Here's an easy, safe, natural and healthy treat that dogs drool over! Makes their breath smelling fresh too-- what more can a pawrent ask for? I found this recipe somewhere on the web and altered it a bit to make it more natural and healthier for our furry friends. The original recipe called for 5 cups of flour and regular powdered milk. I instead used non-fat powdered milk and used just 2 3/4 Unbleached flour and 2 1/2 cups oat flour. You can make your own oat flour by grinding oatmeal using a food processor or even a coffee grinder would do. I or should I say, my dog Coco gave them as gifts to her doggy friends this Christmas. They were well received and consumed in no time... by the dogs and their humans too! We have lots of doggy friends and this recipe yields a lot so this was VERY economical.
