Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
In a mixing bowl, combine the flour, pumpkin, peanut butter, and eggs. Stir until the mixture comes together.
Roll out the dough on a lightly floured surface to about ¼-inch thickness. Use a cookie cutter to cut out shapes and place them on the prepared baking sheet.
Bake for about 40 minutes or until the treats are hard and dry.
Let the treats cool completely before serving them to your dog.
