Preheat your oven to 350 degrees and line a baking sheet or cookie sheet with a slipmat or parchment paper.

Combine the pumpkin puree, peanut butter, and eggs in a medium-large bowl and mix until combined. In a smaller bowl, combine the oat flour and ground cinnamon and stir to combine.

Slowly add the dry ingredients to the peanut butter/pumpkin mixture and stir until the dough is thick and dry. If the dough is too sticky, add a bit more oat flour until it easily comes together and is easy to manage.

On a floured surface, roll out the dough to a ½ inch thickness and use cookie cutters to cut out the treats.

Bake treats for around 30-40 minutes (depending on how crisp your dog likes them!), then remove them from the oven and allow them to cool for 5-10 minutes before transferring to a baking rack to cool completely.

These treats are best stored in an air-tight container in the refrigerator for about a week, or for about 3 months in the freezer.
