Frequently Asked Questions
How much food should I feed my dog per day?
It depends on your dog's weight, life stage, activity, and the calorie density of the food itself. A 20kg active dog eating high-calorie dry food (e.g. 4000 kcal/kg) will need fewer grams than the same dog eating low-calorie food. Use this calculator as a starting point and monitor their body shape.
Should I measure dog food by weight (grams) or cups?
Measuring by weight (grams) is far more accurate. A 'cup' can vary depending on kibble shape, size, and how packed the scoop is. If you use cups, use a standard measuring cup and scoop levelly, or weigh it once to calibrate your scoop.
How many times a day should a dog eat?
For most healthy adult dogs, feeding 2 meals per day (morning and evening) is ideal. Puppies under 6 months usually require 3-4 meals per day to maintain stable energy and blood sugar levels, while senior dogs sometimes benefit from smaller, more frequent meals.
Do I need to adjust the amount if I give treats?
Yes. Treats should never exceed 10% of your dog's daily calorie target. If your dog's calorie budget is 800 kcal, they can have up to 80 kcal of treats, and their main meals must be reduced by 80 kcal to avoid gradual weight gain.
