How many calories does your pet need a day? Answer a few quick questions to see daily calories, how many can come from treats, an ideal weight and how much water to give.

Tell us about your pet

  1. How much does your dog weigh?

  2. Is your dog neutered or spayed?

  3. Life stage

  4. Activity level

    Be honest. Many indoor pets are less active than we think.

    Couch Companion

  5. Treats per day

  6. Body condition

    Which shape looks most like your pet from above and from the side?

    For the most accurate measurement, gently feel along your dog's ribs and spine to guide your best judgment.

How many calories does my dog need?

A dog's daily calories start from their resting energy needs, which grow with body weight but not in a straight line: a 60 lb dog needs far less than twice what a 30 lb dog does. That base is then scaled up for life stage and activity, and down a little for neutered dogs.

Puppies need the most per pound while they grow. Adults settle into a steady baseline, and seniors usually need less as they slow down.

A 50 lb neutered adult dog with average activity needs about 1,164 kcal a day and around 1,361 ml of water.

Calculate for your dog

How we calculate

We consider your pet’s weight, life stage, activity and body condition to estimate their daily needs—the same approach used in the Every Wag app.

  1. Resting energy

    Start with the calories your pet burns at rest, based on their body weight.

  2. Daily needs

    Adjust for life stage, activity level, and whether your pet is neutered or spayed.

  3. Healthy weight

    Consider body condition to estimate a healthy target weight and the calories needed to support it.

  4. Treats

    Set aside part of the daily calorie allowance for treats, based on how often you give them. The rest comes from food.

  5. Water

    Estimate daily water needs based on body weight, species and activity level.

A starting point for your pet. These are estimates. Every pet is different, so check with your veterinarian before making big changes to your pet's diet, especially if they have a health condition.

Questions pet owners ask

How many calories does my dog need per day?

It depends mostly on weight, life stage, activity and whether they're neutered. As a rough guide, a 50 lb neutered adult dog with average activity needs about 1164 calories a day. Puppies need far more per pound, and seniors and couch-loving dogs need less.

How many calories does my cat need per day?

A 10 lb neutered adult cat with moderate daily play needs roughly 261 calories a day. Kittens need much more per pound, and quieter or senior cats need less.

How many treats can I give each day?

A common guideline is to keep treats to about 10% of daily calories. The calculator splits your pet's total into food calories and treat calories based on how many treats you give, so treats come out of the day's budget instead of being added on top.

How do I know if my pet is overweight?

Run your hands along their sides. You should be able to feel the ribs under a thin layer of fat, see a waist from above, and see the belly tuck up behind the ribs from the side. If you can't feel the ribs when pressing gently, your pet is likely carrying extra weight.

How much water should my dog or cat drink?

Most dogs drink roughly 50 to 70 ml per kg of body weight a day and most cats 40 to 60 ml per kg, with more active pets at the higher end. Wet food counts toward this. A sudden increase in thirst is worth mentioning to your vet.

How much food should I put in the bowl?

Divide your pet's daily food calories by the calories per cup or can on the food label, then split that across meals. The Every Wag app's portion calculator does this for you, in cups, cans or grams per meal.
