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.
The Newfoundland is a giant-size breed weighing about 100-150 lb as an adult. As a general guide, a healthy adult needs roughly 1958-2985 kcal a day at maintenance, usually fed as 2-3 smaller meal(s) daily. For its size, the typical choice is large/giant-breed adult formula; controlled-calcium LARGE-BREED PUPPY formula through the extended growth period (AAFCO >70 lb-adult clause).
Some breeds have specific feeding considerations — talk to your veterinarian about what is right for your individual dog. These are informational estimates computed from the published NRC energy formula, not a feeding prescription — your dog's real needs vary with age, body condition, neuter status and activity, so confirm the plan with your veterinarian.
Portioning: split daily ration across 2-3 smaller meals. Kibble size: large / giant kibble.

How we estimate these calories
Every figure here is computed from the published veterinary energy formula RER = 70 × (body weight in kg)^0.75, then multiplied by the standard MER life-stage factor (neutered 1.6, intact 1.8, puppy 2.0–3.0, senior 1.2–1.4). We apply it across the breed's adult-weight range. It is a transparent estimate, not a measurement of your individual dog — confirm the plan with your vet.
