Ingredients You’ll Need
This recipe requires only three dog-safe, nutrient-dense ingredients.

How to Make 3-Ingredient Sardine and Oat Dog Treats
Step 1: Prepare the Sardines
Drain the sardines and place them in a mixing bowl.
Use a fork to mash them into small pieces.
This makes it easier to blend with the oats and egg.
Step 2: Add the Egg
Crack the egg into the bowl and mix thoroughly.
This helps bind the ingredients and adds protein.
Step 3: Add the Oats
Stir in the rolled oats or oat flour until a dough forms.
Tips:
- If too sticky: add more oat flour
- If too dry: add a spoon of water or mash another sardine
Aim for a thick, moldable dough.
Step 4: Shape the Treats
You can shape them in different ways:
- Roll into balls and flatten
- Press into silicone treat molds
- Roll out and cut with cookie cutters
Small bite-sized treats work great for training.
Step 5: Bake the Treats
Place your treats on a parchment-lined baking sheet.
Bake at 350°F (175°C) for 15–25 minutes, depending on size and desired crispiness.
- Shorter bake = softer treats
- Longer bake = crunchier treats
Let cool completely before serving.
Storage Instructions
Refrigerator:

These treats freeze very well thanks to the moisture from the sardines.
