This is my detailed guide about the best low sodium dog food in 2021.

Sodium is a valuable and essential mineral in the diet. All dog food should contain it, and an average dog shouldn’t have a problem with excessive intake either. However, certain health conditions require a low-sodium diet and dog food that supports such a diet. 

For my article, I did many hours of research to write in detail about the problem. Besides, I also collected 8 matching products. 

In my opinion, The Honest Kitchen Whole Grain Beef Recipe is the best low sodium dog food. However, check out the other brands I included if you are interested in other options. 

I am confident that by the end of my article, you will be able to decide which is the best choice for your pup.

Let’s start!

8 best low sodium dog food

Below you will find my list of the best low sodium dog foods. Each contains high-quality ingredients and provides the maximum amount of nutrients your dogs need at low salt content.

I will always try to indicate the sodium content of the products. Sometimes these data will be expressed as a percentage, sometimes in mg/100kCal, depending on which data I found in my research.

You should consult your veterinarian before making a final decision. And remember, the diet change should be gradual.

What are the recommended levels of sodium for dogs?

Sodium is an essential mineral that plays a key role in many bodily processes. Examples are the normal functioning of nerve and muscle cells. 

In fact, you should generally not be afraid of your dog’s excessive sodium intake. According to a 2008 study, dogs can adapt to high sodium levels. 

Excess is excreted in the urine. So you don’t have to worry about your dog developing high blood pressure due to excessive sodium intake. 

But as I mentioned, this is only the case for healthy dogs. Certain health conditions require some degree of restrictions. I will write about these conditions later, but now, here are the different sodium level requirements:

  • No sodium restrictions: >100mg sodium/100kCal , or >0.5%
  • Mild sodium restriction: 80-100mg sodium/100kCal, or 0.35-0.5%
  • Moderate sodium restriction: 50-80mg sodium/100kCal, or 0.2%-0.35%
  • Marked sodium restriction: 40-50mg sodium/100 kCal, or 0.15-0.2%
  • Extreme sodium restriction: 20-40 mg sodium/100 kCal, or 0.075-0.15%

Two things complicate the situation. On the one hand, the AAFCO guidelines do not specify a maximum sodium intake for dogs. 

This is helped by the fact that the National Research Council of the National Academies guidelines, on the other hand, contain a maximum value for the sodium intake of dogs. 

According to this, a dog weighing 30 pounds with average activity can consume 2 grams of this mineral per day. 

This isn’t easy to convert to larger dogs because bodyweight does not linearly increase the amount of sodium your dog can consume. However, this number can be a good starting point. 

Another difficulty is that manufacturers do not always indicate the sodium content of products on the packaging. In this case, it is safest to call them. I gave the percentages because it’s usually a lot easier to figure out. 

It is important always to consult a veterinarian or dog nutritionist regarding sodium restrictions.

Salt

Health Conditions that Require Low-Sodium Dog Foods

As I mentioned, there is no association between high blood pressure and salt intake in dogs. However, some diseases require a low-sodium diet. I will write about these below.

Heart problems

Congestive heart failure is a heart disease in which you have to feed your dog a low-sodium diet. This is true even if the problem has not yet developed, but there is a risk. In heart disease, the body of dogs cannot get rid of excess sodium. This causes water retention, which also has a detrimental effect on other organs. The consequence can even be fatal.

Liver Disease

The liver is the most effective detoxification and waste removal system in the body. Also, it has several key roles in the functioning of the body. If a dog has liver disease, this organ is unable to perform its function. This can have severe consequences. A low sodium diet can help a lot with the problem.

Kidney Disease

One of the kidneys’ functions is to filter out and excrete minerals (such as sodium) in the urine. If this vital paired organ has a disease (e.g., kidney disease or renal failure), then your dog will not be able to remove excess sodium from his body. It can also lead to excessive water retention, which can even be fatal.

