How Much to Feed a Dog: A Simple Feeding Guide by Weight and Age

There is no single number that tells you how much to feed a dog. The right amount depends on your dog's weight, age, activity, neuter status and the calorie content of the specific food in the bowl. The best starting point is the feeding guide on the food bag, matched to your dog's ideal weight rather than their current one, then adjusted over a few weeks based on how your dog looks and feels. Most adult dogs do well on two meals a day, and the real goal is not a number on a chart: it is a dog whose ribs you can feel easily and who has a visible waist.

At our clinic in Jbeil, "how much should I give him?" is one of the most common questions we hear. This guide gives you a weight-based starting point, explains how to adjust it, and shows you the thirty-second check that tells you whether you got it right.

Why How Much to Feed a Dog Depends on the Dog (and the Food)

Two dogs of the same weight can need noticeably different amounts of food. A young, intact, active dog burns far more energy than a neutered, middle-aged dog who spends the day on the sofa.

Veterinarians estimate daily calorie needs from the resting energy requirement, or RER: the calories a dog burns at rest, multiplied by a factor for life stage and lifestyle. The Merck Veterinary Manual notes that even then, an individual dog may need as much as 30% more or less than the calculated figure. Every chart is an estimate, and your dog is the final judge.

The food matters as much as the dog, and its quality comes before the calorie count. A portion is only as good as what is in it: a complete and balanced recipe with good-quality protein, from a manufacturer with serious quality control, does far more for your dog than the right number of calories from a poor food. Every product also has a different calorie density, which is why the feeding guide on the bag is the right place to start: the manufacturer has already done the calorie math for that recipe.

Start With the Bag, Then Adjust

Turn the bag over and find the feeding table, which lists daily amounts in grams by body weight. Three rules make it work.

Feed to the ideal weight, not the current weight. If your dog should weigh 20 kg but currently weighs 24 kg, look up the 20 kg line. Feeding the current weight of an overweight dog keeps them overweight. If you are not sure what the ideal weight is, ask us at the next visit.

Treats count. Treats, chews and table scraps all add calories. The usual veterinary guideline is to keep treats at no more than about 10% of daily calories. A few training rewards from our Dog Treats & Chews collection are fine; a steady stream from the dinner table is not.

Adjust gradually. Feed the suggested amount for two to three weeks, then check body condition (explained below). If the waist is disappearing, reduce by a small step; if the ribs are too prominent, increase by a small step.

If you are still choosing a food, our guide to the best dog food covers what to look for on the label before you worry about the portion.

Feeding by Life Stage

Puppy feeding amount

Puppies need far more energy per kilo than adults: roughly three times the resting requirement before four months of age, and about twice from four months until growth is complete. They also have small stomachs, so that energy is spread over several meals.

Feed a food labelled for growth, follow the puppy table on the bag (usually by current weight and age in months), and weigh your puppy regularly, because the right amount changes fast. With large-breed puppies, the goal is steady growth on a large-breed puppy formula, not a puppy that is as round as possible. Our Puppy Food collection has growth formulas for every size.

Adult

Once growth is complete, the job is to keep the weight stable. For a neutered adult, the estimate is about 1.6 times the resting requirement; an intact adult needs a little more, and an obesity-prone dog a little less. Neutering lowers energy needs, so a dog spayed or neutered this year usually needs less food than last year. Browse our Adult Dog Food collection for maintenance formulas by breed size.

Senior

Older dogs are usually less active, so many need fewer calories, while still needing enough good-quality protein to hold on to muscle. A senior dog gaining or losing weight on a steady diet needs a check-up, not just a different scoop. Our Senior Dog Food collection covers this stage.

How Often to Feed a Dog

How often to feed a dog depends mostly on age.

• Puppies: three to four meals a day while they are small, because their stomachs cannot hold a full day's food at once. Most move to two meals as they approach adulthood.
• Adult dogs: two meals a day, morning and evening, is the routine we recommend and the one VCA Animal Hospitals describes as the standard. Some dogs with specific medical conditions do better on three smaller meals; that is a decision to make with your vet.

Scheduled meals beat leaving a full bowl out all day. A dog that grazes tends to eat more than it needs, and when your dog eats at fixed times you notice the first skipped meal immediately, often the earliest sign that something is wrong.

A Starting-Point Dog Feeding Chart by Weight

This dog feeding chart by weight uses the standard veterinary method: resting energy requirement (70 x body weight in kg to the power 0.75), multiplied by a life-stage factor. It gives approximate daily calories, not grams, because grams depend on the food. To turn calories into a portion, find the calorie content on your bag (usually kcal per 100 g) and divide.

