The Short Answer
The amount to feed your dog depends on their weight, age, activity level, and the calorie density of their food. A 50-lb active adult dog needs roughly 1,000–1,200 calories per day, which translates to about 2.5–3 cups of standard dry food.
But every dog food has different calorie content. A premium kibble might have 450 cal/cup while a budget brand has 320. Always check the label and adjust accordingly.

| 30 lbs | 650–800 cal | ~1.75 cups |
| 50 lbs | 900–1,100 cal | ~2.5 cups |
| 70 lbs | 1,100–1,400 cal | ~3 cups |
| 90 lbs | 1,400–1,700 cal | ~3.75 cups |
Puppy Feeding Schedule
Puppies need more calories per pound than adult dogs because they're growing rapidly. They also need to eat more frequently because their stomachs are small.
- 6–12 weeks: 4 meals per day
- 3–6 months: 3 meals per day
- 6–12 months: 2 meals per day
- 12+ months: 2 meals per day (adult schedule)
Feed puppy-specific food until your dog reaches adult size. Small breeds reach adult size around 10–12 months. Large and giant breeds may not be fully grown until 18–24 months.
Senior Dogs
Dogs over 7 years typically need 20–30% fewer calories than active adults because their metabolism slows and activity decreases. Switch to a senior formula with joint-supporting ingredients like glucosamine and reduced fat content.
