Why You Will Love This Recipe

There’s something so satisfying about making homemade treats for your dog. You know exactly what goes in them, and it feels great to give your pup something that’s both tasty and wholesome. Here are just a few reasons you’ll love making these mackerel treats:

Wholesome ingredients – Only four real ingredients. There are no preservatives, no weird additives, and no mystery stuff like in most store-bought treats.

Easy to make – Just mix, roll, cut, and bake. It’s like making cookies! No fancy tools or complicated steps.

Simple to customize – You can easily swap out ingredients to suit your dog’s preferences or dietary needs.

High value – These treats have a strong scent and flavor that make them perfect as high-reward training treats.

Economical – Much more budget-friendly than many store-bought dog treats, and you get to control the quality.

Ingredients and What They Bring to the Treats

These treats are made with real food that’s good for your dog. Here’s a quick look at what each ingredient adds:

  • Mackerel in olive oil – Packed with protein and omega-3 fatty acids, which support your dog’s skin, coat, and overall health.
  • Unsweetened applesauce – Adds moisture and a touch of sweetness, plus fiber and vitamins.
  • Egg – Helps bind the dough together and adds protein and nutrients.
  • Oat flour – A gluten-free flour option that’s easy on your dog’s digestion.

Ingredient Notes and Substitutions

When making these treats, there are some things to keep in mind and simple swaps you can make:

  • Mackerel – Do not use mackerel in brine, as it contains too much salt. You can use fresh cooked mackerel for a lower-fat option.
  • Fish substitutes – Try sardines or anchovies packed in water for a similar fishy flavor and nutritional boost.
  • Applesauce – Swap with mashed banana, plain pumpkin puree, or plain mashed sweet potato if needed.
  • Oat flour – Make your own by blending old-fashioned rolled oats until finely ground. One cup of oats yields about ¾ cup of flour.
  • Flour substitutes – Use white or brown rice flour (you can make it by blending uncooked rice). All-purpose flour or a 50/50 mix of all-purpose and whole wheat flour can also be used. Avoid using only whole wheat flour because it’s too dense on its own.

Equipment Needed

You likely have the kitchen items you need for making the treats. You can use any cookie cutter, but bone-shaped cookie cutters make them extra cute.

How to Make Mackerel Dog Treats

You’ll be surprised how quickly and easily these come together. Let’s get baking!

  1. Preheat your oven to 350°F and line a baking sheet with parchment paper or a silicone baking mat.
  2. Open the tins of mackerel and drain the olive oil. Place the mackerel in a bowl and flake it into small pieces with a fork.
  3. Add the applesauce and egg to the bowl and mix until well combined.
  4. Stir in the flour until a dough forms.
  5. Roll the dough out on parchment paper to about ¼” to ½” thick.
  6. Use a cookie cutter to cut out treats and place them on the prepared baking sheet.
  7. Bake for 15-18 minutes or until lightly golden on the bottom.
  8. Let them cool completely before giving one to your pup.

Tip: Want to make training treats? Instead of using cookie cutters, use a knife or pizza wheel to cut the dough into small squares before baking.

How to Store the Treats and How Long They Last

Keep the treats in an airtight container in the refrigerator. They’ll stay fresh for up to 1 week.

For longer storage, freeze them in a freezer-safe container or bag. They’ll keep for up to 3 months. Just thaw them in the fridge overnight when you’re ready to use them.

Can people eat these treats?

Yes, they’re safe for humans to eat. If you enjoy mackerel, go ahead and try one. Just know your pup might give you the stink eye for stealing their snack!