Ascites

The diseases mentioned above can result in the leakage of blood and other fluids into the abdominal cavity. These fluids can accumulate, which hurts the dog’s internal organs. This is another reason why a low-sodium diet should be considered in such cases.

What about salt toxicity in dogs?

As you can see, you need to be careful about how much salt your dog consumes for certain diseases. 

However, a large amount of sodium intake at one time can be a problem even for healthy dogs. This is salt toxicity. 

The lethal dose for canines is about 4g/kg body weight. Smaller amounts can cause symptoms. These include vomiting, tremors, and seizures. If you notice any signs of salt toxicity in your dog, contact your veterinarian immediately. 

Try to avoid the problem by not giving your dog foods high in salt.

Are there any benefits to a low sodium diet in dogs?

If your dog has any of the health conditions mentioned above, it is inevitable to reduce the diet’s sodium content. However, a low sodium content may be an advantage in other cases.

Proper hydration

The salt has an outstanding water absorption capacity. For this reason, your dog should try a low-sodium diet for adequate hydration.

Senior dogs

Elderly dogs are more prone to various diseases such as organ diseases, decreased muscle and nerve function, etc. The low salt content can help prevent these conditions from developing or getting worse.

Of course, keep in mind that the diet should include a minimum sodium level for healthy dogs. (100mg sodium/100kCal, or 0.5%)

What are the types of low sodium dog food?

Overall, it can be said that there are also the same types of low sodium dog foods as other dog foods. These are the following:

Dry food

This is perhaps the most popular type. It is manufactured in dry kibble form and has a very crisp texture. In general, this is the most economical version and has a longer shelf life than the others. It also helps keep your dog’s teeth clean. However, this is not the best choice for dental problems.

Wet food

Wet foods are very popular with dogs as they have a much more tempting texture. This type of food is also the right choice if your four-legged friend has some dental problems. These products contain a lot of moisture, so they help with hydration. 

However, due to their high moisture content, their shelf life is also significantly shorter. You can buy them in cans or packages.

Treats

There are several forms of treats, depending on the intended use. More importantly, you should find a product that is low in salt. Look for natural and whole ingredients on the packaging. Examples include real meats, fruits, and vegetables. 

The worst treats can be delicious, but they do contain a lot of harmful ingredients.

How to choose the best low sodium dog food?

Basically, good low-sodium dog food should have a similar nutritional value as other products. The main difference, of course, should be in the salt content. 

You also need to know what your dog needs according to breed, life stage, and size. High-quality dog ​​food has the following characteristics:

Protein content

slice of meat

The protein content is the most important factor you need to consider when looking for the best dog food. Dogs are omnivores, meaning they can digest various macronutrients. Nevertheless, the primary ingredient must be some source of protein. 

Meats are clearly the best for this. Chicken, turkey, lamb, beef, and fish are all high-quality protein sources that provide dogs with the right amount and quality of amino acids. 

It is important to note that there are three popular forms of meat. Real meat, meat meal, and meat by-product. In unchanged form, real meat gets into the food with minimal processing while preserving nutrients. 

Meat meals are not preferred by many. However, you should know that these are concentrated, minced, and moisture-free forms of real meat. That is, their quality is usually no worse than real meat. 

Meat by-products contain a lot of glucosamine and chondroitin. These are the “vitamins” of the joints. However, meat by-products cannot be considered a complete and quality source of protein, as in many cases, they consist of parts of animals such as tendons, organs, etc. 

Make sure the meat meal and meat by-product are named and properly labeled on dog food. Poultry meal and the poultry by-product are not very reassuring. Chicken meal and chicken by-products are more of what you should choose.

Long story short, strive to choose a product whose first ingredient is real meat or meat meal.

Carbohydrate content

Dogs can utilize carbohydrates and gain energy from them. However, the quality of carbohydrates is at least as necessary as that of proteins. Complex and whole carbohydrates contain plenty of useful fiber, vitamins, and minerals. 

