The food you are feeding may not have ADDED salt but it will definitly have ingredients in it that have salt in them. Every living thing needs salt to live. It is in every cell of our and our dogs body. Salt is absolutely an essantial ingredient. The problem is when there is too much salt, just like too much salt is a problem for people. Dog foods are not required to divulge their sodium levels, so I imagine that there are qite a few that have high levels, because it is a cheap flavor enhancer.
