As you read through the ingredient list on a typical box of store-bought dog treats, you may find yourself baffled by the long list of chemicals and fillers. Among these fillers are often corn and wheat meal, corn germ, corn syrup and "wheat middlings," all of which have little to no nutritional value and are not a part of a dog's natural diet. Whether your dog is allergic to these ingredients or you just want to provide a natural option with no additives, making your own corn- and wheat-free treats is a great alternative.
Preheat your oven to 400 degrees Fahrenheit.
Cut the raw liver into approximately 1-inch squares with a sharp knife.
Place all of the ingredients except for the broth into a food processor or blender. Pulse to combine.
Add in the broth a tablespoon at a time as you continue to pulse your food processor. Watch the mixture carefully as you do this; the mixture should look like a thick dough and should be just spreadable.
Grease a 13-by-9 pan using a small amount of vegetable shortening or animal fat.
Pour or scoop the mixture into the greased pan and bake in the oven for 25 minutes, or until the mixture has turned from pink to slightly brown.
Allow to cool on a wire rack for approximately five minutes.
Loosen the baked mixture with a knife around the edge of the pan and invert onto the wire cooling rack.
Allow to cool completely and then cut into square treats approximately 1 inch in size, or smaller depending on the size of your dog.
Refrigerate the treats for up to two to three weeks or freeze for up to two months.
