1. What is the OSU Canine Calorie Formula?

The OSU (Ohio State University) formula calculates the Maintenance Energy Requirement (MER) for dogs based on metabolic body weight and activity factors. It's widely used by veterinarians to determine appropriate calorie intake for dogs.

2. How Does the Calculator Work?

The calculator uses the OSU equation:

Where:

• \( weight\_kg \) — Dog's weight in kilograms
• \( osu\_factor \) — Activity/life stage multiplier (see table below)

Common OSU Factors:

• Neutered Adult: 1.0
• Intact Adult: 1.6
• Weight Loss: 0.8
• Weight Gain: 1.2-1.8
• Light Work: 1.2-1.4
• Moderate Work: 1.6-1.8
• Heavy Work: 2.0-5.0
• Puppy: 2.0-3.0

3. Importance of Calorie Calculation

Details: Proper calorie calculation helps maintain optimal weight, prevents obesity-related diseases, and ensures adequate nutrition for working or growing dogs.

4. Using the Calculator

Tips: Enter accurate weight in kilograms and select the appropriate OSU factor based on your dog's life stage and activity level.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert my dog's weight from pounds to kilograms?
A: Divide pounds by 2.205 to get kilograms (e.g., 20 lbs ÷ 2.205 = 9.07 kg).

Q2: What if my dog is overweight?
A: Use the weight loss factor (0.8) and calculate based on ideal weight, not current weight.

Q3: How often should I recalculate my dog's calorie needs?
A: Recalculate after any significant weight change (≥10%) or life stage/activity level change.

Q4: Are there breed-specific considerations?
A: Some breeds may have slightly different metabolic rates. Consult your vet for breed-specific advice.

Q5: Can I use this for puppies?
A: Yes, use the puppy factor (2.0-3.0), but consult your vet as puppies have changing nutritional needs.
