How Much Should You Feed Your Dog? A Portion Guide by Weight and Activity
Start With the Label, Then Adjust
Every bag of dog food includes a feeding guide based on your dog's weight. Treat it as a starting point, not a rule. Dogs of the same weight can have very different needs depending on age, breed, activity, spay or neuter status, and metabolism.
Factors That Change Portions
- Age: puppies need more calories per pound, while seniors usually need fewer.
- Activity level: working and sporting dogs burn more energy.
- Neutering: spayed and neutered dogs often need fewer calories.
- Health conditions: some illnesses change nutritional needs.
- Treats: count them as part of the daily total.

Use Body Condition Scoring
You should be able to feel your dog's ribs under a thin layer of fat and see a waistline from above. If ribs are hard to feel, reduce portions slightly. If ribs are very visible, increase them. Weigh your dog every month or two and adjust gradually.
Measure Meals
Use a measuring cup or a kitchen scale instead of guessing. Scoops and bowls vary widely in size, and small differences add up. Feed adult dogs twice a day, and ask your vet for personalized guidance, especially if your dog is overweight or has health problems.
Common Feeding Mistakes
- Free-feeding: makes it hard to track intake.
- Ignoring treats: they add calories quickly.
- Sticking to puppy portions too long: adjust as growth slows.
- Guessing portion sizes: measure meals.
