BARF Diet Calculator for Dogs

Calculate the proper portions for a Biologically Appropriate Raw Food (BARF) diet tailored to your dog's specific needs and nutritional requirements.

Dog's Weight (lbs) Enter your dog's current weight in pounds

Dog's Age Enter age in years (puppies: enter decimal, e.g., 0.5 for 6 months)

Activity Level

Life Stage

Body Condition Score: 3 (1-5 scale) 1 = Underweight, 3 = Ideal, 5 = Overweight

Include edible bones in diet

Quick Examples:

How to Use This Calculator

Formula Used

Daily Food Amount (lbs) = (Body Weight × Percentage Based on Life Stage) × Activity Multiplier × Body Condition Factor

Where:

Body Weight = Dog's weight in pounds
Percentage Based on Life Stage = 2-3% for adults, 3-4% for seniors, 5-10% for puppies
Activity Multiplier = 0.8-1.5 based on activity level
Body Condition Factor = 0.8-1.2 based on body condition score

Example Calculation

Real-World Scenario:

Calculating the BARF diet for a 45lb active adult dog with ideal body condition.

Given:

Weight = 45 lbs
Life Stage = Adult (2.5% of body weight)
Activity Level = Active (multiplier of 1.2)
Body Condition = Ideal (factor of 1.0)

Calculation:

Base amount: 45 lbs × 0.025 = 1.125 lbs

With activity multiplier: 1.125 lbs × 1.2 = 1.35 lbs

Result: 1.35 lbs of food daily, consisting of 70% muscle meat, 10% edible bone, 10% organs (half liver), 7% vegetables, and 3% seeds or supplements

Why BARF Diet Matters

Key Considerations

Proper balance of nutrients is essential
Transition gradually from kibble to raw
Source high-quality, human-grade ingredients
Practice safe food handling procedures
Consult with a veterinarian before switching diets

Common Mistakes & Tips

A common mistake is providing too much organ meat, particularly liver. Organs should make up only about 10% of the total diet, with half of that being liver. Too much liver can cause vitamin A toxicity.

If not including edible bones, you must supplement with an appropriate calcium source. The diet should maintain a proper calcium-to-phosphorus ratio of approximately 1.2:1 to support bone health.

Switching too quickly from kibble to raw can cause digestive upset. Transition gradually over 7-10 days, starting with small amounts of raw food mixed with the regular diet, gradually increasing the raw portion.

Frequently Asked Questions

When properly prepared and handled, a raw food diet can be safe for dogs. Practice proper food safety measures including sourcing high-quality ingredients, maintaining clean preparation surfaces, and proper storage. Some dogs with compromised immune systems may not be good candidates for raw diets.

A properly formulated BARF diet typically costs more than commercial kibble. Prices vary based on ingredient quality and sourcing, but generally range from $2-5 per day for small dogs to $5-10+ per day for large dogs. Many owners find the health benefits justify the additional cost.

Dogs are omnivores with carnivorous tendencies, meaning they thrive on animal-based proteins. A vegetarian raw diet is not recommended as it would lack essential nutrients that dogs require from animal sources, including certain amino acids, vitamins, and fatty acids that are difficult to obtain from plant sources alone.
