Nutrition is a cornerstone of Cavalier King Charles Spaniel health. An adult Cavalier King Charles Spaniel weighing 5.5–8kg typically requires 400–500 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 Cavalier King Charles Spaniel 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.
Portion sizes are approximate guidelines for a small-breed dog. Adjust based on your dog's individual weight, age, and activity level. Always consult your vet.
