Raw Dog Food Calculator

--

This is a starting guideline. Adjust based on your dog's individual needs and condition. Split into 2-3 meals for adults, more for puppies.

Using the Raw Dog Food Calculator

This calculator helps estimate the daily amount of raw food for your dog. You'll need to provide:

  • Dog's Current Weight
  • Life Stage
  • Activity Level
  • Body Condition
  • Diet Model: Choose between PMR (Prey Model Raw) or BARF (Biologically Appropriate Raw Food).

The calculator will then suggest a total daily food amount and a component breakdown based on your selected model.

Calculation Method

The calculation is based on a percentage of the dog's body weight, adjusted for life stage, activity, and body condition. The chosen diet model determines the ratio of components.

  1. Base Percentage: Determined by life stage.
  2. Adjustments: Modified by activity and body condition.
  3. Total Daily Amount: Calculated from the adjusted percentage and body weight.
  4. Component Breakdown: The total amount is divided based on the selected diet model's ratios.

Understanding Diet Models

This calculator supports two common raw feeding models:

  • PMR (Prey Model Raw): Aims to mimic the whole prey animal.
    • Typically 80% Muscle Meat
    • 10% Edible Bone
    • 5% Liver
    • 5% Other Secreting Organs
  • BARF (Biologically Appropriate Raw Food): Includes animal products along with plant matter.
    • Typically 70% Muscle Meat
    • 10% Edible Bone
    • 5% Liver
    • 5% Other Secreting Organs
    • 7% Vegetables (e.g., leafy greens, broccoli, carrots - often pureed)
    • 3% Fruit (e.g., berries, apple - seeds removed)
    This model often includes other supplements like oils or kelp, which are not part of this calculator's scope but should be researched by BARF feeders.

Important: These are starting guidelines. Always monitor your dog and adjust amounts as needed. Variety is crucial.

Understanding the Results

The calculator provides:

  • Total Daily Food: In grams and ounces.
  • Component Breakdown: Amounts for muscle meat, edible bone, liver, other organs, and (for BARF) vegetables and fruit.
  • Feeding Percentage Used: The final percentage of body weight.

Transitioning to a raw diet should be done gradually. Consult with a veterinarian or an experienced raw feeding advisor.

Tips for Raw Feeding Success

  • Variety is Key: Aim to feed at least 3-4 different protein sources over time (e.g., chicken, beef, turkey, lamb, fish).
  • Balance Over Time: Don't stress about hitting exact ratios every single meal. Aim for balance over a week or two.
  • Safe Handling: Practice safe food handling for raw meat to prevent cross-contamination. Wash hands, surfaces, and bowls thoroughly.
  • Monitor Stool: Stool consistency is a good indicator of how well your dog is digesting their food. Too much bone can lead to constipation.
  • Consider Supplements (If Needed): Some raw diets may benefit from additions like fish oil (for Omega-3s) or specific supplements, depending on the base ingredients. This is particularly true if not feeding a wide variety or certain components like oily fish. For BARF diets, ensure vegetable and fruit choices are dog-safe.
