high moisture clinical model
Hepatic support: Drastic reduction of liver (to limit copper) and increased digestible fibers.
Low copper / modified protein clinical model
The consensus recommends 2 to 3% of adult weight per day, adjusted for activity. For growing puppies, 4 to 8% of current weight is used depending on age.
| Profile | % of weight | Example 20kg |
|---|---|---|
| Sedentary adult | 2% | 400g |
| Normal adult | 2.5% | 500g |
| Active adult | 3% | 600g |
| Puppy 2-4 months | 8% | 1600g |
| Puppy 5-6 months | 6% | 1200g |
| Puppy 7-12 months | 4-5% | 800-1000g |
The ideal calcium:phosphorus ratio is 1.2:1 to 1.4:1. Raw meaty bones (10% of diet) generally ensure this balance. Never add calcium supplements without veterinary advice.
Recommended supplements: fish oil (omega-3), vitamin E (antioxidant), kelp/seaweed (iodine), zinc. Consult your vet for dosages appropriate to your dog's weight.
