How Much to Feed a Dog by Weight and Age — Complete 2026 Guide

By Marcus J.Vet-reviewed8 min readUpdated May 2026

The most common question new dog owners ask is also one of the most important: how much should I actually feed my dog? Get it wrong and you're looking at an obese dog, a malnourished dog, or a confused pet who never knows when their next meal is.

This guide gives you concrete numbers based on weight and age — not vague "feed as directed" advice.

Note:

Important note

These are general guidelines. The calories in dog food vary significantly by brand. Always check the feeding chart on your specific food's packaging. When in doubt, ask your veterinarian.

Daily Feeding Chart by Weight (Adult Dogs)

This chart is based on standard-calorie dry kibble (approximately 350-400 kcal per cup). Adjust up by 20% for very active dogs, down by 20% for sedentary or overweight dogs.

Puppy Feeding Chart by Age

Puppy eating from bowl

Puppies need more calories per pound than adult dogs because they're growing. They also need more frequent meals to prevent low blood sugar.

Senior Dog Feeding (7+ years)

Senior dogs typically need 20-30% fewer calories than adult dogs at their peak. However, they need more protein to maintain muscle mass.

  • Reduce calories: Switch to a senior formula or reduce portions by 15-20%
  • More frequent, smaller meals: 2-3 meals instead of 1-2 helps digestion
  • Watch for weight loss: Some senior dogs lose appetite — this needs vet attention
  • Joint supplements: Many senior formulas include glucosamine — worth looking for

How to Tell If You're Feeding the Right Amount

!

The rib test

Run your fingers along your dog's ribs. You should feel them easily without pressing hard, but not see them prominently. No ribs + no visible waist = overweight. Visible ribs from a distance = underweight.

Signs your dog is eating too much

  • Weight gain or no visible waist when viewed from above
  • Difficulty breathing or tiring easily
  • Can't feel ribs without pressing firmly
  • Low energy or reluctance to exercise

Signs your dog isn't eating enough

  • Ribs, hip bones, or spine visible from a distance
  • Low energy, dull coat, or excessive shedding
  • Always hungry, begging constantly
  • Weight loss over time

How Often to Feed Your Dog

Adult dogs: Twice daily, roughly 12 hours apart. Morning and evening works well for most households.

Puppies: 3-4 times daily until 6 months, then transition to twice daily.

Senior dogs: 2-3 smaller meals spread through the day aids digestion.

Avoid once-daily feeding for large breeds — it increases the risk of bloat (GDV), a life-threatening condition.

Frequently Asked Questions

How much should I feed my dog per day?
It depends on weight. A 10 lb dog needs about 3/4 cup of dry food daily, while a 70 lb dog needs around 3.5 cups. Always verify with your specific food's packaging since calorie density varies by brand.
How many times a day should I feed my dog?
Adult dogs should eat twice daily, about 12 hours apart. Puppies need 3-4 meals per day. Once-daily feeding is not recommended — it can cause bloat in large breeds and blood sugar problems in small ones.
How do I know if I am feeding my dog enough?
Feel your dog's ribs — you should feel them without pressing hard but not see them prominently. From above, your dog should have a visible waist. If you can't feel ribs and there's no waist, your dog is likely overweight.
Should I feed my dog the same amount every day?
Generally yes, consistency is good for digestion. However, very active days (long hikes, dog sports) may warrant a small increase. Adjust if your dog is gaining or losing weight over time.