Worked example: if your bag says 380 kcal per 100 g and your neutered 10 kg dog needs about 630 kcal, the starting portion is roughly 165 g per day, split into two meals. Compare that with the bag's own table.

Two honest caveats. An intact or very active dog needs more than the neutered column, and a puppy under four months needs more than the puppy column. And the table is a starting point only: individual dogs can land well outside it, and after a few weeks your dog's body condition overrides anything written here or on the bag.

Wet, Dry and Mixed Feeding

Wet food is mostly water, so it carries far fewer calories per gram than kibble. A pouch looks like a lot of food but often replaces only a modest amount of kibble. Follow the feeding table on the wet product just as you would on the dry one.

Many owners ask how much wet dog food to feed when they also give dry. Mixed feeding is a good routine. Two rules keep it healthy:

1. Keep wet and dry as separate meals, never mixed in the same bowl. Kibble has a mechanical teeth-cleaning effect as the dog chews, and coating it in wet food undermines that benefit. Kibble in the morning and wet food in the evening is a simple pattern that works.
2. Keep total daily calories the target. If you add a pouch of wet food, reduce the kibble accordingly. The easiest approach is half the day's calories from each product, each sized with its own feeding guide.

Whichever format you choose, the food must be complete and balanced for your dog's life stage. Our wet dog food and dry dog food collections both deliver across Lebanon.

Reading Your Dog's Body Condition (the Real Test)

Veterinarians score body condition from 1 to 9, with 4 to 5 being ideal. The WSAVA body condition score chart for dogs is the reference we use, and you can do a version of it at home in thirty seconds.

• Ribs: run your fingers along your dog's side. At an ideal weight you feel the ribs easily under a thin layer of fat, without pressing. If you have to push to find them, there is too much cover.
• Waist: look down from above. Behind the ribs, the body should narrow into a waist before the hips.
• Tuck: look from the side. The belly should slope upward from the chest toward the back legs, not hang level.

Signs of overfeeding: ribs hard to feel, waist absent, fat pads at the base of the tail. Signs of underfeeding: ribs and hip bones visible, loss of muscle over the back and hips. Either way, if the picture does not improve after a few weeks of careful adjustment, involve the clinic.

In my experience, we see far more overweight dogs than underweight ones, and most owners are genuinely surprised when a body-condition check at the consult table shows their dog is carrying extra weight. The chart is the start; the dog's body is the answer.

When to Ask a Vet About Portions

Some situations need a tailored plan rather than the bag and the chart:

• Weight gain or loss despite steady feeding, which can point to a medical cause
• A fussy eater, or an appetite that has changed recently
• A diagnosed condition such as kidney, liver or digestive disease, where food and amount are part of the treatment
• Pregnancy, nursing, recovery after surgery or illness, and any dog on a veterinary diet

Questions Pet Owners Always Ask

How much should I feed my dog per day?

Start with the feeding guide on the food bag, using your dog's ideal weight rather than their current weight. As a rough reference, a neutered adult dog needs about 1.6 times its resting energy requirement, roughly 630 kcal per day for a 10 kg dog and 1,060 kcal for a 20 kg dog. Then adjust over a few weeks so that you can feel the ribs easily and see a waist from above.

How many times a day should a dog eat?

Adult dogs do best on two meals a day, morning and evening. Puppies need three to four smaller meals a day until they approach adulthood, because their stomachs are small and their energy needs are high. Scheduled meals are better than a permanently full bowl, for weight control and because a skipped meal is an early warning sign.

How much wet food should I give if I also feed dry?

Decide what share of the day's calories the wet food will provide, for example half, size each product with its own feeding guide, and reduce the kibble by the same share. Serve wet and dry as separate meals rather than mixing them in one bowl, so the kibble keeps its teeth-cleaning effect.

How do I know if I am feeding my dog too much?

Check ribs, waist and tuck. If you have to press to feel the ribs, see no waist from above, or the belly hangs level from the side, your dog is probably getting too many calories. Reduce the daily amount by a small step, cut back on treats, and re-check in a few weeks. If nothing changes, call the clinic.

How much should a puppy eat compared to an adult?

Per kilo of body weight, a puppy eats much more than an adult: roughly three times the resting energy requirement before four months of age and about twice afterwards, against around 1.6 times for a neutered adult. That food should be a growth formula, spread over three to four meals a day, with the portion updated as the puppy grows.
