Preheat the oven to 350 F.
In a large bowl, mix together eggs, cinnamon, pumpkin, flour, salt and peanut butter. This mixture will become stiff, dry and crumbly really quickly when first mixing.
Add a little bit of water to help moisten the ingredients, then you will be able to work and knead the dough. Only add a tablespoon or so as you go. You want the dough to end up being a dry and thick consistency.
Flour your countertop and roll the dough out to be about a ½ inch thick. Use your cookie cutters to cut out individual treats and place on a greased baking sheet. You don’t need to separate them a ton, they don’t rise much.
You will have left over dough after cutting out the first batch of treats. Quickly knead and roll out the dough left over dough to make even more!
Bake for about 35 minutes or until hard. Serve to your fur-baby! They will be living their best doggy life!
