Preheat the oven to 350°F and line a baking sheet with parchment paper.

Add the whole wheat flour and rolled oats to a large mixing bowl.

Add the beaten egg and olive oil if using.

Gradually pour in the chicken broth while mixing until a firm dough forms.

Transfer the dough to a lightly floured surface and knead it gently until it comes together.

Roll the dough to approximately 1/4 inch thick.

Use a cookie cutter to cut the dough into small biscuits and place them on the prepared baking sheet.

Bake for about 25 minutes, or until the biscuits are firm and lightly golden around the edges.

Remove from the oven and allow the biscuits to cool completely before serving.

Use homemade or store bought chicken broth that is low sodium and completely free from onion, garlic, and seasoning blends.

Never use broth containing onion or garlic because these ingredients are unsafe for dogs.

For smaller dogs, use a small cookie cutter and adjust portions accordingly.

For a crunchier biscuit, allow the cooled treats to sit in the turned off oven for several additional minutes after baking.

Store completely cooled biscuits in an airtight container in the refrigerator. Freeze extras for longer storage.

These biscuits are intended as an occasional treat and should not replace your dog's complete and balanced food.
