Orange-fleshed sweet potatoes -- often referred to as yams in the United States despite the fact that the two plants are not related botanically and are not in the same family, according to the Library of Congress -- are packed with fiber and healthy starches, are completely gluten-free, and are low on the glycemic index. In addition to high fiber content, sweet potatoes provide plenty of beta-carotene and vitamin C, which can add a healthy boost to your dog's diet.
Consult with your veterinarian about the amount of fiber and natural sugars that should be included in your dog's diet. Different sized dogs have different nutritional requirements; what is an appropriate amount of fiber for one dog may be too much for another.
Preheat your oven to 350 degrees Fahrenheit. Line your baking sheet with parchment paper and set aside.
Place your cubed sweet potatoes into a mixing bowl and cover with a damp paper towel. Microwave on high for approximately two minutes or until the sweet potato chunks are cooked through and soft.
Mash the cooked sweet potatoes, using a fork or a potato masher.
Add your honey and applesauce to the mashed potatoes. Combine and slowly add a beaten egg. Mix these ingredients together thoroughly.
Add a quarter-cup of the potato or rice flour at a time, incorporating it completely before adding the next quarter. Mix together thoroughly until the mixture forms a slightly sticky dough.
Use clean hands to roll the dough into balls and place them on the cookie sheet. Use your veterinarian's recommendations about the appropriate servings of fiber and sugars to determine how large to make the cookies.
Bake the sweet potato cookies for approximately 20 minutes.
Remove the cookies from the oven and allow them to completely cool before giving them to your dog. Only provide your dog with the amount specified by your veterinarian.