The sensitivity or allergy of dogs can determine the source of carbohydrates chosen. Some dogs are sensitive to grains for example. For them, you should look for grain-free recipes.

Other nutrients

Vitamins, minerals, antioxidants, and other useful nutrients are important supplements to a dog’s diet. These are natural sources of fresh fruits and vegetables. But some products also contain added vitamins and minerals. 

Other useful supplements include fish oil, probiotics, and glucosamine. There can be significant differences between brands, so you should always check the ingredients listed on the packaging.

Controversial ingredients

Artificial ingredients such as preservatives, flavor enhancers, and colorants should be absolutely avoided in a dog’s diet. This is because they indicate that the product is of low quality and can also cause allergic reactions in many dogs. 

Your dog won’t appreciate the color of the food anyway. And if a product contains artificial flavors, it is conceivable that the ingredients have not been carefully selected.

Manufacturing countries

In most cases, the packaging of the products indicates where they were made. The best countries are the USA, Canada, Australia, New Zealand, and Western European countries. These are stringent regulations for production processes. Thus, there is less chance that the chosen product will contain harmful substances or impurities.

Individual needs

As with humans, individual differences can occur in dogs. Examples are various allergies, sensitivities, or other diseases. Clarify these conditions with your veterinarian and choose low-sodium dog food accordingly.

Ingredients to avoid for dogs on low sodium diets

When your veterinarian recommends a reduced sodium intake for your dog, there are some ingredients you should avoid. These are the following:

  • Nitrates: Sodium nitrate is a preservative found in many processed types of meat (e.g. bacon or ham). These should not be included in your dog’s diet as they can raise the level of sodium in his blood.
  • Monosodium Glutamate: It is a flavor enhancer that is high in sodium. Avoid it. Anyway, which dog food needs to be flavored is probably not very good quality.

Human foods to avoid

hamburger menu

I do not support giving human food to our dogs. On the one hand, they can be a danger to our four-legged friends in many cases. On the other hand, human foods usually contain more salt, which can be unhealthy for dogs. This is especially true for processed foods. You should definitely avoid the following:

  • Potato chips 
  • Sausages
  • Bacon
  • Other salted meats
  • Pizza
  • Bread
  • Sauces (Soy sauce, ketchup, etc)
  • Cheese
  • Popcorn
  • Human biscuits
  • Canned vegetables

How can you identify low-sodium dog food?

The products listed in my article are excellent options if you want to provide your dog with a low sodium diet. However, it doesn’t hurt if you’re also aware of how to identify these dog foods. 

The key is to look at the label and look at the sodium content. Various nitrites, salts, and preservatives can also contain sodium. 

It is also a good idea to ask your veterinarian to recommend a good recipe. 

In general, weight management and heart health formulas have lower sodium content than other commercial dog foods. Therefore, if you start your product search with them first, you will probably be on the right track.

Frequently asked questions about low sodium dog foods

How can I switch my dog’s diet to low sodium?

The digestive system of dogs prefers consistency. For this reason, any dietary change should be careful and gradual. A properly executed gradual switch will take 1-3 weeks. It is best to seek the advice of your veterinarian about all this.

Can dogs have low sodium?

Higher salt intake doesn’t have any harmful effect on average dogs. Our dog has a medical condition such as kidney, liver, and heart diseases. In such cases, it is important to reduce sodium intake. Be sure to talk to your veterinarian about this.

My final choice

Once you have discussed your dog’s diet with your veterinarian about the sodium levels, you can start looking for the right products. 

Low sodium content is not enough. The quality of the ingredients is at least as necessary. The health of our dogs is based on the best possible nutrition. 

I found The Honest Kitchen Whole Grain Beef Recipe to be the best of the options listed here. Not only does it offer a solution to the problem detailed in my article, but it is one of the healthiest dog foods on the market thanks to its premium ingredients and processing. 

By the way, I strongly recommend the other options as well, as I have tried to be as careful as possible in my research. 

Remember to change your dog’s diet gradually and consult your veterinarian.
