9 Best Choices for a Low Sodium Dog Food: 2022 Reviews & Coupons

low sodium dog food

Is low sodium dog food a must? Sodium is a type of mineral and one that plays an important role in your dog’s health and wellness. It can generally be found in your dog’s blood and in the fluid that surrounds his cells, helping to maintain the proper fluid balance in his body.

Sodium keeps the cells from swelling too much or from becoming dehydrated and it also plays a role in the healthy function of your dog’s nerves and muscle cells. 

The Association of American Feed Control Officials (AAFCO) recommends at least 0.3% sodium in the diet for a healthy dog for both adult maintenance and the growth and development of puppies. 

For certain dogs, however, too much sodium can be problematic.

What is a Low Sodium Diet for Dogs?

For most dogs, excess sodium intake is not a problem because healthy dogs just excrete it through their urine. But in certain canines, their medical problems prevent them from being able to do so. 

For example, pups with high blood pressure, congestive heart failure, liver or kidney disease, and other conditions simply cannot abide high sodium levels. Salt exacerbates their disease. If their sodium intake is not restricted, it can lead to strokes and heart problems, and worsen their condition.

For pups such as these, a low-sodium diet is often prescribed by the veterinarian. However, if your dog doesn’t take to the new diet, shopping for alternative low-sodium dog foods can be tricky, especially if you don’t know where to start looking.

Sodium Levels

How much sodium you feed your dog depends on his condition. Normally, the sodium levels of dog food for dogs with mild sodium restriction ranges from 0.35% and 0.5%. A moderate sodium restriction requires dog food to contain between 0.1% and 0.35% only. 

There are plenty of prescription diets out there offered by popular brands, and the selection process can be overwhelming.

Also, popular brands that offer low-sodium dog foods aren’t necessarily the right choice—many of them are made with low-quality ingredients which could cause other health problems for your dog. 

So how do you choose? In this article, we review some of the best low-sodium foods out in the market. We’ll also show you what things to consider when selecting a lower sodium diet so you can make an informed choice.

How To Select Low-Sodium Food For Your Dog

Since high sodium levels can exacerbate a dog’s medical condition, it’s important that you take the points below into consideration when purchasing a dog food for your pooch.

It’s not enough that the food is declared as a low-sodium diet. The dog food should also meet high-quality standards for your pup’s overall health.

1. No fillers

Many popular commercial dog foods trade quality for affordability. If you’ll check the labels of these dog foods carefully, you’ll see corn gluten meal, soy, and other ingredients have been added. Dog food manufacturers add these as fillers to bulk up the food but these contain little of the essential nutrients that your pet needs.

2. Meat as the first ingredient

Dog foods should be high in protein, and you can tell a high-quality dog food by the first few ingredients in the label. If these are made up of proteins, then it’s worth a closer look.

If it’s not (unless it’s wet food and the first ingredient is water or broth, both of which are okay), then you should probably remove that food from your cart.

And it shouldn’t be just any kind of meat. Meat by-products are not what you’d want to feed your pet. While meat by-products may refer to offal such as heart or kidneys (which are healthy), they can also refer to blood, hide, and virtually all part of the carcass. You won’t know which unless the dog food label specifically states it.

9 Best Choices for a Low Sodium Dog Food: [year] Reviews & Coupons 25

3. Properly labeled meat meals and fat

So that dog food has meat as the first ingredient and no meat by-products. So far, so good. Check next if the dog food contains meat meals and if these are properly labeled.

Some meat meals are fine, like chicken meal, beef meal, and so on. As long as the animal from which the meat comes from is identified, then you should have nothing to worry about.

However, some meals are listed in very vague terms. For example, you might come across something like, “poultry meal” or “fish meal.” Worse is when it simply says, “meat meal,” which is even more vague. The food could contain anything.

This becomes even more problematic when your dog has sensitive skin or food allergies.  How will you know if the dog food contains something that might trigger your pet’s condition? 

The same goes for rendered fat that is simply labeled as “poultry fat” or “animal fat.” These unidentified fats can mean—and often does in the pet food industry—that the fat came from dead, disabled, or diseased animals.

