Ingredients List

  • 1 (3.75 oz) can wild-caught sardines in water (no salt added), drained: $2.50
  • 1 cup rolled oats (uncooked, gluten-free if needed): $0.50
  • 1/4 cup unsweetened plain applesauce: $0.20
  • 1 large egg: $0.30
  • 1 tablespoon olive oil: $0.10
  • Total Estimated Cost: $3.60

You can swap the sardines for canned salmon (in water, no salt) if your dog prefers. If your dog is allergic to eggs, a “flax egg” (1 tbsp ground flaxseed mixed with 3 tbsp water, let sit for 5 minutes) can work as a binder.

Step-by-Step Instructions

  • Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
  • In a medium bowl, mash the drained sardines thoroughly with a fork.
  • Add the rolled oats, applesauce, egg, and olive oil to the bowl with the sardines.
  • Mix everything together until it forms a thick, uniform dough. It will be a bit sticky.
  • Drop small spoonfuls (about 1 teaspoon each) of the mixture onto the prepared baking sheet. You can flatten them slightly with the back of a spoon.
  • Bake for 20-25 minutes, or until the treats are golden brown and firm to the touch.
  • Let them cool completely on a wire rack before serving. This helps them firm up and become less crumbly.

Look, prepping and cooking for your dog is great, but sometimes you might be too tired or maybe a tad lazy, or maybe you just want to give yourself a well deserved break.

Feeding Guidelines

  • These are treats, not a meal replacement.
  • For small dogs (under 20 lbs): 1-2 treats per day.
  • For medium dogs (20-50 lbs): 2-3 treats per day.
  • For large dogs (over 50 lbs): 3-4 treats per day.
  • Adjust based on your dog’s activity level and overall caloric intake. An active Border Collie might need more than a sleepy Bulldog.
  • Puppies and senior dogs might need smaller, softer pieces. Always consult your vet for precise feeding advice, especially if your dog has underlying health conditions or allergies.

Nutritional Benefits of the Recipe

  • Sardines: Packed with Omega-3 fatty acids (EPA and DHA), which are powerful anti-inflammatories. They help reduce skin irritation, improve coat shine, and support overall immune health. They also provide essential protein and Vitamin D.
  • Rolled Oats: A great source of soluble and insoluble fiber, which aids digestion and can help remove toxins from the body. They are also gentle on sensitive stomachs and provide B vitamins for energy and healthy skin cells.
  • Egg: Provides high-quality protein, amino acids, and fatty acids crucial for skin and coat health. It also contains biotin, a B vitamin often associated with healthy skin and nails.
  • Olive Oil: A healthy fat that adds Omega-6 fatty acids, further supporting skin hydration and elasticity. It also provides antioxidants.

Storage and Serving Tips

  • Store these treats in an airtight container in the refrigerator for up to 5-7 days.
  • For longer storage, freeze them in a single layer on a baking sheet, then transfer to a freezer-safe bag or container. They can be frozen for up to 2-3 months.
  • Thaw frozen treats in the refrigerator overnight or microwave for a few seconds until defrosted.
  • Serve them at room temperature or slightly warmed. You can offer them as a reward, a snack, or crumble a small piece over their regular food for an extra boost.

Common Questions & Troubleshooting

Why are my treats crumbly?

This can happen if the mixture was too dry or baked for too long. Make sure to mash the sardines well and don’t overbake. Adding a tiny bit more applesauce or another half egg can sometimes help with binding.

Can I add other ingredients?

Yes, but be careful. A sprinkle of dried parsley for fresh breath is fine. Avoid anything toxic like onions or garlic, and introduce new ingredients slowly to watch for sensitivities. Always check if an ingredient is dog-safe first.

My dog won’t eat them, what now?

Some dogs are picky. Try crumbling a treat over their regular food to get them used to the smell and taste. You can also try using canned salmon instead of sardines, as some dogs prefer the flavor.
