This tool is especially helpful for:
- New dog owners
- People managing a dog’s weight
- Transitioning from puppy to adult diets

🧪 Practical Example: How Much Should You Feed a 50 lb Active Dog?
Let’s say your dog weighs 50 lbs and is highly active.
- First, convert 50 lbs to kilograms:
50 × 0.453592 = 22.68 kg - Multiply by the high activity factor (0.04):
22.68 × 0.04 = 0.9072 kg of food/day - Convert to grams:
0.9072 × 1000 = 907 grams/day
Result: You should feed your 50 lb active dog approximately 907 grams of food per day.
🐕 Why Getting the Right Portion Size Matters
Feeding your dog the proper amount isn’t just about keeping them full — it’s about supporting their:
- Weight management
- Digestive health
- Muscle maintenance
- Energy levels
- Lifespan and quality of life
Overfeeding can lead to obesity, joint problems, and metabolic issues. Underfeeding can result in nutrient deficiencies, fatigue, and weakened immunity. This calculator empowers you to get it right every time.
