Dog Food Portion Calculator

Estimate a rough daily food portion for a dog — a general guide, not a substitute for your vet.

Roughly how much to feed

How much to feed a dog depends on its weight, age and activity, and this gives a rough general estimate as a starting point. It is a general guide only, and your vet and the food's own guidance should always take precedence.

A starting point, with important caveats

Feeding the right amount matters for a dog's health, since both under- and over-feeding cause problems, and obesity in particular is common and harmful in dogs. A rough estimate based on weight and activity is a reasonable starting point, but it is genuinely important to understand its limits. Every dog is different — breed, age, whether they are spayed or neutered, activity level, metabolism and health conditions all affect needs, and puppies, pregnant dogs and seniors have particular requirements. Crucially, the feeding guidance on your specific dog food is tailored to that food's calorie content and should be followed, and your vet's advice, based on knowing your actual dog, always takes precedence over any general calculator. The best practical guide is your dog's body condition over time — you should be able to feel the ribs and see a waist — adjusting the amount if they gain or lose weight. Treat this estimate as a rough starting point for a conversation with your vet, not a prescription, and always defer to professional guidance and your dog's food label for feeding your particular dog.
