Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.

Mash the banana in a mixing bowl until mostly smooth.

Add the peanut butter and stir until well combined.

Gradually add the oat flour and mix until a firm dough begins to form.

Add the water one tablespoon at a time until the dough is soft but easy to handle.

Place the dough on a lightly floured surface and roll it to about 1/4 inch thick.

Cut the dough into narrow strips or small chew stick shapes appropriate for your dog.

Arrange the sticks on the prepared baking sheet.

Bake for approximately 20 to 25 minutes, or until firm and lightly golden.

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

Use natural peanut butter with no xylitol. Check the label carefully before using it.

These homemade sticks are baked treats, not indestructible dental chews. Always supervise your dog while eating them and choose a size appropriate for your dog's chewing ability.

Store completely cooled treats in an airtight container in the refrigerator and use within a few days. Freeze extras for longer storage.

These are treats and should be served in moderation alongside your dog's regular complete and balanced food.