4. No artificial flavors, colors, or preservatives

Dog foods should not contain these. Artificial flavors and other artificial additives do not contribute anything to the meal. They may even aggravate medical conditions, and worse, be carcinogenic. 

If it’s a carefully crafted dog food, then there’s no need to include artificial flavor. The meat and other ingredients in a quality dog food will be enough to entice even the pickiest pets.

5. A carefully balanced diet

A good low-sodium diet should not only focus on how much sodium is in it but also on the ingredients that give it a high nutritional value.

Protein and quality fat sources are important, but the presence of vegetables, fruits, and other ingredients that deliver essential mineral and vitamin content should also be considered when selecting your pup’s dog food.

6. Beware of dangerous dog food ingredients

Some dog food brands try to entice canines to eat by putting unnecessary ingredients that can possibly become harmful to your pet.

Sugar is one example. It comes in many forms, like corn syrup, molasses, or sucrose. Sugar, when given regularly, can lead to diabetes and difficulty in weight management.  

Another dangerous ingredient is carrageenan. Although there are scientists on both sides of the fence on carrageenan, it has been found to be without nutritional value.

There are also studies that even food grade carrageenan degrades in the stomach and can be potentially harmful to the pets that ingest it.

7. Moisture

Since salt helps deliver water to a body’s cells, a low-sodium diet can increase the risk of dehydration in your dog.

If your pup is not fond of drinking water too much, consider switching him from dry food to wet dog food. Wet dog food typically contains anywhere from 75% to 82% moisture.

Canned food also typically contains no preservatives because the heat treatment in the canning process prevents the food from spoiling until the canned food is opened.

8. Sodium Content

This is the most important part. We’ve listed the as-fed and dry matter percentage of our reviewed dog foods since sodium restrictions require food to strictly adhere to it. 

What’s the difference between the two? 

Dry matter is the value for sodium when all moisture is removed from the food, while as-fed would be the food’s value for the sodium if the moisture was not removed. As the water content increases in food, the amount of other nutrients present decreases.

Common Medical Conditions That Need Low Sodium Food To Manage

As stated before, there are several medical conditions that warrant low-sodium food. These include but are not limited to:

  • Kidney disease
  • Congestive heart failure
  • Liver disease
  • High blood pressure
  • Hypernatremia

Heart diseases, including congestive heart failure, affect the way blood is pumped throughout the body, which may then cause excess fluid to build up. This excess fluid puts pressure on the heart, lungs, and kidneys. Excessive sodium intake can aggravate this life-threatening condition.

The kidneys’ job is to filter out excess sodium and minerals from the body. When dogs have a kidney disease, their kidneys do not function as well. Too much salt intake will also put further stress on their already suffering kidneys. 

High blood pressure can stem from an underlying disease, and this can be anything from chronic kidney disease and Cushing disease to adrenal gland tumors.  High blood pressure can be effectively managed by treating the underlying disease, through medication, and via low-sodium food.

The liver’s function is to remove the toxins from the blood. When a dog has liver disease, his liver is not at its peak performance. And when salt intake is not managed, further stress is put on the overworked kidneys.

However, dietary sodium restrictions can help manage the disease and its effects on your pup’s body. Hypernatremia, or salt toxicity, is a condition that happens when your pup ingests something with too much salt, but they can’t get enough water to dilute the sodium they ingested.

When salt toxicity occurs, providing fresh water to your pup is imperative. And to make sure it does not happen again, a mild sodium restriction may be imposed.

Our Final Take

Most dogs with heart disease or any of the other medical conditions that require a low-sodium diet can still live a full life provided that their condition is adequately treated and maintained. That includes providing him with food that is as healthy as possible. And by this we mean, clean ingredients. 

If your dog does not suffer from any medical condition, please ask your veterinarian first before switching him over to a low-sodium diet.

Get 60% off your first order  

A healthy dog’s diet needs a healthy helping of salt—between 0.25 g to 1.5 g per 100 grams of food—for his cells to function properly. Putting healthy dogs on low-sodium diets can do more harm than good.

Each dog is different, and their reactions will vary depending on the food. We have researched these foods thoroughly, however, any change in diet for a dog that has a medical condition still needs your vet’s full approval. 

Just make sure to transition your pup slowly before giving him new food to avoid digestion issues.
