Why Low Sodium Foods Are Needed for Your Dog

Why should you consider options like low sodium wet dog food? This is a critical question since it’s important to know why you should even consider low-sodium products.

The commercial pet food industry is big business and last year reached sales of about $75 billion worldwide. Buying wet food or kibble for your dog can provide many benefits.

The main one is convenience since many pet owners don’t have the time or energy to prepare homemade food for their doggies. Fresh is best, but sometimes there aren’t enough hours in the day.

Dogs actually need some salt in their food. It can provide benefits for their nervous system and muscles, for example. Just like salt can add flavor to human food it can also enhance flavors of dog food.

The best answer usually isn’t a no-sodium diet since it can also cause some unwanted health conditions. The key is to pick food that contains about 0.3% sodium.

The problem is many dog foods on the market today are loaded with salt. Just like humans, dogs can develop health problems when they consume too much salt. High sodium diets can cause various serious diseases. The good news is you can change your mutt’s diet to help prevent them.

Feeding your dog low-sodium food can provide several benefits including:


A low-sodium diet can help to boost your dog’s energy levels. That, in turn, can help to keep your canine fit and boost its overall health.

Control blood pressure

Low-sodium food helps to prevent the dog’s blood sugar level from increasing. It also helps to control blood pressure. These benefits help to make the dog look healthy and active.


If your dog is eating a low-sodium food, then the skin/hair will be healthier. A high-salt diet can cause problems like dry skin and dull coat.

Lower body fluid

When the kidneys retain sodium, this produces less urine. That, in turn, can cause a spike in blood volume.

Strong immune system

A low-sodium diet can help boost your dog’s immune system. This, in turn, will help to prevent various possible health conditions you’ll certainly want to avoid.

Prevents kidney/liver/heart disease

If you want to improve your dog’s heart health, then consider low-salt food. This can help to maintain a healthy heart and prevent various conditions like heart disease.

The old saying “prevention is better than cure” certainly applies to salt food in dog food. This is why you should start feeding your dog low-sodium options as soon as possible.

That brings us to a common misconception that only old dogs need low-salt diets. In fact, young dogs/puppies also need that kind of food since they can suffer from the same negative effects of consuming too much salt.

What to Look For in Low Sodium Dog Food

When you pick a dog food that’s low-sodium here are some of the things to look for:


When picking a low-salt dog food make sure to consider whether it’s designed for certain dogs. That includes different breeds, sizes, and ages.

There’s usually a range in terms of the dog’s weight, big/medium/small breeds, and age. It’s a plus since it will be easier to find the right food for your mutt.


When picking a low/no salt dog food, it’s important not only to consider the salt content. This is certainly important to make sure “low salt” really is that. On the other hand, you should also consider the other nutrients contained in the food including:

  • Vitamins
  • Minerals
  • Protein/Carbs/Fat
  • Omega-3/6
  • Antioxidants
  • Probiotics

Look for dog food that’s low in fillers. Many companies today add various ones like soy, corn, wheat, etc. This lowers the cost of the dog chow but also reduces the nutritional value.

While low-salt food is healthier, it’s also important for food to be high-protein. This is the most important macro-nutrient for dogs, and the protein source should be the first one listed on the label. In addition, the protein source should be a good-quality one to make sure your dog is getting the healthiest food possible.

You should also consider whether the food contains artificial colors, flavors, and preservatives. These can make the dog food look/taste better but can also cause health issues for your pet pooch.

Limited Ingredient/Hypoallergenic

Your dog might have health conditions that also require these options besides low-salt. For example, hypoallergenic foods are a good option if your dog has allergic reactions to certain ingredients like chicken or wheat, for example.

Then there’s also limited-ingredient dog food. This usually includes one protein source, one carb source, and a small number of other ingredients. The small number of ingredients can provide various health benefits and help to deal with other health conditions your dog has.

Low/No Sodium

In some situations, you should consider a no-sodium dog food. For example, if your dog has an extreme medical condition, then it might be important to reduce all sodium until it recovers.

That said, in most cases, you should consider a low-sodium food. That’s because sodium can actually provide various health benefits related to the dog’s heart, kidneys, immune system, skin/coat, fluid, etc. If you eliminate all sodium from your dog’s diet, it can ironically cause new health issues, which you’ll likely want to avoid.

Wet/Dry food

Dogs tend to prefer wet food over kibble because it’s more like “real” food, but different dogs have different tastes. Wet food usually has more protein and fewer carbs than dry food. They also usually lack artificial preservatives since they’re in air-tight packaging.

On the other hand, kibble can also provide various benefits for your canine. Many dogs prefer the crunchiness of dry dog food. It also gives their teeth/jaws a better workout than canned food, so there’s that.

Another plus of kibble is longer shelf life. So, if you live far from the local supermarket or pet store, for example, low-salt dry food might be a better option.

Recommended Sodium Levels for Dogs

Dogs require a certain amount of sodium. When picking a dog food, it’s important to know the recommended level of sodium.

Different dog foods have a wide range of sodium levels. The bad news it can be tough to determine sodium levels of several good brands. The problem is dog food makers aren’t technically required to add that info to the labels.

The news isn’t all bad. If you do your homework, you can still learn the sodium content of dog food products. This, in turn, helps you pick one that’s within the range of sodium content that your dog’s veterinarian prescribes.

Animal doctors usually discuss low-sodium diets in terms of the sodium/100K calories when comparing different foods. Here are the main categories:

  • Dogs w/ no sodium restrictions: Foods with minimum 0.5% sodium content
  • Dogs w/ mild sodium restriction: Foods between 0.35%to 0.5% sodium content
  • Dogs w/ moderate sodium restriction: Foods between 01l.% to 0.35% sodium content
  • Dogs w/ severe sodium restriction: Foods under 0.1% sodium content

The Association of American Feed Control Officials (AAFCO) only establishes a minimum acceptable level of sodium but not a maximum amount. It’s also worth noting the National Research Council of the National Academies does provide guidelines.

The guidelines state a dog that weighs 33 pounds and burns around 1,000 calories/day shouldn’t consume over 2,000 mg/day. This is a basic guideline you can use to determine how much sodium your dog should be consuming on a daily basis.

Recommended Alternative Low Sodium Foods

If you want to pick low or salt-free dog food, then it’s important to pick foods that are low-sodium. In order to add flavor to your pet’s food, you can do it without salt and here are some of the best options:

  • Blueberries
  • Ginger
  • Green Peppers
  • Parsley
  • Peanut Butter
  • Sage
  • Tomatoes

If you make homemade dog food, it’s highly recommended you not add any salt to it. The reason is it can cause various health problems that can be serious. You can use the above-mentioned ingredients to add flavor to dog food without salt.

Onions and garlic are ingredients that are often debated in terms of whether or not they’re healthy for dogs. There’s a lot of debate among experts. Both are considered toxic to cats/dogs, but garlic is 5x more toxic than onions. In addition, certain breeds/species are more sensitive than others.

So, it’s highly advisable to avoid feeding your dogs garlic in particular. Onions are iffier but if you want to be on the safe side then avoid both of these herbs in your homemade dog chow.

Foods to Avoid for Dogs on Low Sodium Diets

If your dog is on a low-sodium diet, then it’s critical to consider options like low sodium wet dog food brands. Here are some of the salty foods you should never feed dogs:

  • Bacon
  • Canned beans
  • Canned Entrees
  • Hot dogs/sausages
  • Pizza
  • Popcorn
  • Potato chips
  • Pretzels
  • Salted Meat
  • Salted nuts
  • Salted peanuts

Key Takeaways
