Sussex Spaniel Diet & Feeding Guide

Back to Sussex Spaniel Overview

Nutrition is a cornerstone of Sussex Spaniel health. An adult Sussex Spaniel weighing 16–20kg typically requires 750–950 kcal of high-quality food per day, split across two meals to support consistent energy levels and healthy digestion. Sussex Spaniels have relatively modest activity requirements, which means overfeeding is a real risk; consistent portion control and low-calorie treats are advised. Always adjust portions based on your dog's individual weight, life stage, and activity level, and consult your vet before making significant dietary changes.
