Bullwrinkle has an extensive listing of dog treat recipes like this one for Liver Brownies.
Liquefy livers in food processor, pour into mixing bowl and add other ingredients. Mix until smooth like a brownie batter. Spread on a cookie sheet (1/2 sheet cake size) (I use parchment paper to line the pan) until it’s evenly spread about 1/3 inch thick. Bake at 350 F for about 35 minutes. When cool cut into squares, or whatever shapes you prefer. I keep them in a zipper bag in the refrigerator.
The Poop Pantry (Love the name!) offers this reader-submitted recipe for Tempting Training Treats.
Combine all ingredients in a large bowl; mix well. Roll the dough out to the size of a cookie sheet; Pat the dough onto a lightly greased cookie sheet, bringing it to the edges. Using a sharp knife or a pizza cutter, cut desired sizes into dough (just score through). If you're using as training treats, cut them into small pieces; Sprinkle a little extra cheese on dough for flavor, if desired. Bake in a 350 degree oven about 15 minutes until golden brown. Turn off the oven and let cool for a few hours; They will keep hardening the longer you leave them. Break them apart; store tightly covered or in the freezer. From Laura Ann DeLongo, Maryland
There are dozens of other sites where you can find free recipes, but no matter which site you choose, be sure to review the recipes for the presence of foods that can be toxic to dogs such as garlic, onions, and chocolate. The recipes may need slight modification, as I have done above, to make sure you are not putting your dog at risk.
Read this article on food safety before you begin making homemade food or treats for your dog. Gourmet Sleuth also has some good articles detailing ingredients which may be toxic. Once you have done your research, be prepared to put on your apron and dig in!
