9 Best Choices for a Low Sodium Dog Food: 2024 Reviews & Coupons

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.

 

Best Low Sodium Dog Food Brands

If your dog needs a low sodium dog food for medical reasons, consider one of the top brands reviewed below:

1. The Honest Kitchen Whole Grain Beef Recipe Dehydrated Dog Food

What is a Low Sodium Diet for Dogs?

The amount of 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.

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 food options can be tricky, especially if you don’t know where to start looking.

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.

3. Properly labeled meat meals and fat

When selecting dog food, ensure meat is the first ingredient and there are no meat by-products. Properly labeled meat meals, such as chicken or beef meal, are acceptable if the source is clearly identified.

However, avoid vaguely labeled meals like “poultry meal,” “fish meal,” or “meat meal,” as they can include unspecified sources, posing risks for dogs with sensitive skin or food allergies.

Similarly, avoid rendered fats labeled generically as “poultry fat” or “animal fat,” which may come from undesirable sources such as 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

Low sodium dog food offers several benefits, particularly for dogs with certain health conditions.

It helps manage and prevent hypertension, supports kidney health, and reduces fluid retention, which is common in dogs with heart or liver disease.

Additionally, it can help maintain a healthy weight and promote overall well-being by providing balanced nutrition.

Dogs with heart disease or other conditions requiring a low-sodium diet can lead full lives with proper treatment and a healthy diet. It's essential to use clean ingredients.

However, for dogs without medical conditions, consult a veterinarian before switching to a low-sodium diet, as healthy dogs need a certain amount of salt for proper cell function.

Transition any diet change gradually to avoid digestive issues and always seek vet approval for dogs with medical conditions.
