Dog Calorie Calculator

Calculate how many calories your dog needs daily based on weight, age, and activity level.

Understanding Your Dog's Calorie Needs

Just like humans, every dog has unique nutritional requirements. A dog's daily calorie needs are determined by several factors including body weight, age, activity level, and whether they're spayed or neutered. Understanding these needs is crucial for maintaining your dog's optimal health and preventing obesity-related issues.

The Resting Energy Requirement (RER) formula provides a scientific baseline: RER = 70 × (body weight in kg)^0.75. This is then multiplied by an activity factor ranging from 1.2 for sedentary dogs to 2.0 or higher for working breeds. Puppies, pregnant dogs, and lactating mothers require significantly more calories.

🐕

Sedentary Dogs

RER × 1.2-1.4

🏃

Active Dogs

RER × 1.5-1.8

💪

Working Dogs

RER × 2.0-5.0

Frequently Asked Questions

How many calories does my dog need per day?

Calorie needs depend on weight, age, and activity. A typical formula is RER (Resting Energy Requirement) = 70 × (body weight in kg)^0.75, then multiplied by an activity factor (1.2-2.0). Active dogs need more calories than sedentary ones.

Should I reduce calories for overweight dogs?

Yes, reduce calories by 20-30% for weight loss. A gradual approach is best - aim for 1-2% body weight loss per week. Consult your vet for a proper weight loss plan.

Do puppies need more calories than adult dogs?

Yes, puppies need 2-3 times more calories per pound than adults due to rapid growth. This requirement decreases as they mature, typically around 12-18 months for most breeds.

How does activity level affect calorie needs?

Highly active dogs (working, sporting) may need 1.5-2x more calories than sedentary dogs. Moderately active dogs need about 1.3-1.5x the base requirement.

Should senior dogs eat fewer calories?

Generally yes, senior dogs are less active and have slower metabolisms. Reduce calories by 10-20% for seniors, but ensure adequate protein for muscle maintenance.

How do I know if I'm feeding enough?

Monitor your dog's body condition score. You should feel ribs easily but not see them. Adjust portions based on weight changes every 2-4 weeks.
