How Much to Feed a Newfypoo

Large breeds such as the Newfypoo need fewer calories per pound than small dogs — metabolic rate scales with body surface, not weight, which is exactly what the RER exponent (kg^0.75) captures. At 90 lbs that works out to about 1809 kcal per day. Resist rounding portions up “because he's big”: excess weight is the single largest controllable risk factor for hip and elbow problems in large dogs.

At a typical 90 lbs (40.8 kg), the Newfypoo's resting energy requirement is 1131 kcal; with the adult, neutered/spayed multiplier of 1.6 the daily budget reaches 1809 kcal. In practical terms that is 476 g (16.8 oz) of typical dry food, or about 4.8 measuring cups. For dogs this size, buying food by the large bag and weighing portions saves real money — a 10% overfeed wastes roughly a bag per year.

These numbers are a starting point, not a prescription. The calculator supports every life stage (puppy, puppy, adult, neutered/spayed, adult, intact, active / working, senior, weight loss plan) — a puppy can need two to three times the adult allowance, while a senior or a dog on a weight-loss plan needs noticeably less. Recheck the numbers after any change in weight, activity, food brand or neutering status, and always transition between foods gradually over 7–10 days. For medical conditions, pregnancy or lactation, follow your veterinarian's feeding plan instead.
