Why Monitoring Your Dog’s Diet Matters
Dogs, like humans, can suffer from health issues when their caloric intake doesn’t match their energy expenditure. Overfeeding can lead to obesity, diabetes, joint problems, and a shortened lifespan. Underfeeding, on the other hand, may cause lethargy, weakened immunity, or nutrient deficiencies.
With the Dog Diet Calculator, you’re empowered to make data-driven decisions that support your dog’s long-term wellness.

Frequently Asked Questions (FAQs)
1. How accurate is the Dog Diet Calculator?
The calculator uses commonly accepted multipliers based on activity and goals. While accurate for general use, always consult a vet for clinical needs.
2. What is the calorie-per-gram assumption for food?
It uses 3.5 kcal per gram as an average. Always check your specific dog food packaging for precise values.
3. Can I use this tool for puppies?
Yes! Select “High” activity and input their age accurately. Puppies need more energy for growth.
4. Does it account for breed differences?
Not specifically. While some breeds have unique metabolisms, the tool is a good starting point. Adjust based on your dog’s condition.
5. How often should I recalculate my dog’s diet?
Recalculate any time your dog’s weight, age, or activity level changes.
6. What if my dog is overweight?
Select “Lose Weight” as the goal. The tool will reduce calorie recommendations accordingly.
7. What if I feed raw or homemade food?
This tool calculates calories and grams. You can use it as a guideline, but consult a canine nutritionist for raw/home diets.
8. Can I trust this tool over my vet’s advice?
Use it as a supplement to veterinary advice, not a replacement. Vets may use medical data this tool doesn’t access.
