Dog activity trackers grew 80% YoY. Real-time burn data helps owners adjust daily portions.
You flip the dog food bag over and the feeding chart says "3–4 cups for a 30 lb dog." But your dog gained weight on that amount last month. Sound familiar? Pet food bag guidelines overestimate actual needs by up to 25% for most neutered adult dogs.
This isn't an accident — guidelines are deliberately set for the most active, largest-framed intact adult in a weight category. The result: a canine obesity epidemic affecting over 56% of US dogs. The solution is calculating your individual dog's Resting Energy Requirement (RER) — the same formula used by board-certified veterinary nutritionists in clinical practice.
| Size | Weight | Adult Calories/Day | Example Breeds |
|---|---|---|---|
| Small | 2–9 kg | 185–470 kcal | Chihuahua, Shih Tzu, Dachshund |
| Medium | 10–25 kg | 470–950 kcal | Beagle, Border Collie, Cocker Spaniel |
| Large | 26–45 kg | 950–1,500 kcal | Labrador, German Shepherd, Boxer |
| Giant | 46+ kg | 1,500–2,200+ kcal | Great Dane, Rottweiler, St. Bernard |
Use a recent weigh-in. Enter in kg or lbs — the calculator converts automatically.
Puppy, Adult, or Senior — each applies a clinically validated energy multiplier to the RER baseline.
From sedentary to highly active. A working dog needs 40–50% more calories than a sedentary dog of the same weight.
Spayed/neutered, pregnant, nursing, or weight loss goal — each significantly changes the result.
