We previously made these cookies and offered them for sale online as well as our brick-and-mortar store. People, as well as their beloved dogs, absolutely loved them. One of the best things about these homemade dog treats is that by following the directions below, they will have a much longer shelf life than most "homemade" dog treats. As a matter of fact, we never had even one cookie go bad. Of course, that could also be owed to the fact that they sold as fast as we could make them! But honestly, they will last for a month, or more, if you get them dried out completely.
