Doggie Biscuits

1 1/2 cups whole wheat flour
1/2 cup all purpose flour
1/2 cup cornmeal
1/2 cup oats
1 1/2 cups water, or as needed
1/2 cup canola oil
2 eggs
3 Tbsp peanut butter
2 Tbsp vanilla

Preheat oven to 400.  Grease cookie sheets.  Mix together whole wheat flour, all purpose flour, cornmeal, and oats.  Make a well in center of dry ingredients and gradually pour in water, oil, eggs, peanut butter, and vanilla.  Mix well.  If dough is too wet, add a small additional amount of whole wheat flour.  On a flat surface, use a rolling pin to roll out dough to 1/4 inch thickness.  Cut dough into dog biscuit shapes with cookie cutter.  Place biscuits on prepared cookie sheet.  Bake cookies for 15-20 minutes.  Turn off oven and leave biscuits inside for another 20 minutes to harden.
