Rat Terrier Diet & Feeding Guide

Back to Rat Terrier Overview

Nutrition is a cornerstone of Rat Terrier health. An adult Rat Terrier weighing 5–11kg typically requires 500–600 kcal of high-quality food per day, split across two meals to support consistent energy levels and healthy digestion. Small breeds can experience hypoglycaemia if meals are skipped; regular feeding times are especially important for Rat Terrier puppies. Always adjust portions based on your dog's individual weight, life stage, and activity level, and consult your vet before making significant dietary changes.
