Key Knowledge

What Is the BARF Diet?

BARF (Biologically Appropriate Raw Food) feeds dogs and cats raw muscle meat, bones, and organs β€” replicating the ancestral wild diet. BARF (Biologically Appropriate Raw Food) is a raw feeding model developed by Dr. Ian Billinghurst. It aims to replicate the ancestral diet of dogs and cats: raw muscle meat, raw meaty bones, organ meats, and a small amount of vegetation (for dogs). The core philosophy: feed what a wild canid/felid would eat β€” unprocessed, species-appropriate, and free of grains and fillers.

The 80-10-10 Ratio Explained

Dogs: 80% muscle meat, 10% bone, 5% liver, 5% other organs. Cats: 75% meat, 10% bone, 5% liver, 10% organs. Liver must never exceed 5%. For dogs on BARF: 80% muscle meat, 10% raw meaty bone, 5% liver, 5% other secreting organs (kidney, spleen, pancreas). For cats: 75% muscle meat, 10% bone, 5% liver, 10% other organs (no vegetables needed). The 80-10-10 ratio targets calcium:phosphorus balance (1.2:1 to 1.4:1) and essential micronutrients from organ meats. Liver must not exceed 5% β€” excess vitamin A causes toxicity.

Raw Feeding Safety Guidelines

Raw meat carries Salmonella, E. coli, Campylobacter risks. Freeze 2-3 weeks before feeding, use human-grade sources, sanitize all surfaces. Raw feeding carries pathogen risks β€” Salmonella, E. coli, Campylobacter, and Listeria are found in commercial and homemade raw diets. Safety practices: (1) Freeze meat for 2-3 weeks before feeding to reduce parasite load, (2) Use human-grade meat from trusted sources, (3) Sanitize all surfaces/bowls immediately after feeding, (4) Wash hands thoroughly, (5) Immunocompromised household members should avoid handling raw pet food.

Bone-to-Meat Ratio and Calcium Balance

10% raw meaty bone provides the critical calcium:phosphorus ratio. Never feed cooked bones β€” they splinter. Chicken necks (~40% bone) are a common source. Raw meaty bone provides calcium and phosphorus β€” the most critical mineral balance in a raw diet. Too little bone = calcium deficiency and metabolic bone disease. Too much bone = constipation and mineral imbalance. The 10% bone ratio targets 10-15% of total dietary calcium. Chicken necks (~40% bone), duck necks (~50% bone), and turkey necks (~40% bone) are common BARF bone sources. Never feed cooked bones β€” they splinter.

The Science Behind the BARF Raw Feeding Calculator

Our calculator implements the 80-10-10 BARF model benchmarked against NRC (2006) and FEDIAF nutrient requirements for dogs and cats. Daily food quantity = TargetWeight(kg) Γ— feeding_percentage Γ— 1000g. For dogs: MuscleMeat = total Γ— 0.80, Bone = total Γ— 0.10, Liver = total Γ— 0.05, OtherOrgans = total Γ— 0.05, Vegetables = total Γ— 0.10. For cats: MuscleMeat = total Γ— 0.75, Bone = total Γ— 0.10, Liver = total Γ— 0.05, OtherOrgans = total Γ— 0.10, Vegetables = 0. The feeding percentage typically ranges from 2% (weight maintenance) to 3% (active/working) of body weight. Liver is capped at 5% to prevent hypervitaminosis A.
