The Best Low-Sodium Dog Foods

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.

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.

low sodium dog food reviews

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 turkeylamb, 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 corn, 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 in orange the very lowest sodium diets.

1. Earthborn Kibble Adult Vantage

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:

PROS: Earthborn is a well-liked dog food brand, with grain and grain-free kibbles that meet the requirements for moderate sodium restriction.

CONS: 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.

2. Fromm Gold Weight Management

Fromm is another trusted dog food brand that, while they don’t manufacture any food specifically catering to low-sodium diets, a few of their offerings would be suitable for canines who need to cut back on sodium.

The Fromm Weight Management formula clocks in at 70mg/100kcal, making it a solid choice for dogs with mild to moderate sodium restrictions.

PROS: Fromm is a highly reputable dog food brand, and this protein-packed formula designed for weight management also meets moderate sodium restriction requirements.

CONS: Fromm’s high quality dog food can also come as a hefty price point.

Ingredients:

Turkey Liver, Chicken Meal, Pearled Barley, Oatmeal, Dried Tomato Pomace, Duck, Menhaden Fish Meal, Brown Rice, White Rice, Millet, Chicken, Flaxseed, Pea Fiber, Potatoes, Dried Whole Egg, Salmon Oil, Chicken Fat, Lamb, Cheese, Brewers Dried Yeast, Alfalfa Meal, Carrots, Lettuce, Celery, Chicken Cartilage, Potassium Chloride, Salt, Taurine, Chicory Root Extract, Calcium Sulfate, Yucca Schidigera Extract, L-Carnitine, DL-Methionine, L-Tryptophan, Sodium Selenite, Sorbic Acid (Preservative), Vitamins, Minerals, Probiotics

3. Purina Pro Plan Focus Sensitive Skin & Stomach Salmon & Rice Formula

About: Pro Plan Focus is a salmon-and-rice-based recipe that is designed for dogs with stomach sensitivities or food allergies. Salmon and rice are typically not allergens and most dogs are able to digest this food easily. At 50 milligrams / 100k calories, it offers solid sodium restrictions.

  • Made with antioxidant-rich ingredients to help promote immune system function

PROS: Purina Pro Plan Focus has the least sodium per calorie of any of the five foods recommended here. Most dogs appear to love the taste, and it may also provide some relief from food allergies.

CONS: Admittedly, Purina is not the most well-liked brand in the dog food world. However, at a lower price point than the other low-sodium foods listed here, we want to include it as an option. Still, if you can afford other foods listed here, we’d recommend those before Purina Pro.

Ingredients:

Salmon, Canola Meal, Brewers Rice, Barley, Oat Meal, Fish Meal (Source of Glucosamine), Animal Fat Preserved with Mixed-Tocopherols, Salmon Meal, Dried Egg Product, Brewers Dried Yeast, Natural Flavor, Inulin, Fish Oil, Salt, Vitamin E Supplement, Potassium Chloride, Zinc Sulfate, L-Ascorbyl-2-Polyphosphate (Source of Vitamin C), Ferrous Sulfate, Manganese Sulfate, Niacin, Vitamin A Supplement, Copper Sulfate, Calcium Pantothenate, Pyridoxine Hydrochloride, Vitamin B-12 Supplement, Thiamine Mononitrate, Riboflavin Supplement, Calcium Iodate, Vitamin D-3 Supplement, Menadione Sodium Bisulfite Complex (Source of Vitamin K Activity), Folic Acid, Biotin, Sodium Selenite.

This formula is also wheat, corn, and soy free. It also contains no artificial colors, flavors, or preservatives.

PROS: Veterinarians have written in noting that they not only heartily recommend Wellness Complete, but that they give it to their own dogs as well! Some owners have even said that they’ve been able to take their dog off certain medications after feeding their dogs Wellness Complete for a few months.
