Hi Chad, and “Anonymously”,

The prescription low sodium food you can get from your vet is great, if your dog will eat it. Also, there are different degrees of sodium allowable for the canine cardio patient. Some just need reduced or moderate levels of sodium, while others need a food with drastically lower levels. Dogs need some sodium in their diets. So you should find out from your vet what kind of sodium restrictions your dog needs, especially if your dog has other health issues, such as kidney or liver disease.

These are all on a dry matter basis:
Mild Sodium restriction is 0.3 -0.4%
Moderate Sodium restriction is 0.2 -0.3%
Marked Sodium restriction is 0.15-0.2%
Extreme Sodium restriction is 0.75-0.15%

My personal problem with the Hill’s Prescription Heart Care canned food is, the fat content is at 29.0%, and the protein content is 17.3%. Dogs with a heart problem need higher and high quality protein in their diets, and lower fat. It also contains corn (not a problem unless your dog has a corn intolerance), but I know it’s a cheap filler and it’s listed as the third ingredient!
With the Royal Canin Veterinary Diet Early Cardiac diet, the first ingredient is rice followed by chicken fat. Powdered cellulose (saw dust) is amongst the first six ingredients. I just know I can feed my dog a whole lot better than this.

It’s been determined that inadequate protein intake, or deficiencies of specific amino acids, can actually cause serious heart disease and the Cardiology Subspecialty of the ACVIM has recommended avoidance of protein restricted diets (specifically for dogs with old-age heart valve disease). Also, it’s extremely important for cardiac patients to maintain a normal body weight. Excessive weight, in the form of body fat, places additional stress on the heart and in more than one way. Besides the additional work of the heart that’s required for normal ambulation and exercise, excess fat causes an “oxidative stress”. Oxidative stress disrupts normal metabolism in many ways and impairs the ability of blood vessels to expand and deliver nutrients in a normal way.

I’ve persisted and found these additional low sodium dog foods, that are very high in quality:

• Evanger’s Beef with Spinach and Kale Canned dog food – 0.1136% sodium on a dry matter basis

• Solid Gold Howling at the Stars turkey, Ocean whitefish, and Sweet Potato Recipe (canned) 0.23% sodium

• Solid Gold Hund-N-Flocken With Lamb (dry) – 0.23% sodium

Here is where you can see charts in both allowable sodium in milligrams per kcal per 100, and also by percentages of dry matter. With this information you can contact dog food manufacturers and get the sodium content. If you scroll down further (at the link below) it has a list of some over the counter dog foods that are low sodium.
I’ll say it again…. it’s SO wrong that sodium levels aren’t published on the dog food packages, but I’m willing to jump through hoops to get my dog the food he needs!
