That's the one I use, as well. If you don't have a Kroger (or affiliated store) in your area, look for Laura Scudder brand.Kroger has a natural peanut butter that isn't really any more expensive than the basic brand names. I buy it for myself and the dogs get a bit.
Given the amount they eat, I wouldn't care about added sugar. The important thing is NO artificial sweeteners, a few brands have xylitol which is deadly to dogs.
