If treats are included, make sure that the total calories from treats doesn't exceed 10% of your pet's daily calorie intake and then the calculation of Treat and Food Calories will be:
BCS - Body Condition Score
RER - Resting Energy Requirement
MER - Maintenance Energy Requirement
Maintaining a pet’s ideal weight is essential for their overall health and longevity. A pet calorie calculator helps pet owners determine the right amount of daily calories their dog or cat needs based on factors such as weight, activity level, and body condition. Remember: This calculator is a tool for informational purposes only and should not be used as a substitute for professional veterinary advice. Always consult with a veterinarian for personalized recommendations regarding your pet's diet and exercise.
A calorie calculator for pets typically estimates the Resting Energy Requirement (RER) and Total Daily Energy Requirement (DER) using the pet's weight, life stage factors and Body Condition Score (BCS).
The RER is the baseline number of calories an animal needs at rest to maintain vital functions such as breathing and digestion. It is calculated using the following formula:
For Dog: RER (Resting Energy Requirement) = 70 x (body weight in kilograms)^0.75
For Cat: RER (Resting Energy Requirement) = 30 x (body weight in kg) + 70
The DER is the actual number of calories a pet needs per day, depending on their activity level and life stage. It is calculated by multiplying the RER by an appropriate activity factor:
| Pet Type | Condition | Activity Factor |
|---|---|---|
| Dog | Neutered Adult | 1.6 × RER |
| Dog | Active Adult | 1.8–2.5 × RER |
| Dog | Weight Loss | 1.0 × RER |
| Dog | Weight Gain | 1.2–1.5 × RER |
| Dog | Gestation | 1.8–3.0 × RER |
| Dog | Lactation | 3.0–6.0 × RER |
| Dog | Puppy (< 4 months) | 3.0 × RER |
| Dog | Puppy (> 4 months) | 2.0 × RER |
| Cat | Neutered Adult | 1.2–1.4 × RER |
| Cat | Active Adult | 1.4–1.6 × RER |
| Cat | Weight Loss | 0.8 × RER |
| Cat | Weight Gain | 1.2–1.4 × RER |
| Cat | Gestation | 1.6–2.0 × RER |
| Cat | Lactation | 2.0–3.0 × RER |
| Cat | Kitten (< 4 months) | 2.5 × RER |
| Cat | Kitten (> 4 months) | 2.0 × RER |
Prevents Obesity & Underweight Issues – Helps maintain an ideal body condition score.
