Sourdough Doggie Biscuits

Directions

1. 1
   Combine the first 5 ingredients with an electric mixer.
2. 2
   Add the oats and as much of the flour as you can until the dough is too hard to mix.
3. 3
   Turn dough out onto a floured surface and knead in the remaining flour.
4. 4
   Dough should be stiff, but not crumbly.
5. 5
   Roll out dough about 1/2-inch thick and cut into desired shapes with cookie cutters, or for a quicker version just cut 1/2-inch wide strips with a pizza cutter or knife, and then cut strips to 2-inch lengths.
6. 6
   Place on ungreased cookie sheets and bake at 325°F for 20 minutes.
7. 7
   Turn biscuits over and bake another 20 minutes.
8. 8
   Turn off oven and open door so it's ajar to let out excess heat for a few minutes and then close door and leave biscuits in oven until all the heat is gone.
9. 9
   If there is still moisture in the biscuits, let them air-dry until they are completely hard and crisp before storing.
