What does a Sussex Spaniel need from its diet?

Sussex Spaniels have a sturdy, dense build and tend to be moderately active. Their short legs and low-slung frame mean they burn calories more slowly than longer-legged breeds, so they can gain weight easily if portions aren't controlled. For many owners, careful portioning is the simplest and most effective way to help their dog maintain a healthy weight.

Beyond managing calories, these dogs benefit from diets that support strong muscles and healthy joints. Regular daily exercise - typically 60–90 minutes of walking - helps, but the right nutrition also reduces strain on hips and knees. Foods that promote good digestion ensure nutrients are absorbed effectively and help your dog feel comfortable day to day.

• Balanced calories - avoid excess energy for a low to moderate activity level
• Joint-supporting nutrients to help maintain mobility
• Digestive-friendly ingredients to support nutrient absorption and gut comfort

Which nutrients support mobility and weight control in Sussex Spaniels?

Lean animal protein is essential: it preserves muscle without adding unnecessary calories, helping your dog stay strong yet lean. Omega-3 fatty acids, found in salmon and concentrated omega oils, reduce inflammation around joints - a real benefit for a compact, heavier-set breed.

Natural vitamins and minerals, combined with the benefits of fresh meats, support cartilage and joint resilience. Gut-friendly fibre and prebiotics such as chicory root and yucca - ingredients used in Marleybones recipes - promote steady, healthy digestion. Controlled, balanced fats provide slow-release energy suited to a Sussex Spaniel's easy-going lifestyle.

• Lean proteins: chicken, beef, lamb and salmon to support muscle strength
• Omega-3s: salmon, flaxseed and omega oils for joint and skin health
• Natural prebiotics: chicory root and yucca to aid digestive comfort
• Balanced fats and lower-calorie recipes to make portion control easier

How to choose and serve the right food for your Sussex Spaniel

Every Sussex Spaniel is unique. Keep an eye on your dog's activity level and adjust portions so they stay lean and energetic. Splitting the daily allowance into two smaller meals - morning and evening - aids digestion, helps maintain steady energy and reduces the small risk of bloating.

Look for recipes that are AAFCO-aligned and list clear, high-quality ingredients. Marleybones Pantry Fresh® meals provide complete nutrition and reliable digestibility. For older dogs or those with mild joint stiffness, a little omega oil or a gentle joint supplement at mealtimes can be a helpful addition.

• Weigh and check condition regularly - if ribs become hard to feel, reduce calories.
• Choose complete, balanced meals designed for all life stages.
• Use supplements thoughtfully to support gut and joint health when needed.
