Gizzards are the internal organs of fowl, such as turkey and chicken. Unlike the liver, the gizzard is harder and cooks up for a nice firm treat for dogs. While there are several ways to prepare a gizzard treat, boiling them makes the treat healthy by avoiding added oils and fat used for frying or baking.
Wash the turkey gizzards with cool water.
Place the gizzards in a medium pot and add water. Fill the pot with water until the gizzards are covered by about 3 inches. Add sage or ginger to the water for flavor, if desired.
Boil the water on medium-high heat. When it reaches boiling, turn down the heat to low and allow the gizzards to simmer for approximately 30 minutes or until they are tender.
Set the pot off of the heat and allow the gizzards to cool. Pour the gizzards in a colander and drain the water. Chop or grind them into small pieces.
Mix the gizzards with 1/2 cup of peanut butter, 1 large egg and 1 cup of oat flour in a large mixing bowl. Add 1 cup of brown rice flour to the mixture.
Pour the mixture on a large piece of parchment or wax paper and fold the paper over. Press it firmly and flatten the mixture out to approximately 1 inch.
Cut cookie-sized treats from the dough. Place them on a cookie sheet and bake at 350 degrees for approximately 20 minutes or until golden brown.
