Introduction

Raw feeding has gained significant popularity among dog owners, with a 27% increase in Canadian pet parents choosing this diet since 2020. (source) Unlike conventional kibble, raw food requires precise portioning to maintain your dog’s health and prevent nutritional imbalances. Calculating the right amount involves understanding your dog’s unique needs based on weight, age, activity level, and overall health status. This article provides you with the knowledge and tools to determine appropriate raw food portions for your canine companion, including a practical calculator to simplify the process.

Understanding Raw Feeding: The Basics

Raw feeding involves providing dogs with uncooked meats, bones, organs, and sometimes vegetables that mimic their ancestral diet. Two primary approaches exist: the Biologically Appropriate Raw Food (BARF) model, which includes plant matter, and the Prey Model, which focuses exclusively on animal products.

Unlike kibble, raw food cannot be measured in standard cups because the density and weight vary significantly between ingredients. A cup of ground beef differs substantially from a cup of chicken organs in both weight and nutritional content. This variability necessitates measuring raw food by weight rather than volume to ensure your dog receives proper nutrition.

Factors That Affect How Much Raw Food Your Dog Needs

Several key factors determine the appropriate amount of raw food for your dog:

  • Weight and Body Condition: Your dog’s current weight and ideal weight influence portion size. A dog with a body condition score of 4-5 on a 9-point scale (where you can feel but not see ribs) typically requires maintenance feeding, while overweight or underweight dogs need adjusted portions. Properly meeting your dog’s nutritional needs is crucial, and you can read more about creating a nutrient-rich diet here: nutritional needs for dogs in Canada
  • Age and Life Stage: Puppies require more calories per kilogram of body weight than adults, often needing 5-10% of their body weight daily. Senior dogs typically need fewer calories as their metabolism slows.

  • Activity Level: Working dogs, sport competitors, and highly active pets require more calories than sedentary house dogs. A border collie herding sheep all day needs substantially more food than a similar-sized dog that primarily rests indoors.
  • Health Status: Dogs recovering from illness, pregnant or nursing females, and those with certain medical conditions may have specialized dietary requirements that affect portion size.

The Raw Dog Food Calculator

To calculate your dog’s raw food portions, consider these guidelines:

  • For Adult Dogs:
    • Maintenance: 2-3% of ideal body weight daily
    • Weight gain: 3-4% of current body weight daily
    • Weight loss: 1.5-2% of ideal body weight daily
  • For Puppies:
    • 2-3 months: 8-10% of current body weight daily
    • 4-5 months: 6-8% of current body weight daily
    • 6-12 months: 4-6% of current body weight daily, gradually decreasing to adult maintenance levels

Example Calculation:
For a 25 kg adult dog needing maintenance feeding:
25 kg × 2.5% = 0.625 kg (625 g) of raw food daily

For the same dog in pounds:
55 lbs × 2.5% = 1.375 lbs of raw food daily

Raw Feeding Calculation Methods Explained

Two primary methods exist for calculating raw food portions:

  • Percentage of Body Weight Method: This straightforward approach calculates daily food amount as a percentage of the dog’s body weight. Most adult dogs require 2-3% of their ideal body weight in food daily, with adjustments for activity level, age, and metabolism.
  • Caloric Needs Method: This more precise approach calculates the dog’s Daily Energy Requirement (DER) using this formula:
    • Calculate Resting Energy Requirement (RER):
      RER = 70 × (body weight in kg)0.75
    • Multiply by activity factor:
      • Inactive/senior: RER × 1.2
      • Average activity: RER × 1.6
      • High activity: RER × 2.0
      • Working dogs: RER × 2.5+
    • Convert calories to food weight:
      • Raw meat: approximately 1,500 kcal/kg
      • Mixed raw diet: approximately 1,200 kcal/kg

For example, a 25 kg moderately active dog would need:
RER = 70 × (25)0.75 = 70 × 8.98 = 628.6 kcal
DER = 628.6 × 1.6 = 1,005.76 kcal daily
Food amount = 1,005.76 ÷ 1,200 = 0.84 kg (840 g) of raw food daily

Creating Balanced Raw Meals

Proper portioning extends beyond quantity; meal composition matters equally. The widely accepted guideline for balanced raw meals is the 80/10/10 ratio:

  • 80% muscle meat (beef, chicken, turkey, lamb, etc.)
  • 10% organs (5% liver, 5% other secreting organs)
  • 10% edible bone (chicken necks, turkey necks, etc.)

For example, for a dog eating 500 g daily:
• 400 g muscle meat
• 50 g organs (25 g liver, 25 g other organs)
• 50 g edible bone

Rotate protein sources regularly to provide diverse nutrients and prevent intolerances. Include fish occasionally for omega-3 fatty acids, and consider adding small amounts of pureed vegetables if following the BARF model.

How to Adjust Portions Based on Your Dog’s Response

Precise calculation provides only a starting point; observation and adjustment are essential. Monitor your dog’s weight, energy levels, and stool quality weekly for the first month, then monthly thereafter.

Signs of overfeeding include weight gain, loose stools, and lethargy after meals.
Signs of underfeeding include visible weight loss, ribs becoming more prominent, and constant hunger behaviours.

If adjustment is necessary, change portions by approximately 10% at a time. For example, if feeding 500 g daily and your dog is losing weight unintentionally, increase to 550 g daily for two weeks before reassessing.

Create a simple tracking system to monitor:

  • Weekly/monthly weight
  • Body condition score changes
  • Stool quality
  • Energy levels
  • Coat condition

Safety Precautions for Raw Feeding

Raw feeding requires proper food handling to prevent foodborne illness:

  • Thaw frozen raw food in the refrigerator, never at room temperature
  • Store raw pet food separately from human food
  • Clean and disinfect all surfaces, utensils, and bowls after preparation
  • Wash hands thoroughly before and after handling raw meat
  • Discard uneaten food after 30 minutes
  • Consult with a veterinarian or canine nutritionist, especially for puppies, pregnant dogs, or those with health conditions

Conclusion

Calculating the proper amount of raw food for your dog requires understanding their individual needs based on weight, age, activity level, and health status. Begin with the 2-3% of body weight guideline for adult dogs, adjusting as needed based on your dog’s response. Monitor weight and condition regularly, making gradual adjustments to maintain optimal health. While the calculator provides a solid starting point, remember that each dog is unique, and observing your pet’s response to their diet remains the most reliable guide to proper nutrition. For specialized guidance, particularly for dogs with medical conditions, consult a veterinary nutritionist familiar with raw feeding protocols.

FAQ

  • How do I know if my dog is getting enough nutrients on a raw diet?
    Balanced raw meals should follow the 80/10/10 guideline and include a variety of protein sources. Monitor your dog’s coat, energy, weight, and stool quality. For comprehensive nutritional guidance, consult a professional and see these nutritional recommendations.

  • Is raw feeding safe for puppies?
    Yes, if formulated properly to meet all their nutritional needs. Puppies generally need more frequent meals and higher percentages of body weight. For details on puppy raw feeding, check out our puppy nutrition guide.

  • Can I switch my senior dog to a raw diet?
    Many senior dogs thrive on raw, but transition gradually and monitor closely for changes in energy or digestion. Always consult with your veterinarian. See our senior dog food overview for specifics.

  • How often should I adjust my dog’s raw food portions?
    Reassess your dog’s weight, energy, and stool at least monthly. Adjust portions by about 10% if you see significant weight gain or loss.

  • Can raw feeding help with allergies or sensitivities?
    Many owners find a simplified, ingredient-controlled raw diet helps address intolerances. Introduce novel proteins and monitor reactions. When in doubt, seek professional guidance.
