I wouldn’t say chicken is naturally high in sodium. A lot of meats have added salt sure, so that is something to look out for. But just by looking at the Mg of sodium per serving you can easily pick out which ones have salt added.
I used to homecook for my past dog with cardiac issues with the go ahead from my vet. The food was where it needed to be in sodium, regardless of the type of protein I used (beef, chicken, goat, venison). Use common sense when buying meat for the dogs and pass it by your vet.
