Do you think​‍​‌‍​‍‌​‍​‌‍​‍‌ your dog is bored of the same treats that come from the store? Are you concerned about the long list of unknown ingredients in commercial dog treats?

It is quite difficult to figure out what is really good for them. However, what if you could prepare something incredibly delicious and nutritious that requires only two simple ingredients? Yes, it is possible, and I will show you how!​

Recipe Overview

• This homemade dog treat recipe is for Sardine & Flour Crackers.
• It uses just two ingredients that are packed with Omega-3s and complex carbs.
• Prep time: 10 minutes.
• Cook time: 25-30 minutes.
• Serving size: Makes about 30-40 small crackers.

Ingredients List

• 1 can (3.75 oz) sardines in water, no salt added (Cost: $2.50)
• 1.5 cups whole wheat flour (Cost: $0.75)
• Total Estimated Cost: $3.25

Suitable Substitutions:

• For the sardines: You can use sardines in olive oil (drain the oil first) or even pureed cooked salmon for a similar omega-3 boost.
• For the whole wheat flour: If your dog has a wheat allergy, oat flour or rice flour can be used. Just be aware the texture might be slightly different.

Step-by-Step Instructions

• Preheat your oven to 350°F (175°C).
• Get a baking sheet and line it with parchment paper. This helps prevent sticking.
• Open the can of sardines. Drain out all the water thoroughly.
• Place the drained sardines in a medium-sized mixing bowl.
• Use a fork to mash the sardines really well. You want them to be a smooth paste.
• Gradually add the whole wheat flour to the mashed sardines.
• Mix everything together. Start with a fork, then switch to your hands.
• Keep mixing until a firm dough forms. It should be easy to handle.
• If the dough seems too sticky, add a tiny bit more flour, about a tablespoon at a time.
• If it’s too dry, add a tiny splash of water, about a teaspoon at a time.
• Lightly flour a clean surface, like your kitchen counter.
• Roll out the dough using a rolling pin. Aim for about 1/8 to 1/4 inch thickness.
• Use a small cookie cutter or a knife to cut the dough into treat shapes.
• You can make squares, circles, or whatever your dog prefers.
• Carefully place the cut treats onto the prepared baking sheet.
• Bake for 25-30 minutes.
• Look for them to be golden brown and firm when touched.
• Once baked, turn off the oven.
• Leave the treats inside the cooling oven for another 15-20 minutes. This makes them extra crispy.
• Take them out and let them cool completely on a wire rack before serving.

Feeding Guidelines

• These treats are intended as a snack, not a meal replacement.
• Small dogs (under 20 lbs): 1-2 treats per day.
• Medium dogs (20-50 lbs): 2-4 treats per day.
• Large dogs (over 50 lbs): 4-6 treats per day.
• Puppies: Give small pieces and limit to 1-2 per day due to their sensitive stomachs.
• Senior dogs: These are easy to chew, but adjust quantity based on their activity level.
• High-activity dogs: Can have a few more, but always keep treats to less than 10% of their daily caloric intake.
• Always talk to your vet if you have questions about specific dietary needs for your dog.

Nutritional Benefits of the Recipe

• Sardines: These tiny fish are powerhouses. They provide excellent protein for muscle health. They are also packed with Omega-3 fatty acids, like EPA and DHA. These are great for a shiny coat, healthy skin, and support brain and joint health. Sardines are also a good source of Vitamin D and Calcium for strong bones.
• Whole Wheat Flour: This provides complex carbohydrates for sustained energy. It also offers dietary fiber, which aids digestion and helps keep your dog feeling full. Whole wheat flour contains B vitamins, crucial for metabolism, and minerals like iron and magnesium.

Storage and Serving Tips

• Store these homemade sardine crackers in an airtight container in the refrigerator.
• They will stay fresh for up to 7 days.
• For longer storage, you can freeze them for up to 2 months.
• To thaw, just let them sit at room temperature for an hour or two.
• Serve them at room temperature as a tasty reward.
• You can break them into smaller pieces for training treats.
• They’re great on their own, or as a crunchy topper for their regular kibble.

Common Questions & Troubleshooting

Can I use sardines in oil?

Yes, but make sure it’s olive oil or another dog-safe oil. Drain the oil thoroughly before mashing the sardines. Water-packed is usually preferred to control fat intake.

My dough is too sticky, what should I do?

Just add a little more whole wheat flour, a tablespoon at a time, until the dough is firm and easy to handle.

My treats aren’t crispy enough.

After baking, leave them in the oven as it cools down for an extra 15-20 minutes. This really helps to dry them out and get them crispy.

Can puppies eat these treats?

Yes, but in moderation. Break them into smaller pieces. Always introduce new foods slowly to avoid upsetting their stomach.

Wrapping Up

Making these sardine and flour crackers is super simple. They’re a healthy, delicious way to show your dog some love without all the mystery ingredients. Your pup will adore these savory, crunchy treats, and you’ll feel good knowing exactly what they’re eating.
