Sweet potato chews
I was in B&B Petstop talking to the Natural Balance Rep and she told me about these. They're expensive for the amount you get.
She also told me that you can take the Natural Balance Fish and Sweet Potato Allergy Formula canned dog food and spread it on a cookie sheet and dry it in the oven to make chews for the dogs.
As for the plain sweetpotato chews, I cook the yams in the microwave, mash them up with a little water and olive oil and spread on a cookie sheet , bake at 350 for about an hour just to get them good and hot and start the drying process. Then I turn the oven down and let them continue to dry.
