Step-by-Step Instructions

  • Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
  • Drain the can of sardines thoroughly. Put the drained sardines into a medium mixing bowl.
  • Mash the sardines really well with a fork until they are a smooth paste. Break up any bones if you see them, they are usually soft.
  • Add the rice flour to the mashed sardines.
  • Mix everything together with your hands or a spoon until a firm dough forms. It might look a little crumbly at first, but keep working it.
  • Roll out the dough between two sheets of parchment paper. Roll it to about 1/8 to 1/4 inch thick.
  • Use a cookie cutter or a knife to cut the dough into small treat shapes. Think bite-sized for your dog.
  • Place the cut treats onto the prepared baking sheet.
  • Bake for 20-25 minutes. The crackers should be firm and slightly golden around the edges.
  • Let them cool completely on a wire rack before giving them to your dog. They will crisp up more as they cool.

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, so feed them in moderation.
  • Small dogs (under 20 lbs): 1-2 small crackers per day.
  • Medium dogs (20-50 lbs): 2-4 small crackers per day.
  • Large dogs (over 50 lbs): 4-6 small crackers per day.
  • For puppies, senior dogs, or pregnant/nursing dogs, adjust amounts. Puppies need more calories, but treats should still be limited. Seniors might need fewer due to lower activity.
  • If your dog is overweight, cut back on treats. If underweight, these can be a healthy, calorie-dense addition.
  • Always talk to your vet to get specific feeding advice for your dog, especially if they have health issues or unique dietary needs.

Nutritional Benefits of the Recipe

  • Sardines: These tiny fish are powerhouses. They’re rich in Omega-3 fatty acids (EPA and DHA), which are great for skin and coat health, reducing inflammation, and supporting brain and joint function. They also provide high-quality protein and essential vitamins like D and B12, and minerals like calcium and phosphorus.
  • Rice Flour: A gluten-free carbohydrate source that’s easy on sensitive stomachs. It provides quick energy without common allergens found in wheat.
  • Overall: This recipe offers a fantastic boost of healthy fats and protein, essential for maintaining muscle mass, energy levels, and overall vitality. The calcium from the soft bones in the sardines supports strong bones and teeth.

Storage and Serving Tips

  • Once cooled, store these crackers in an airtight container in the refrigerator for up to 5-7 days.
  • For longer storage, you can freeze them for up to 2-3 months. Thaw them in the fridge overnight or let them sit at room temperature for a bit before serving.
  • You can serve these treats at room temperature.
  • Some dogs might enjoy them slightly warmed in the microwave for a few seconds.
  • These are great as a stand-alone treat, or you can crumble a piece over their regular kibble to make mealtime more exciting.

Common Questions & Troubleshooting

Can I use sardines in oil?

It’s best to stick to sardines packed in water with no added salt. The oils can sometimes upset a dog’s stomach and add unnecessary calories and fats that might not be healthy for them.

My dough is too sticky/crumbly. What should I do?

If it’s too sticky, add a tiny bit more rice flour, a tablespoon at a time, until it’s workable. If it’s too crumbly, add a teaspoon of water or a tiny bit more of the mashed sardines until it comes together. The consistency of canned sardines can vary.

Are these treats safe for puppies?

Yes, in small amounts, these treats are safe for most puppies once they are weaned and eating solid food. The Omega-3s are especially beneficial for brain development. Just make sure the pieces are very small for tiny pups.

Can I add other ingredients?

For this specific “2-ingredient” recipe, we’re keeping it simple. But yes, you can get creative with other dog-safe additions like finely chopped parsley for fresh breath, or a sprinkle of turmeric for its anti-inflammatory properties. Just make sure any additions are safe and in small amounts.
