Portuguese Water Dog Diet & Feeding Guide

Back to Portuguese Water Dog Overview

Nutrition is a cornerstone of Portuguese Water Dog health. An adult Portuguese Water Dog weighing 16–25kg typically requires 1200–1500 kcal of high-quality food per day, split across two meals to support consistent energy levels and healthy digestion. Their high energy output means Portuguese Water Dogs need a calorie-dense diet — look for a working- or active-dog formula with at least 25% protein content. Always adjust portions based on your dog's individual weight, life stage, and activity level, and consult your vet before making significant dietary changes.
