How many cups of food should I feed my dog based on weight?

As a general guide: 5-lb dogs need 1/2 cup, 10-lb dogs need 3/4-1 cup, 20-lb dogs need 1-1.5 cups, 30-lb dogs need 1.5-2 cups, 50-lb dogs need 2.5-3 cups, 70-lb dogs need 3-3.5 cups, 90-lb dogs need 3.5-4.5 cups, and 100+ lb dogs need 4.5-5+ cups daily. These are approximate amounts for average-calorie kibble (350-400 kcal/cup) split into two meals.

Do puppies need more food than adult dogs?

Puppies need more calories per pound of body weight than adults because they're growing rapidly. A puppy typically needs about twice the calories per pound compared to an adult. However, because puppies are smaller, their total daily amount is less. Feed puppies 3-4 times per day in smaller portions rather than 2 larger adult meals.

How do I know if I'm feeding my dog the right amount?

Monitor body condition rather than relying solely on charts. You should be able to feel your dog's ribs with light pressure but not see them prominently. Your dog should have a visible waist when viewed from above and a tucked abdomen from the side. If ribs are invisible and hard to feel, reduce food by 10%. If ribs are very prominent, increase by 10%.

Dog Feeding Chart by Weight: Complete 2026 Portion Guide

Figuring out how much to feed your dog shouldn't require a math degree, but generic bag recommendations often overshoot actual needs by 20-30%. This comprehensive feeding chart breaks down daily portions by your dog's weight, with separate columns for puppies and adults, so you can find the right amount quickly and confidently.

The chart below is based on standard dry kibble with a calorie density of 350-400 kcal per cup. If your food has significantly more or fewer calories per cup (check the bag's guaranteed analysis), adjust portions proportionally. For the most precise calculation tailored to your specific food, use our Dog Food Calculator.

Complete Dog Feeding Chart by Weight

Dog Weight	Adult Calories/Day	Adult Cups/Day	Puppy Calories/Day	Puppy Cups/Day
5 lbs	200-250	1/2-2/3	300-400	3/4-1
10 lbs	300-400	3/4-1	450-600	1-1.5
20 lbs	500-600	1.25-1.5	700-900	1.75-2.25
30 lbs	650-800	1.5-2	900-1,200	2.25-3
50 lbs	900-1,200	2.25-3	1,300-1,700	3.25-4.25
70 lbs	1,200-1,500	3-3.75	1,600-2,100	4-5.25
90 lbs	1,500-1,900	3.75-4.75	2,000-2,500	5-6.25
100+ lbs	1,700-2,200+	4.25-5.5+	2,200-2,800+	5.5-7+

Puppy columns assume growing puppies (3-12 months) that need approximately 1.5-2x the calories per pound of body weight compared to adults. Giant breed puppies should use controlled-growth formulas with slightly lower calorie targets.

How to Use This Chart

This chart provides starting points. From there, you'll need to refine based on your individual dog:

Find your dog's weight row (use current weight for adults, current weight for puppies)
Start at the middle of the range for the first week
Assess body condition after 2 weeks (can you feel ribs with light pressure?)
Adjust up or down by 10% based on whether your dog is gaining or losing
Re-evaluate monthly as activity levels, seasons, and age change

Factors That Increase Calorie Needs

Your dog may need the higher end of the range (or above it) if they are:

Highly active: Working dogs, sporting breeds, dogs that run/hike daily (+20-40%)
Intact (not spayed/neutered): Hormones increase metabolism (+10-15%)
Young adult (1-3 years): Still developing muscle mass (+10%)
Living in cold climates: Especially outdoor dogs (+10-25%)
Pregnant or nursing: Nursing dogs may need 2-3x normal calories
Underweight: Increase by 20-30% until ideal weight is reached

Factors That Decrease Calorie Needs

Your dog may need the lower end of the range (or below it) if they are:

Low activity: Mainly indoor with short daily walks (-10-20%)
Spayed/neutered: Metabolic rate drops after fixing (-10-20%)
Senior (7+ years): Decreased activity and slower metabolism (-15-25%)
Overweight: Feed for ideal weight, not current weight (-20-30%)
Small breed over 7 years: Often need significantly less than charts suggest
Breeds with efficient metabolisms: Huskies and some other breeds eat less than their size suggests

Understanding Calories Per Cup

Not all dog foods are created equal in terms of calorie density:

Food Type	Typical Calories/Cup	Adjustment Needed
Weight management formulas	250-300 kcal	Feed 15-25% more volume
Standard adult kibble	350-400 kcal	Chart amounts apply directly
High-protein/performance	400-450 kcal	Feed 10-15% less volume
Puppy formulas	380-450 kcal	Adjust based on specific brand
Raw/freeze-dried (rehydrated)	Varies widely	Follow manufacturer's feeding guide

Breed-Specific Considerations

Generic weight-based charts work for most dogs, but certain breeds have unique metabolic characteristics that require adjustment:

Huskies/Northern breeds: Feed 15-25% less than chart suggests due to efficient metabolism. See our Husky feeding guide.
Boxers/Dobermans: May need the higher end due to fast metabolism and lean builds. See our Boxer and Doberman guides.
Bulldogs/Pugs: Feed 10-20% less due to low activity and brachycephalic breathing limitations.
Greyhounds/Whippets: Lean builds need carefully maintained nutrition. Avoid overfeeding despite their size.
Cavalier King Charles Spaniels: Obesity-prone, often need the lower end. See our Cavalier guide.

The Body Condition Score Method

The most reliable way to determine if your portions are correct is the Body Condition Score (BCS), rated on a 1-9 scale:

Score 1-3 (Underweight): Ribs, spine, and hip bones clearly visible. Increase food by 15-25%.
Score 4-5 (Ideal): Ribs easily felt with light pressure but not visible. Waist visible from above. Abdominal tuck from the side.
Score 6-7 (Overweight): Ribs difficult to feel under fat layer. Waist barely visible. Decrease food by 10-20%.
Score 8-9 (Obese): Ribs cannot be felt. No waist. Rounded, barrel-shaped body. Consult your vet for a weight loss plan.

Puppy Feeding Schedule by Age

Puppies need their daily food split into more frequent meals:

6-12 weeks: 4 meals per day (divide daily total by 4)
3-6 months: 3 meals per day
6-12 months: 2-3 meals per day
12+ months: 2 meals per day (adult schedule)

Common Feeding Mistakes

Following bag recommendations blindly: They're often 20-30% higher than actual needs to sell more food.
Not counting treats: Treats should be no more than 10% of daily calories. A single large biscuit can be 100+ calories.
Eyeballing portions: Use a measuring cup or scale every time. Consistency matters.
Feeding for current weight when overweight: Always target ideal body condition.
Not adjusting for life changes: Activity decreases, aging, spaying/neutering all require portion reductions.
