What formulas does the dog feeding planner use?

It uses RER = 70 x body weight(kg)^0.75, then applies age, activity, and neuter factors to estimate a maintenance energy requirement. The result is a starting estimate, not a veterinary diet prescription.

Why does food density matter?

The cup estimate divides food calories by the kcal per cup printed on the food label. Two foods can have very different calorie density, so cups per day change even when the calorie target stays the same.

How does the treat budget work?

The planner subtracts entered treat calories from the MER estimate and flags treats above 10% of MER. Treats can crowd out complete food, so the remaining food portion should be watched carefully.

Can this calculator replace my veterinarian?

No. Veterinary guidance is important for puppies, seniors, pregnancy or lactation, obesity, disease, prescription diets, appetite changes, and any planned weight-loss program.

Why does my dog need more or fewer calories than the estimate?

Energy needs vary by body condition, lean mass, breed tendency, temperature, medication, training load, health status, and metabolism. Track weight and body condition and adjust with veterinary guidance.

Visual Breakdown

Veterinary note: This planner is an educational starting point for healthy dogs. Puppies, seniors, pregnant or lactating dogs, dogs with obesity, and dogs with medical conditions need veterinary guidance before changing calories or food amount.

How the Canine Feeding Planner Works

This calculator estimates a daily calorie target for dogs from body weight, body condition goal, age group, activity level, neuter status, treat calories, and the calorie density printed on the food label. It does not choose a diet or diagnose weight problems.

RER and MER Formula

The base energy estimate is RER = 70 x body weight(kg)^0.75. The planner uses target weight for weight-loss mode when the target is lower than current weight; otherwise it uses current weight. It then estimates MER by multiplying RER by the selected activity factor, age factor, and a neuter factor when selected.

With the default 50 lb adult neutered dog, normal activity, 350 kcal/cup food, and 50 treat calories, the calculator estimates about 727 kcal RER, 917 kcal MER, 2.48 cups per day, and 1.24 cups per meal for two meals.

Food Cups and Treats

Cups per day are calculated as (MER - treat calories) / food kcal per cup. This is why the kcal/cup value matters. A 350 kcal/cup food and a 450 kcal/cup food produce different cup amounts for the same dog.

The treat budget uses a common 10% of daily calories rule. If treats exceed that share, complete food may be reduced enough to affect nutrient balance. Treats, chews, dental products, table food, training rewards, and medication pockets should all be counted.

Weight Goals

The timeline uses about 1.5% of current body weight per week as a simple projection. That is only a planning estimate. Dogs with obesity, pain, endocrine disease, kidney disease, gastrointestinal disease, or prescription diets should have weight-loss plans supervised by a veterinarian.

Source Notes

The Merck Veterinary Manual describes RER, MER, and the large variability in pet energy requirements. AAHA's weight-management tip sheet uses the RER formula and ideal-weight planning for pet calorie estimates.

Frequently Asked Questions

It starts with RER = 70 x body weight(kg)^0.75 and then applies the selected age, activity, and neuter factors to estimate daily calories.

The calorie target did not change; the cup conversion changed. More calorie-dense food needs fewer cups for the same calories.
