Dogs can eat sweet potatoes, which are an excellent source of vitamin B6, vitamin C, manganese, beta carotene and fiber. The antioxidants in sweet potatoes contain promote healing, help combat the effects of aging and help prevent cancer.
Bake whole sweet potatoes in an oven or a microwave before serving for canine consumption. Alternatively, slice the sweet potatoes thinly, spread in a single layer on a cookie sheet and bake for about three hours in an oven preheated to 250 degrees Fahrenheit. The longer the sweet potatoes bake, the crunchier they become. The slices can also be placed in a dehydrator for similar results. Sweet potatoes provide an all natural, healthy and cost-effective treat for dogs.
