Dog Food & Calorie Calculator

Underfeeding stunts growth, while overfeeding leads to obesity and joint issues. Use our veterinary math calculator to determine your dog's exact daily caloric requirements (DER) based on their weight and lifestyle.

How the Calorie Math Works

Our calculator first determines your dog's Resting Energy Requirement (RER). This is the baseline number of calories they burn just staying alive. The formula for this is:

RER = 70 × (Body Weight in kg)^0.75

After calculating the RER, we multiply it by a life-stage coefficient to determine their Daily Energy Requirement (DER). For example, a growing puppy needs up to 3x their RER, while a neutered adult dog only needs 1.6x their RER.

Puppy Growth Chart by Breed Size

Track your puppy's development milestones from 3 months to adulthood across all major size categories.

Age Toy Small Medium Large Giant
3 months 2-4 lbs 6-10 lbs 12-20 lbs 25-35 lbs 35-45 lbs
6 months 4-8 lbs 12-18 lbs 25-40 lbs 45-60 lbs 60-80 lbs
Adult (1-2 yrs) 5-12 lbs 15-22 lbs 30-55 lbs 60-95 lbs 100-150 lbs

Other Growth-Influencing Factors

While breed genetics set the foundation for your puppy's ultimate size, several environmental factors play a crucial role in their development:

  • Nutrition: A balanced, age-appropriate diet is vital. Overfeeding can lead to rapid growth and joint problems, while underfeeding stunts development.
  • Genetics: Mixed breeds inherit a combination of traits. Looking at the size of the parents (especially the mother) provides strong clues.
  • Spaying/Neutering: Fixing your puppy before they reach full maturity can slightly alter the closure of their growth plates, sometimes resulting in a taller dog.
  • Health & Parasites: Severe intestinal parasites or chronic illness during puppyhood can impede calorie absorption and stunt growth.
