Dog Food by Breed Size: Every Class Compared
Every dog size class, side by side, with its typical weight range, food type, kibble size and meals per day. Pick a class to see the breeds in it, or use the calculator to estimate a portion for your dog. Informational guidance — not veterinary advice.
Informational, not a feeding prescription. These figures are general guidance, not veterinary advice. Calorie and portion ranges are transparently computed from the published NRC energy formula (RER = 70 × kg0.75) applied to the breed’s weight range — an estimate, not a per-dog prescription. Individual needs vary with metabolism, body condition, neuter status and activity. Confirm your dog’s plan with your veterinarian.
