Like so many other components of a dog’s diet, sodium is essential for life, yet toxic in excessive quantities. But fortunately, sodium is generally not a mineral most dog owners need to worry about.
Domestic dogs typically ingest more than enough sodium to meet their biological needs, and they have several physiological mechanisms for excreting excessive amounts of sodium (such as increased urination and water consumption), should they consume too much.
However, in some cases, dogs will need a specific low sodium diet.
Warning: There is a lot of misleading information on the web regarding the sodium content of various dog foods, but we have confirmed the sodium content of all the foods listed below with the manufacturers. However, we have NOT yet confirmed the sodium content of the treats discussed below. Always remember to double-check the nutritional information on the product packaging and consult with your vet if you’re unclear about anything.

Health Problems that Require Low-Sodium Foods
High salt intake can cause many people to develop high blood pressure, but this rarely appears to happen to dogs. In fact, a 2008 study, published in Topics in Companion Animal Medicine, found that dogs adapt well to a wide range of sodium levels. The author of the study states that:
“There is no strong evidence that increased dietary sodium increases the risk of hypertension in dogs and cats, and the current recommendation for hypertensive animals is to avoid high dietary salt intake without making a specific effort to restrict it.”
As you can see, you probably don’t need to worry about your pup developing high blood pressure unless you supplement his diet regularly with Doritos and pickled eggs. But high blood pressure isn’t even the reason most dogs end up needing a low-sodium diet.
Most dogs that require a low-sodium diet suffer from congestive heart failure (some liver or kidney issues can also lead your veterinarian to recommend restricting his salt intake). Congestive heart failure causes fluid to build up in the body, and salt exacerbates this phenomenon.
By reducing the level of sodium in your dog’s food, you can help your dog shed some of this excess fluid in his urine. This will help take some strain off of his internal organs, and generally bolster his health.
Recommended Sodium Levels for Canines
Various dog foods have wildly different sodium levels. Unfortunately, it is actually somewhat difficult to find the sodium levels of many dog foods, as manufacturers aren’t required to print such information on the labels. In fact, the AAFCO doesn’t even establish a maximum acceptable level for sodium content – it only establishes a minimally acceptable value.
However, with sufficient homework, you can usually find the sodium content of commercial foods. This can allow you to select a food that fits within the range prescribed by your vet.
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):
- Dogs with no sodium restrictions require food with at least 0.5% sodium content (>100mg sodium/100kCal)
- 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)
While the AAFCO doesn’t address the maximum amount of sodium dogs can ingest safely, the National Research Council of the National Academies does.
According to their guidelines, a 33-pound dog who burns about 1,000 Calories per day should not consume more than 2,000 milligrams per day. They do not explicitly state how to extrapolate this figure, as calorie consumption and body weight do not necessarily have a linear relationship.
Salt Toxicity Is Serious Problem For Dogs
For the most part, a dog food’s sodium content is only a long-term concern of those dogs with certain medical conditions.
But sodium can be immediately dangerous – a condition called salt toxicity — to any dog who consumes a significant quantity in a short period of time, such as if Fido gets into the spice cabinet or pantry and goes to town on a shaker.
Salt toxicity isn’t just a problem for dogs, as numerous other species are susceptible (pigs only tolerate a small amount of salt in a short amount of time, while sheep can tolerate quite a bit).
The lethal dose for dogs is somewhere in the neighborhood of 4 grams per kilogram of body weight. As a point of reference, a teaspoon of salt weighs about 5 grams and a kilogram is equal to about 2.2 pounds.
Dogs who consume significant amounts of salt may vomit, or suffer from muscle tremors or seizures. But this kind of toxicity is somewhat rare in dogs, and tends to occur via accidental ingestion of very salty food.
Contact your vet immediately if your dog exhibits signs of salt toxicity – this isn’t a long-term problem to be solved with low-sodium food, it requires prompt medical care. About 50% of all salt toxicity cases prove fatal, even with prompt treatment.
