The Cavalier King Charles Spaniel is the breed most strongly associated with chronic pancreatitis — a smouldering, easily-missed inflammation of the pancreas that drives recurrent vomiting, abdominal pain and loose stools, and which is often never diagnosed in life. Because dietary fat is the main driver of pancreatic workload, a lower-fat, highly digestible diet fed in small measured portions is the cornerstone of keeping this breed's digestion settled. Cut fatty treats and table scraps entirely, and watch for warning signs of a flare — repeated vomiting, a hunched or tender tummy, lethargy, off food or weight loss — which warrant prompt veterinary care. As a breed also prone to heart disease, keeping a Cavalier lean matters for the whole dog, not just the gut.

We've taken our full grain-free roundup and assessed each food specifically for Cavalier King Charles Spaniel suitability. Whether you have a puppy or a senior Cavalier King Charles Spaniel, here's what the breed needs — and which foods deliver it. (Looking for a different breed? Browse our full by-breed index.)

What Cavalier King Charles Spaniels Need from Their Food

Cavalier King Charles Spaniels are a small breed weighing 5.4-8kg, with a lifespan of 12-15 years. They have a moderate activity level, which shapes their nutritional needs:

  • Protein: 24-28% crude protein — essential for muscle maintenance.
  • Fat: 8-12% — a moderate range that supports their exercise needs.
  • Daily intake: Approximately 90-140g dry per day (350-500 kcal), though this varies with activity level and age.
  • Highly digestible single protein — particularly important for this breed.
  • Low fat to reduce pancreatic workload — particularly important for this breed.
  • Prebiotics and probiotics for gut flora — particularly important for this breed.
  • Omega-3 for heart and coat — particularly important for this breed.

Common Health Issues That Affect Food Choice

Cavalier King Charles Spaniels are prone to:

  • Chronic pancreatitis
  • Exocrine pancreatic insufficiency (epi)
  • Sensitive stomach / chronic gastrointestinal signs
  • Mitral valve disease (heart murmur)
  • Syringomyelia
  • Obesity

Several of these conditions are either caused by or worsened by diet. Grain-free food with quality protein sources can help manage inflammation and reduce allergic reactions.

Common Food Sensitivities

Cavalier King Charles Spaniels frequently develop sensitivities to: high-fat foods and rich treats, table scraps, fillers and poor-quality protein. If your Cavalier King Charles Spaniel has itchy skin, recurring ear infections, or digestive issues, consider an elimination diet starting with a single novel protein source.

Frequently Asked Questions

What is the best dog food for a Cavalier King Charles Spaniel?

The best food for a Cavalier King Charles Spaniel is a lower-fat, highly digestible recipe built on a named single protein, fed in small measured portions. Because the breed is strongly prone to chronic pancreatitis, keeping dietary fat down matters more than any trendy ingredient, and helps protect a breed that is also vulnerable to heart disease and weight gain.

How much should I feed a Cavalier King Charles Spaniel?

An adult Cavalier weighing 5.4 to 8kg eats roughly 90 to 140g of dry food daily, split across two small meals. Weigh portions accurately, keep treats minimal and avoid fatty table scraps entirely — fat is the main driver of pancreatic flare-ups in this breed.

Why do Cavalier King Charles Spaniels have sensitive stomachs?

Cavaliers are the breed most strongly associated with chronic pancreatitis — a smouldering inflammation of the pancreas that causes recurrent vomiting, tummy pain and loose stools, and is often never diagnosed in life. This makes the breed prone to ongoing digestive upset, so a clean, digestible, lower-fat diet is the most reliable way to keep their gut settled.

What is chronic pancreatitis in Cavalier King Charles Spaniels?

Chronic pancreatitis is a long-running inflammation of the pancreas. Post-mortem studies have found evidence of it in around half of Cavaliers examined, with a relative risk roughly three times that of other breeds, and it worsens with age. Most cases are missed in life. Warning signs include repeated vomiting, a hunched or tender abdomen, lethargy, going off food and weight loss — if you see these, see your vet promptly, as it needs veterinary diagnosis and management.

Is low-fat food good for Cavalier King Charles Spaniels?

Yes — because dietary fat is the biggest driver of pancreatic workload, a lower-fat, highly digestible diet helps reduce the risk of pancreatitis flare-ups in a breed that is strongly predisposed to chronic pancreatitis. Always avoid fatty treats and rich table scraps, and discuss any therapeutic diet with your vet.
