Yesterday I was out of Raptor's snacks so I created these. To date they are one of only two biscuits she will eat. Such a fussy old gal. I made the oat milk in the first link only I now made a recipe and a half. The nine cups water and 1 1/2 cups raw oats will create just enough pulp to make these delectable Doggie biscuits.
Mix the egg, oat milk pulp, garlic powder, gravy master, and beef base together until fully incorporated and add flour and mix well. spread out onto a well sprayed cookie sheet and bake at 325 for 4o minutes. Then cut into individual biscuits and put back into the oven until hard as rocks (another 20-40 minutes).