What to Look for in a Low-Sodium Food
Low-sodium foods should be nutritionally similar to other foods, aside from the reduced amount of sodium contained therein. They should also exhibit the same characteristics that other high-quality foods do, such as:
- They should feature a whole protein source as the first listed ingredient. Dogs are omnivores, who require a variety of different foods to stay healthy, but the bulk of their calories should come from meat. Look for items like deboned chicken, deboned turkey, lamb, beef, pork, trout or salmon, rather than meat-meals or byproducts made from these animals.
- They should be made in the USA, Canada, New Zealand, Australia, or Western Europe. These countries have very strict safety and food-quality regulations in place, which help to reduce the chances that you’ll purchase a food tainted with harmful substances.
- They should be made without unnecessary dyes, colors, flavors or additives. Your dog probably doesn’t notice his food’s color very much, so colors and dyes are best avoided, as they can trigger food allergies. And foods that require artificial flavors should probably just concentrate on improving their ingredients and recipes, not adding things to cover an unpalatable product.
- They should only contain properly labeled meat meals and meat byproducts. Despite the fact that they often contain items humans would never eat, meat-meals and byproducts can be nutritious and valuable sources of supplemental protein. However, they must be made from identified sources. For example, “chicken meal” is acceptable, but “poultry meal” is not.
- They should emphasize whole-grains and other carbohydrates with a high nutritional value. Carbohydrates are an important component of your dog’s diet, but not all carbohydrates are created equally. For example, enriched wheat provides a very high number calories, while providing very little fiber. Whole wheats, on the other hand, provide a much better fiber-to-calorie ratio.
- They should address any other health needs your pooch has. For example, if your dog suffers from a food allergy to chicken or beef, you need a low-sodium food that doesn’t contain these ingredients. Alternatively, if your dog suffers from arthritis, you probably want a low-sodium food that contains glucosamine or chondroitin.
How to Identify Low Sodium Dog Foods
While we’ve done our best to highlight a few great low sodium diet choices here, it’s worth remembering that formulas can change, so understanding how to do the math yourself is always best.
Generally, when looking for a low-sodium dog food, your best bet will be to look for weight management formulas. These almost always have lower sodium levels than standard dog food.
5 Best Low-Sodium Dog Foods
The following five foods are among the best foods available, that have a relatively low sodium content. While these may not be sufficient for dogs requiring severe sodium restriction, they should work for those with mild sodium restrictions.
Please remember to always consult your vet before embarking on any kind of new diet with your dog – especially when you are trying to meet certain requirements like a low sodium diet.
These formulas have been reported to offer lower sodium amounts than most, but we always recommend getting in touch with the brand’s customer service to verify that the formula has not changed and that the food does indeed meet your and your dog’s sodium restriction requirements. Do not make dog diet selection choices based solely on this article!
Note: Because ultra-low-sodium diets are quite rare, we’ve highlighted the recipes with the lowest sodium content in orange.
1. Earthborn Kibble Adult Vantage
High-quality animal meats with low sodium levels
This kibble features chicken meal and whitefish meal as its first ingredients and a sodium content of only 60mg/100kl.
About: Earthborn Kibble Adult Vantage is a high-quality dog food for canines who need moderate sodium restriction with 60mg/100kl. Many owners sing the praises of Earthborn, testifying to their quality.
This food uses quality animal proteins, with chicken meal and whitefish meal as the first two ingredients. Other ingredients include oatmeal, barley, brown rice, and rye.
While some owners prefer grain-free diets (see below for sodium restricted grain-free kibbles from Earthborn), there shouldn’t be a problem feeding most dogs a dry food that includes some grains, so long as the grains don’t make up most of the kibble composition.
Earthborn also has several other kibbles that are suitable for moderate sodium restrictions:
- Earthborn Weight Control (Grain-Free): 50mg/100kl
- Earthborn Large Breed (Grain-Free): 60mg/100kl
- Earthborn Puppy Vantage: 80mg/100kl

- Earthborn Small Breed: 80mg/100kl
Earthborn is a well-liked dog food brand, with grain and grain-free kibbles that meet the requirements for moderate sodium restriction.
Earthborn is fairly reasonably priced, but not the cheapest option out there. One owner found that one of her bags was only 3/4 full when received, but this seems to be a one-off manufacturing issue. Overall though, there isn’t much bad to say about this brand.
