I have all 7 of my bulldogs on natural balance venison and sweet potato and all are doing good on it but I just found out today that one of my bulldogs has a heart condition and needs to be on a low sodium diet which is around 0.25% sodium. Does anyone know of a dry dog food (would prefer a grain free food) that is low in sodium. I have emailed natural balance to see how much sodium is in their food but I figured I would ask here to see if any of you know of a good food. I was looking at the royal canin cardiac prescription diet but I had seen that last year they had recalled it so I would rather not put her on that food. I have been looking at different foods but on all of their websites the sodium content is not on there.
