1. Preheat your Oven:
   Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Combine the Wet Ingredients:
   In a mixing bowl, combine the pumpkin purée, egg, and ground flaxseed. Stir until smooth.
3. Add the Dry Ingredients:
   Gradually add the oat flour to the mixture, stirring until a firm dough forms. If the dough is too dry, add water one tablespoon at a time until it’s workable but not sticky.
4. Shape the Dental Sticks:
   Roll the dough into thin, stick-like shapes about 4-5 inches long and 1/2 inch thick. You can also flatten the sticks slightly for easier chewing.
5. Bake:
   Place the sticks on the prepared baking sheet and bake for 25-30 minutes, or until firm and golden. For extra crunch, leave the sticks in the oven with the heat turned off for an additional 10 minutes.
6. Cool Completely:
   Allow the dental sticks to cool fully before serving them to your dog.

Storage
