It can be really difficult to find the sodium content of pet foods without scouring the brand’s website or emailing them directly. Once you have a list of potential foods, you should run those foods (and the sodium content they contain) past your vet for his or her approval.
Generally speaking, most veterinarians use the following categories when discussing low-sodium diets (it usually easier to use the amount of sodium provided for each 100k calories as your unit of measure when comparing foods). Ask your vet which level of sodium restriction your dog requires::
• Dogs who require mild sodium restriction should be offered foods with between 0.35% and 0.5% sodium content (80 to 100mg/100kCal)
• Dogs who require moderate sodium restriction should only receive foods with between 0.1% and 0.35% sodium content (50 to 80mg/100kCal)
• Dogs who require severe sodium restriction should be offered food with less than 0.1% sodium content (<50mg/100kCal)
The following websites have a lot of info on many brands of dog food, and the sodium levels they contain:

One way that you can restrict the sodium levels in your pal’s diet is by making his food at home. Whether you use homemade ingredients exclusively or add items to a commercial brand to balance out the nutrients, talk with your veterinarian about your plans.

Lastly, ask your vet about using an Omega-3 fatty acid supplement. The omega-3 fatty acids EPA and DHA may help to stabilize heart muscle cells. Your veterinarian can help you to choose an omega-3 fatty acids supplement with good bioavailability, meaning that it is easily absorbed by the body, and tell you the correct dose to use.
Best of luck to you and your dog!
