How Much Should I Feed My Dog?

There is no single right number. Start with the feeding chart on your dog's food, based on their ideal weight, split it into measured meals, then adjust to your dog's body condition. If your dog's ribs are easy to feel but not see and they have a visible waist, the amount is about right.

Every dog is different. A couch-loving senior and a young herding dog of the same weight can need very different amounts, which is why the label is a start and not a final answer.

Start with the food label

Check the feeding chart on the package. It lists a daily amount, usually in cups, for a range of body weights. Use your dog's ideal weight, not necessarily their current weight. An overweight dog should be fed for the weight they should be, and a thin dog for the weight they are working toward. If you are not sure what that is, your vet can tell you.

Foods differ a great deal in calories per cup, so a cup of one food is not the same as a cup of another. When you change foods, read the new label instead of reusing the old scoop count.

Our dog food calculator gives a rough daily estimate to compare with the bag.

What changes how much your dog needs

Several factors move the number up or down:

Age. Puppies need extra calories and nutrients for growth, and older dogs' needs often change too. See our puppy feeding schedule for growing dogs.
Size. Larger dogs eat more overall.
Activity. Dogs who run, work or play hard burn more.
Spayed or neutered status. Spayed and neutered dogs need fewer calories than intact dogs.
Pregnancy or nursing. These dogs need more.
The food itself. A calorie-dense food goes further, so you feed less of it.

Calculators and charts, including the calorie ranges the WSAVA publishes for healthy adult dogs, are best treated as starting points. PetMD notes that individual dogs can need as much as 50 percent more or less than the average.

Check your dog's body condition

Your dog's body shows whether the amount is right. Vets use a nine-point body condition score, where 4 or 5 is ideal. At that range:

You can feel the ribs under a thin covering of fat but not see them
Your dog has a visible waist when you look from above
The belly tucks up when you look from the side

Cornell estimates that each point away from ideal is roughly 10 percent of body weight. A dog at 7 out of 9 is carrying about 20 percent extra. Our guide on how to tell if your dog is overweight walks you through a hands-on check.

Measure meals instead of guessing

Eyeballing a scoop adds up fast. Cornell warns that heaping portions can easily add extra calories. Use a proper measuring cup (1 cup is 240 ml) to check each portion, as AAHA advises, or a kitchen scale. VCA points out that cups are not precise, even when the same person feeds every time, and recommends weighing food with a digital kitchen scale for large and giant breeds.

Keep using the same food, and write down the amount you settle on. If you want to switch, mix the new food in gradually over about a week to 10 days.

How many meals a day

PetMD suggests two meals a day for small and medium adult dogs, and two to three meals for large and giant dogs. VCA goes a step further for big dogs, recommending at least three smaller meals a day because feeding one large meal is linked to a higher risk of bloat. Scheduled meals beat leaving food out all day, which makes it harder to control calories and to notice when your dog stops eating well.

If your dog gulps their food, a slow-feeder bowl can help them take it more slowly. VCA lists eating very quickly as another bloat risk factor.

Count the treats

Treats should make up no more than about 10 percent of your dog's daily calories. When you give a lot of treats, reduce the meal portion to keep the total balanced. Tiny, soft treats, pieces of the regular kibble and small vegetable bites go further than big biscuits. Cornell mentions peas as one option.

Adjust over time

Weigh your dog regularly, at home on a scale or at the vet, and keep a log. If your dog gains weight, trim the daily amount slightly. If they slim down too much, increase it, and ask your vet if the change seems unexplained. Reassess a few weeks after any change.

Food is only half of the picture. Gentle exercise such as walking supports a healthy weight, though it works best together with sensible portions. A dog who has been inactive should build up activity gradually to avoid injury. Our exercise guide can help you plan it, and Cornell recommends weighing a dog on a weight-loss plan at least every two weeks.

When to call your vet

Talk to your vet if:

Your dog is overweight or underweight and you are unsure how much to feed. Do not simply cut back a normal diet on your own, since that can lead to nutrient shortfalls. Your vet can set a target weight and a plan, and weight loss is usually kept to a gradual 1 to 2 percent of body weight a week.
Your dog's appetite or weight changes suddenly without a clear reason.
You have a puppy, a senior or a dog with a health condition, such as kidney disease or diabetes, whose needs differ from average.
You want to switch to a homemade, raw or prescription diet.

Extra weight raises the risk of problems such as arthritis. See our page on obesity in dogs for more.

Frequently asked questions

How many times a day should I feed my adult dog?

Two meals a day suits most adult dogs. For large and giant breeds, PetMD suggests two to three meals and VCA at least three smaller meals, partly to lower the risk of bloat, so ask your vet what is best for yours.

Are the amounts on the dog food bag accurate?

They are a starting point. Charts are written for an average dog, and individual needs can be as much as 50 percent higher or lower. Use body condition and your vet's advice to fine-tune.

How many treats can my dog have?

Keep treats to about 10 percent of daily calories, and trim the meal portion to make up for them. Small, low-calorie options can stretch further than big biscuits.

Should I leave food out all day?

Scheduled, measured meals are better for most dogs. They make it easier to control calories and to notice when your dog's appetite changes.
