My dog loves these, and I loved the idea of these being all natural, believing the only ingredient was duck. With no ingredient list provided (and none readily available through Google search), it does leave the consumer having to trust that what they are purchasing is the best for their dog. So imagine my disappointment to see cane sugar listed as one of the ingredients - the 4th to be exact. My dog doesn't need added sugar in her diet. I will give these a pass in the future, and seek out something that contains only ingredients my dog should be eating.
