What Makes This Recipe So Good

Rich in omega-3s
Sardines are one of the most concentrated natural sources of EPA and DHA. Studies show omega-3 fatty acids can reduce inflammatory skin conditions and improve coat shine in dogs when fed consistently.

High-quality protein
Sardines and eggs deliver complete amino acids that support skin repair, muscle maintenance, and immune health. I’ve found this combination especially useful for senior dogs and active breeds.

Digestible carbs and fiber
Sweet potato and brown rice provide steady energy and soluble fiber, which helps regulate bowel movements. Fiber intake has been shown to support gut health in over 70% of dogs with mild digestive issues.

Skin-loving micronutrients
Spinach, carrots, and blueberries contribute vitamins A, E, and antioxidants that support the skin barrier and cellular repair.

Easy and affordable
This recipe uses widely available ingredients, takes under an hour, and works well for batch cooking.

Ingredients

2 cans sardines in water (3.75–4.4 oz each), drained
1 cup cooked brown rice (unsalted)
1 cup cooked sweet potato, mashed
1/2 cup finely chopped spinach, lightly steamed
1/2 cup finely diced carrots, steamed until soft
1 large egg, scrambled with a splash of water
1 tablespoon olive oil or coconut oil
1 teaspoon ground flaxseed (optional)
2 tablespoons plain pumpkin puree (optional)
Pinch of turmeric (optional)
Dog-safe calcium source: 1/2 teaspoon eggshell powder or vet-approved supplement
Clean water or unsalted bone broth to adjust texture

Instructions

Cook the base
Prepare brown rice and steam the sweet potato and carrots until very soft. Lightly steam the spinach for 1–2 minutes.

Scramble the egg
Whisk the egg with a splash of water and cook in a nonstick pan without oil or seasoning.

Prep the sardines
Drain thoroughly and flake with a fork. I always check for hard bone fragments, even though most canned sardine bones are soft and digestible.

Combine
In a large bowl, mix rice, sweet potato, carrots, spinach, scrambled egg, and sardines.

Add extras
Stir in oil, flaxseed, pumpkin puree, and turmeric if using.

Balance calcium
Mix in eggshell powder or a vet-approved calcium supplement. I cannot stress enough how important this step is when feeding homemade food regularly.

Adjust texture
Add water or broth until the mixture is soft and scoopable.

Cool and serve
Allow food to reach room temperature before feeding.

Portion
Serve approximately 1/2 to 1 cup per 10 pounds of body weight per day, split into two meals. Adjust based on age, activity, and body condition.

Keeping It Fresh

Refrigerate
Store in an airtight container for up to 3 days.

Freeze
Freeze meal-sized portions for up to 2 months.

Reheat gently
Warm slightly with water; never serve hot.

Smell check
Fresh sardine food should smell clean and mild. If it smells sour, discard it.

Why This is Good for You

Healthy skin and a shiny coat are often outward signs of internal balance. I’ve seen dogs with chronic itching show visible improvement once omega-3s are introduced properly. Sardines help support the skin barrier, while fiber and slow carbs stabilize digestion.

Knowing exactly what’s in your dog’s bowl is invaluable when managing sensitivities, allergies, or recurring skin flare-ups.

What Not to Do

Don’t add salt, garlic, or onions
These are harmful to dogs.

Don’t use sardines in oil or sauce
Always choose sardines packed in water with no added salt.

Don’t rely on this recipe alone long-term
Homemade diets must be balanced over time with professional guidance.

Don’t skip calcium
Calcium is essential for bones, nerves, and muscle function.

Don’t switch abruptly
Transition over 4–7 days to avoid digestive upset.

Variations You Can Try

Grain-free option
Replace brown rice with additional sweet potato or cooked quinoa if tolerated.

Different greens
Swap spinach for kale or green beans, finely chopped and cooked.

Add probiotics
Stir in plain, unsweetened yogurt or a vet-approved probiotic at serving time.

Extra glow
A few drops of fish or salmon oil can increase omega-3 intake under vet guidance.

Low-fat tweak
Reduce added oil and increase vegetables for dogs needing calorie control.
