How this pet calorie calculator works
We estimate resting energy needs (RER) from body weight, then adjust by life stage, neuter status, activity level, body condition, and your selected goal. This creates a practical starting point for a dog feeding guide or cat feeding guide.
Healthy adult dogs often maintain best around BCS 4-5/9. For best results, track body weight and stool quality, then update portions every few weeks instead of changing food amounts daily.
Frequently asked questions
Is this calculator accurate for every breed?
It is a strong starting estimate. Breed, metabolism, and medical conditions can change requirements, so confirm with your veterinarian for precise feeding plans.
How often should I adjust my pet's calories?
Reassess every 2-4 weeks using weight trend and body condition score. Adjust total calories by about 5-10% at a time.
Can I mix wet and dry food?
Yes. Use calorie values from labels and keep total daily calories consistent. The mixed plan above gives a simple 50/50 calorie split.
