Sussex Spaniel Feeding Guide
How much to feed your Sussex Spaniel — daily calories, portion sizes, and feeding schedule
Originating in England, the Sussex Spaniel is a medium-sized sporting breed that currently holds the #116 spot in AKC registrations. The only spaniel breed that routinely 'gives tongue' (barks) while working in the field, allowing hunters to follow their progress through dense brush. As a medium Sporting breed, the Sussex Spaniel was built for an active life of retrieving, flushing, and swimming. This athletic heritage directly shapes their nutritional needs — they require a protein-rich diet that supports sustained muscle performance and recovery. An adult Sussex Spaniel needs between 752 and 907 calories per day, though this varies with age, weight, activity level, and individual metabolism.
Feed an adult Sussex Spaniel approximately 0.5–0.9 cups of quality kibble daily, split into two meals. Males (35–45 lbs) may need slightly more than females (29–39 lbs). Males 40-44 lbs, females 35-40 lbs. Heavy for their height at 13-15 inches. Must be kept lean to protect the spine. The heaviest spaniel per inch of height.. With moderate energy (2/5), portions at the middle of guidelines usually suffice.

Feeding Strategy for Sussex Spaniels
With a calm, low-energy temperament, the Sussex Spaniel is particularly susceptible to overfeeding. Their daily requirement of 2-2.4 cups may seem surprisingly small, but exceeding it regularly leads to weight gain. A weight-management or light formula can help, and measuring every meal with a proper cup — not estimating — is essential for this breed.

Exercise & Feeding for Sussex Spaniels
The Sussex Spaniel has modest exercise needs — 20-30 minutes of gentle walks and indoor play daily is usually sufficient. Because of their low activity level, there is rarely a need to adjust food intake for exercise. The bigger risk is overfeeding a relatively sedentary dog. If your Sussex Spaniel gets less activity than usual (bad weather, recovery from illness), consider reducing portions by 10%.
Joint Health & Nutrition
Joint health is a primary nutritional concern for Sussex Spaniels, which are predisposed to Hip Dysplasia. Diet plays a preventive and management role at every life stage. For puppies, controlled growth rate and proper calcium-phosphorus ratios protect developing joints. For adults, maintaining ideal body weight reduces mechanical stress on joints. Specific nutrients can slow cartilage degradation and reduce inflammation.
Recommended Joint Supplements
Heart-Supportive Nutrition
Sussex Spaniels have a genetic predisposition to Heart Conditions, making heart-supportive nutrition especially important. Choose foods naturally rich in taurine (found in animal proteins, especially dark meat and organ meats) and L-carnitine. Keep sodium moderate — not salt-free, but avoid high-sodium treats and table scraps. The FDA has investigated potential links between grain-free diets and dilated cardiomyopathy (DCM); while research is ongoing, discussing diet choices with your veterinarian is prudent for this breed. Omega-3 fatty acids from fish oil have demonstrated cardiovascular benefits in dogs, supporting healthy heart rhythm and reducing inflammation.
Thyroid Health & Diet
Hypothyroidism is a recognized concern in Sussex Spaniels, affecting metabolism, weight, coat quality, and energy level. A Sussex Spaniel with untreated hypothyroidism may gain weight despite eating normal portions, develop a thin or dull coat, and become lethargic. If your Sussex Spaniel shows these signs, a simple blood test can confirm the diagnosis. While thyroid medication (levothyroxine) is the primary treatment, dietary support matters: ensure adequate iodine and selenium in the diet, maintain strict portion control to prevent weight gain, and consider a weight-management formula if your dog is on thyroid medication but still struggling with weight.
Common Feeding Mistakes to Avoid
Overfeeding because the Sussex Spaniel always seems hungry
Some breeds appear perpetually hungry due to genetics or behavior. Stick to measured portions and use low-calorie treats like baby carrots, green beans, or ice cubes. If your Sussex Spaniel inhales food, try a slow-feeder bowl.
Skipping joint supplements until problems appear
For breeds predisposed to joint issues, preventive supplementation with glucosamine and omega-3 fatty acids can help protect cartilage before damage occurs. Starting these supplements early — even at 1-2 years old — is more effective than waiting for symptoms.
Blaming laziness for weight gain without checking thyroid
Sussex Spaniels are predisposed to hypothyroidism, which slows metabolism and causes weight gain even on normal portions. If your Sussex Spaniel is gaining weight despite measured feeding, ask your vet for a thyroid panel before simply cutting food.
Switching foods abruptly without a transition period
Any diet change — brand, flavor, or formula — should happen gradually over 7-10 days. Mix increasing amounts of the new food with decreasing amounts of the old. Abrupt switches cause digestive upset (diarrhea, vomiting, gas) in most dogs, Sussex Spaniels included.
Not accounting for treats in the daily calorie budget
Treats should never exceed 10% of your Sussex Spaniel's daily calorie intake. A single dental chew can contain 70-90 calories — significant for a dog that only needs 600 calories per day. Subtract treat calories from meal portions.

Breed-Specific Nutritional Needs
Based on health conditions common in Sussex Spaniels, consider these nutritional adjustments:
Glucosamine & Chondroitin
Add a joint supplement with glucosamine (500-1000mg) and chondroitin. Consider foods with added omega-3 fatty acids (EPA/DHA) to reduce inflammation.
Taurine & L-Carnitine
Choose foods rich in taurine and L-carnitine. Moderate sodium intake. Omega-3 fatty acids from fish oil support cardiovascular health.
Iodine & Selenium
Ensure adequate iodine and selenium in the diet. Weight management is important as hypothyroidism can cause weight gain.
Sussex Spaniel Ideal Weight
Assessing your Sussex Spaniel's body condition (healthy range: 35–45 lbs): Rib check: Run your hands along the ribcage—you should feel individual ribs under a slight fat layer. Overhead view: A defined waist should be visible between ribs and hips. Side profile: The abdomen should tuck upward behind the last rib. Overweight Sussex Spaniels face higher risks of Intervertebral Disc Disease, joint problems, and shortened lifespan.
Male Sussex Spaniel
35-45 lbs
16-20 kg
Female Sussex Spaniel
29-39 lbs
13-18 kg
