Tuna Dog Treats

Preheat the oven to 180 °C and line a baking sheet with parchment paper.

Drain the tuna, place it in a bowl, and mash with a fork. Add the egg, 3 tablespoons of water, and mix. Stir in the oat flakes, flour, and knead into a smooth dough.

Form about 40 small balls and spread them on the baking sheet. Bake for 25 to 30 minutes until golden brown.
