This vet’s approved dog calorie calculator is created for pet owners to determine the optimal daily caloric intake for their canine companions.
This takes into account various factors such as age, weight, activity level, and reproductive status to provide a tailored estimate of a dog’s energy requirements.
Consider a 5-year-old neutered Labrador Retriever weighing 70 pounds with moderate activity. The dog calories intake calculator suggest a daily intake of approximately 1,400 calories to maintain its current weight.

Dog Calorie Calculation Formula
The Resting Energy Requirement (RER) equation estimates the basic energy needs of a dog at rest:
RER = 70 x (body weight in kg)^0.75Once the RER is determined, it’s multiplied by a factor based on the dog’s life stage and activity level to calculate the Daily Energy Requirement (DER):
- Neutered adult: RER x 1.6
- Intact adult: RER x 1.8
- Active, working dog: RER x 2-5
- Puppy 0-4 months: RER x 3
- Puppy 4-12 months: RER x 2
Let’s calculate the DER for a 30 kg (66 lbs) neutered adult dog:
RER = 70 x (30)^0.75 ≈ 1,030 kcal/dayDER = 1,030 x 1.6 ≈ 1,648 kcal/dayThis dog would need approximately 1,648 calories per day to maintain its weight.
How do I calculate how many calories my dog needs?
To determine your dog’s caloric needs:
- Weigh your dog accurately.
- Assess their body condition score (BCS) on a scale of 1-9 (ideal is 4-5).
- Consider their activity level (sedentary, moderate, active, highly active).
- Factor in life stage (puppy, adult, senior).
- Note any health conditions or medications.
Imagine you have a 2-year-old spayed female Border Collie weighing 18 kg (40 lbs) with a BCS of 5 and high activity level.
Calculate RER: 70 x (18)^0.75 ≈ 700 kcal/day
Apply activity factor: 700 x 2 (for active dogs) = 1,400 kcal/day
This Border Collie would need approximately 1,400 calories daily to maintain her weight and support her high activity level.
How many calories does my dog burn?
Dogs burn calories through various activities:
- Basal metabolism: 70% of daily energy expenditure
- Physical activity: 20-30% of energy use
- Thermoregulation: maintaining body temperature
- Digestion: processing food
The exact number of calories burned depends on factors such as breed, size, age, and activity level. A general estimate is that dogs burn about 0.8 calories per pound per hour at rest.
For our Border Collie:
- At rest: 40 lbs x 0.8 cal/lb/hour x 24 hours ≈ 768 calories/day
- During a 30-minute intense play session: Additional 100-200 calories
Total daily burn: ~900-1,000 calories
How many calories does my dog need to lose weight?
For healthy weight loss, dogs should lose 1-2% of their body weight per week. To achieve this, reduce their daily caloric intake by 10-20% while maintaining or increasing exercise.
Let’s say your dog overweight at 22 kg (48 lbs) and needs to lose 4 kg:
- Current maintenance calories: 1,400 kcal/day
- Reduced intake for weight loss: 1,400 x 0.8 = 1,120 kcal/day
