What Cavalier King Charles Spaniels need most from their food
The Cavalier’s cardiac predisposition and silky coat shape their nutritional priorities:
Heart Health
Cavaliers are highly prone to mitral valve disease. A lean body weight and an omega-3-rich diet support cardiovascular health.
Coat Quality
The Cavalier’s silky, feathered coat depends on dietary protein and omega-3s. Fish oil supports coat health.
Weight Management
Lean, nutrient-dense food (not calorie-dense filler) helps maintain a healthy weight without overfeeding.
Ear Health
Long, low-set ears prone to infections often linked to food sensitivities. A simple, single-protein diet makes a known trigger easier to avoid.
Why freeze-dried raw is right for Cavalier King Charles SpanielsCavalier King Charles Spaniels
Cavalier King Charles Spaniels are predisposed to mitral valve disease — the breed’s most significant health concern. Diet cannot change the genetic predisposition, but keeping a Cavalier lean is one of the most useful things an owner controls, and an omega-3-rich diet supports normal heart function. The EPA and DHA in fish oil are particularly relevant.
The breed’s silky, feathered coat also depends on dietary quality, and the long, low-set ears are prone to infections that are sometimes linked to food sensitivities. A clean, omega-rich, whole-food diet addresses coat, ear, and cardiac considerations together.

The standard is King.
Loyal Saints was built because of one dog. King’s digestive sensitivities pushed Kristina Voltin to question the ingredients, processing and nutrition behind every bowl. She formulated a whole-food, freeze-dried raw diet from human-grade quality ingredients — food she felt confident feeding King every day. Every formula is held to that standard: would I feed this to King?
For Cavalier King Charles Spaniels owners navigating the same questions Kristina faced — about ingredients, about what’s really in the bag, about whether the food is actually good — Loyal Saints is the answer she built for them.

For a heart-predisposed breed, lean weight and an omega-rich diet matter. Removing fillers and synthetic additives supports the cardiovascular and ear health Cavaliers need.
Frequently Asked Questions
What is the best diet for a Cavalier’s heart health?
A complete diet that keeps your Cavalier lean, with omega-3s EPA and DHA to support normal heart function — alongside regular heart checks with your vet. Turkey + Salmon provides EPA and DHA from fish oil, supports lean weight through its low-filler profile, and avoids the additives and excess sodium common in processed food. Always work with your vet on cardiac management — diet is supportive, not a treatment.
How do I care for my Cavalier’s coat?
The silky, feathered Cavalier coat depends on dietary protein and omega-3 fatty acids. Turkey + Salmon delivers both. Most owners see improved coat quality within 4–8 weeks. Regular grooming of the feathering remains important alongside diet.
Why does my Cavalier get ear infections?
Cavaliers' long, low-set ears trap moisture, and food sensitivities are a common contributing factor. When food plays a part, a single-protein diet with no wheat, corn or soy makes the trigger easier to avoid. Routine ear cleaning and drying, and your vet’s care, do the rest.
How much should I feed my Cavalier King Charles Spaniel?
Cavaliers typically weigh 13–18 lbs and need about 1⅓–1⅔ cups of freeze-dried raw a day as a complete meal (Beef or Turkey + Salmon; 1½–1¾ cups of Chicken), split into two meals. Keeping a Cavalier lean is especially important for cardiac health — monitor body condition closely.
