Ingredients and What They Bring to the Treats

This recipe uses just a handful of everyday ingredients, each one playing an important role in creating soft, flavorful treats your dog will love.

  • Tuna in water – Adds a bold fish flavor and protein that dogs find irresistible.
  • Eggs – Help bind everything together while adding protein and structure.
  • Coconut oil – Adds moisture and a boost of healthy fats that support skin and coat health.
  • Oat flour – Creates a soft, chewy texture and is easy on most dogs’ stomachs.

Ingredient Notes and Substitutions

A few simple tips and swaps can help you customize this recipe or work with what you have on hand.

  • Using no salt or low-sodium tuna is best.
  • You can make oat flour by blending old-fashioned rolled oats in a blender or food processor until a flour consistency is reached. One cup of oats makes about 3/4 cup of flour.
  • You can substitute oat flour with brown rice flour and make it by blending uncooked brown rice.
  • You can substitute oat flour with all-purpose flour or a 50-50 combination of all-purpose and whole wheat flour. Because whole wheat flour is denser, it’s not a good substitute to use by itself.
  • Note: Flour substitutes may affect the dough. Start with less and add as needed.

How to Make Tuna Fudge for Dogs

These tuna fudge dog treats come together quickly, making them great for busy days or last-minute treat prep. Here’s what to do:

  1. Preheat the oven to 350°F. Line a baking sheet with parchment paper, letting the edges overlap for easy lifting later.
  2. Place all ingredients into a food processor or blender and blend until combined and smooth.
  3. Transfer the dough to the prepared baking sheet and spread it evenly to about 1/3-inch thick.
  4. Bake for 23-26 minutes, until set.
  5. Let the fudge cool completely. Use the parchment paper to lift it off the baking sheet and transfer it to a cutting board.
  6. Cut into 1/2-inch squares and serve or store.

Can people eat these treats?
