Diabetic Dog Calorie Calculator
For a 30 lb (13.6 kg) dog that is about 694–794 kcal a day, split across two meals twelve hours apart.

Use the weight on the clinic scale, not a guess. If your vet set a target weight, enter that and pick the weight-loss band below.
Diabetic dogs are very often overweight at diagnosis, so this is the field that most often changes the answer.
For a diabetic dog, keep the activity level the same from day to day — a sudden increase in exercise can move blood glucose the same way a meal does.
This only divides the daily total. It does not change how many calories the day holds.
Read it off the pack. Many labels print kcal/kg — divide by 10 to get kcal per 100 g. 3,688 kcal/kg is 368.8 kcal per 100 g.

Pregnancy and diabetes both push energy needs outside the range a normal adult dog sits in, and both are situations where a wrong estimate matters more than an approximate one. The pages here handle them separately instead of offering one generic special factor: the pregnancy tool works by stage, because the energy cost of a litter rises late, and the diabetic tool starts from a daily band and splits it across the meals you actually feed. Neither diagnoses anything or adjusts insulin; they make the arithmetic explicit so your veterinary team can check it.
Constants this page uses, and where each one comes from
| Constant | What it is | Named source |
|---|---|---|
| 70 | RER scaling constant, 70 × kg0.75 | AAHA 2021, Box 1 — Energy Requirement Calculations |
| 0.75 | exponent applied to body weight in kilograms | AAHA 2021, Box 1 — Energy Requirement Calculations |
| 1.0–1.2 | factor band for weight loss | AAHA 2021, Box 1 — Energy Requirement Calculations |
| 1.0–1.2 | factor band for sedentary / inactive | AAHA 2021, Box 1 — Energy Requirement Calculations |
| 1.4–1.6 | factor band for typical adult, spayed/neutered | AAHA 2021, Box 1 — Energy Requirement Calculations |
| 1.6–1.8 | factor band for typical adult, intact | AAHA 2021, Box 1 — Energy Requirement Calculations |
| 1.6–2.0 | factor band for light work | AAHA 2021, Box 1 — Energy Requirement Calculations |
Where to start
Open the Pregnant Dog Calorie Calculator first. It is the more staged of the two: choose gestation weeks 1–4, 5–6, 7–8, week 9 or a week of lactation, and it applies that stage's multiplier and prints the daily kcal and the grams behind it.
What every tool here assumes
One set of inputs and one set of published constants, listed once here rather than repeated on every page.
- Resting energy requirement. RER = 70 × (body weight in kg)0.75, and both pages move the multiplier rather than the equation.
- Gestation is a multiplier on maintenance. 1.0 in weeks 1–4, 1.15 in weeks 5–6, 1.35 in weeks 7–8 and 1.5 in week 9, so early pregnancy costs almost nothing extra and the rise happens late.
- Lactation is the expensive part. Weeks 1–4 of lactation run 2.0 to 3.5 × the maintenance figure, and the litter-size route is 3.0 × RER for 1–3 pups, 3.5 for 4–6 and 4.0 for 7 or more.
- Diabetes uses the ordinary bands, split across meals. 1.0–1.2 × RER for controlled weight loss or a sedentary dog, 1.4–1.6 for a typical neutered adult, 1.6–1.8 intact, 1.6–2.0 for light work, then divided into the meals you actually feed.
- Premise. These pages are arithmetic, not veterinary advice — no diagnosis, no prescription diet, and no change to insulin, diet or feeding schedule should be made from them.
The other tool families
Pregnancy & Special Conditions is one of six families on the site. The other five are Calories & Feeding, Age & Growth, Feline, Food Safety, and Breed & Body Condition.
