Hi Rick

NRC reports ” the SUL [safe upper limit] of Na for dogs can be reasonably set at approximately 15 g Na.kg-1 diet DM basis.” This means 15 grams of sodium for every kilogram of diet on a dry matter basis of 4000kcal/kg, equivalent to ~3.5 grams sodium/1000kcals

I agree with Gerald in that you’ll often need to call the company and ask them for the sodium level in the diet you are interested in. Some companies do post this information on line.
