Daily feeding guide

These figures are estimates based on NRC/AAFCO veterinary nutrition formulas. Individual animals vary by up to ±20%. Adjust based on your pet's body condition over 4–6 weeks. Always consult your vet for medical dietary needs.

Dog feeding guides by breed

Choose your breed for a tailored feeding chart. Breed changes metabolic rate — a Border Collie burns more than a Bulldog of the same weight.

How much should you feed?

Dogs are the most over- and under-fed pets in the world — mostly because the guides printed on food bags are population averages that can be 20% off for an individual animal. The right amount depends on your dog's ideal (not current) weight, whether they're neutered, their age, and how active their day really is.

Frequently asked questions

How much should I feed my dog per day?

A 10 kg neutered adult dog at a healthy weight needs roughly 500-560 kcal per day — about 150-165 g of standard dry kibble split over two meals. Scale up or down with weight, activity and life stage using the calculator above.

Should I feed my dog once or twice a day?

Twice a day suits most adult dogs and helps regulate appetite and blood sugar. Puppies need three or more meals; some giant breeds prone to bloat also do better with smaller, more frequent meals.

Is the feeding guide on the dog food bag accurate?

It's a starting point, not a prescription. Bag guides are averages and often run generous. Weigh your dog every few weeks and adjust portions to hold an ideal body condition.

How many calories should a dog eat to lose weight?

Weight loss should target the ideal body weight's resting requirement under veterinary supervision — never crash-diet. The calculator's weight-loss mode estimates a safe reduced target; aim for 1-2% body-weight loss per week.
