Making homemade dog biscuits and cookies can be a great way to treat your pup without spending a fortune or specialty treats. It also lets you limit his intake of preservatives, artificial dyes and flavorings found in some commercial dog treats. Examine the ingredients found in any all-natural, high-end dog cookies and you'll find you have many of those same ingredients in your home. So start baking and use these as gifts for friends' dogs or dogs at a local shelter.
Combine olive oil and mashed sweet potato in a mixing bowl and stir vigorously. Thorough mixing will prevent small pockets of sweet potatoes from forming inside the batter, which can make the cookie fall apart more easily after cooking. Add in the almond flour and mix the wet and dry ingredients thoroughly, again. Many dogs are sensitive or allergic to wheat and corn; by using almond flour, you give your dog cookies a grainlike texture without any of the digestive upset that can occur with wheat.
Spray a nonstick spray over the entire sheet, or grease the sheet with the wrapper from a stick of butter, before baking the cookies. Place one teaspoon of batter at a time on the cookie sheet so the cookies are spaced 4 inches apart. Flatten the cookies with a fork, your hand or the spoon after arranging them on the sheet. Unlike human cookies, which contain lots of butter, these dog cookies won't melt flat during baking, so you have to flatten them before baking.
Preheat the oven to 350 degrees Fahrenheit and bake the cookies for 30 minutes. Use a spatula to remove the cookies from the tray and let them cool on a cooling rack or plate. Wait at least 15 minutes for them to cool before serving one to your pup. When the cookies are cooled, store the remaining ones in plastic wrap or a hard plastic container.
