Peanut Butter Pumpkiny dog treats

I've made dog treats with chicken or beef broth and shredded cheese, but this is my first attempt at dog treats on the sweeter side. If you want enough to give as gifts or if you have several dogs I suggest doubling this recipe. The dogs like them except my little pom., but she's a food snob, so she doesn't count.

2 1/2 cups whole wheat flour

2 eggs

1  cup canned pumpkin

3 tablespoons peanut butter

1/2 teaspoon salt

1/2 teaspoon ground cinnamon

3/4c rolled oats

Directions

1. Preheat oven to 350 degrees F (175 degrees C).
2. Whisk together the flour, eggs, pumpkin, peanut butter, salt, and cinnamon in a bowl. Add water as needed to help make the dough workable, but the dough should be dry and stiff. Roll the dough into a 1/2-inch-thick roll. Cut into 1/2-inch pieces.
3. Bake in preheated oven until hard, about 35 minutes.
