4-Ingredient Sardine and Oatmeal Treats: A Fishy Delight for Your Pup
If your pup loves strong, savory tastes, these 4-Ingredient Sardine and Oatmeal Treats are going to be a hit. They’re packed with protein, easy to make, and full of nutrients that support your dog’s health. These treats aren’t just about flavor—they’re about giving your dog a snack that’s genuinely good for them. Even if you’re new to cooking for your dog, you’ll find this recipe simple and satisfying.
Sardines bring a rich, fishy flavor that dogs often adore, and the combination with oatmeal creates a chewy, hearty texture that makes each bite irresistible. This recipe is perfect for any dog owner who wants a quick, healthy treat without relying on processed snacks full of preservatives or fillers.
Ingredients You’ll Need

You don’t need a long list of fancy ingredients to make these treats. Everything you need is likely already in your kitchen:
- 1 can of sardines (packed in water or oil, drained)
- 1 cup of rolled oats (or oat flour if you want a smoother texture)
- 1 egg (to bind everything together)
- 1 tablespoon of olive oil (optional, for added healthy fats)
Each ingredient plays a crucial role. Sardines provide protein, omega-3 fatty acids, and essential nutrients like vitamin D and calcium. The oats add fiber to keep digestion healthy, the egg helps everything stick together while giving a little extra protein, and the olive oil keeps the treats moist while supporting heart and coat health.
This combination creates treats that are as nourishing as they are delicious. Every bite is a win for your dog’s taste buds and overall health.
Step-by-Step Instructions to Make Sardine and Oatmeal Treats
Prep the Ingredients
Start by preheating your oven to 350°F (175°C). Preheating ensures that the treats cook evenly and develop a slightly golden, firm texture. Line a baking sheet with parchment paper so that cleanup is easy and the treats don’t stick.
Mix the Dough
Drain the sardines and mash them in a bowl until they’re broken down into small, even pieces. It’s okay if it smells a little fishy—your dog will love it. Then, add the rolled oats, egg, and olive oil, and mix everything together until a dough forms. If the mixture feels too wet or sticky, sprinkle in a little extra oats until it’s workable.
Shape and Bake
Next, shape the dough into small balls or press it into cookie shapes. Wetting your hands slightly can help prevent sticking. Place the treats on the prepared baking sheet and bake for 20–25 minutes, or until they are firm and slightly golden on the edges.
Cool Before Serving

Once baked, allow the treats to cool completely before giving them to your dog. Hot treats can burn their mouths, so patience here makes the experience safer and more enjoyable for your pup.
Common Mistakes to Avoid
Even simple recipes can go wrong if a few details are missed. Here’s what to watch out for:
- Using sardines in brine or sauce: Stick to sardines packed in water or oil. Brines or sauces often contain salt or seasonings that aren’t safe for dogs.
- Overbaking: Treats should be firm but not rock-hard. Keep an eye on the last few minutes to prevent them from drying out.
- Skipping the cool-down: Never serve these treats while hot. Always let them cool completely.
- Too wet dough: If the dough sticks too much to your hands, add a little more oats until it’s manageable.
Alternatives and Variations
You can easily tweak this recipe to suit your dog’s taste or dietary needs:
- Canned salmon instead of sardines: Another tasty, protein-rich option that dogs love.
- Add parsley: Fresh parsley can help keep your dog’s breath smelling better.
- Use sweet potato: Replace half the sardines with mashed sweet potato for a milder flavor that still packs nutrients.
- Include a pinch of turmeric: Adds anti-inflammatory benefits and a fun golden color.
- Grain-free option: Swap the oats for coconut flour, but use less since coconut flour absorbs more moisture.
Storing Your Sardine and Oatmeal Treats
These treats keep well, so you can make a batch in advance. Store in an airtight container at room temperature for up to 5 days, keep them in the refrigerator for up to 2 weeks, or freeze for up to 3 months. Simply thaw as needed for a quick, healthy snack.
Health Benefits
These treats aren’t just tasty—they also provide several health benefits. Sardines are rich in omega-3s, which promote shiny coats, healthy skin, and strong joints. The high protein content makes them ideal for active dogs, while oats provide fiber to support digestion. They are low allergen, which is great for dogs sensitive to chicken or beef, and because they are homemade, they contain no artificial fillers or preservatives.
