Why Blueberries Are Great for Dogs
Blueberries are often called a superfood and for good reason. When fed in moderation, they offer several benefits for dogs.
Benefits of Blueberries for Dogs
- Rich in antioxidants that support immune health
- Help reduce inflammation
- Support brain health, especially in senior dogs
- Low in calories and naturally sweet
Because blueberries are soft and easy to mash, they work beautifully in baked dog treats.
Why Oats Are an Excellent Biscuit Base
Oats are one of the most dog-friendly grains you can use, especially for homemade treats.
Benefits of Oats for Dogs
- Easy to digest
- High in fiber for gut health
- Gentle alternative to wheat
- Provide slow, steady energy
Together, blueberries and oats create a biscuit that’s both nutritious and satisfying without being heavy.
Why Homemade Blueberry Oat Biscuits Are Better
Many store-bought blueberry dog treats rely on artificial flavoring rather than real fruit. Baking at home ensures your dog gets the real thing.
Homemade biscuits allow you to:
- Use real blueberries instead of flavoring
- Avoid sugar, syrups, and preservatives
- Adjust crunch level for puppies or seniors
- Control portion size easily
Plus, there’s something special about baking treats just for your dog.

Step 2: Prepare the Blueberries
Place the blueberries in a small bowl and gently mash them with a fork. You want them broken down but not fully puréed—small chunks are perfect.
Step 3: Prepare the Oats
Place rolled oats into a blender or food processor and pulse until they form a coarse oat flour. Leaving a little texture helps create crunchy biscuits.
Step 4: Mix the Dough
In a large bowl, combine:
- Mashed blueberries
- Applesauce
- Egg
- Ground oats
- Flour
Mix until a thick dough forms. Add water one tablespoon at a time if the dough feels too dry. The dough should be firm but easy to roll.

Step 5: Roll and Cut the Biscuits
Lightly flour your work surface. Roll the dough out to about ¼-inch thickness.
Use dog-bone cookie cutters or cut into simple squares or rectangles. Place biscuits onto the prepared baking tray with a little space between each.
Step 6: Bake Until Crunchy
Bake for 25–30 minutes, or until the biscuits are firm and lightly golden around the edges.
For extra crunch, turn off the oven and leave the biscuits inside for an additional 10–15 minutes with the door slightly open.

Never serve warm biscuits to your dog.
