Dog Food Sodium Calculator
Calculate the sodium content of your dog's food on a dry matter basis and assess daily sodium intake — important for dogs with heart or kidney disease.
What Is the Dog Food Sodium Calculator?
Calculate the sodium content of your dog's food on a dry matter basis and assess daily sodium intake — important for dogs with heart or kidney disease.
Sodium restriction is a key dietary intervention for dogs with congestive heart failure, hypertension, and chronic kidney disease. But comparing sodium levels between foods is confusing — wet and dry foods need to be evaluated on a dry matter basis, and daily intake depends on how much the dog eats. This calculator does both.
Every result is based on published veterinary research and breed-size-specific growth data — not generic averages. This tool is completely free, works instantly in your browser, and requires no account or sign-up.

How It Works
Sodium content is expressed as a percentage on the guaranteed analysis or as mg per 100g. Converting to dry matter basis and then to daily mg intake allows accurate assessment of whether a dog's sodium consumption meets veterinary guidelines. For dogs with heart disease, the ACVIM recommends sodium restriction in later stages (B2 and C): mild restriction at 80–100mg/100kcal, moderate restriction at 50mg/100kcal.
