Preheat oven to 350°F (176°C).

Add oats to the bowl of a food processor. Let machine run for 2 - 3 minutes, until oats are almost flour consistency with a few big pieces left.

Add eggs, banana, blueberries and flour to the food processor and pulse 10 - 15 times to break everything up and get it incorporated into the dough.

Let the machine run for 30 - 60 seconds until the dough is uniform, then turn off and remove bowl.

Scoop with small cookie scoop and drop on a parchment (or silpat)-lined sheet pan.

Flatten tops with wet fingers to form a circle.

Bake for 18 - 20 minutes, rotating halfway through.

Cool completely before giving to your dog.
