Sodium for Dogs: Electrolytes

Have you ever drank a little too much alcohol, and woke up with a ‘hangover’ the next morning? Most people think this happens because they are dehydrated, which is partially correct. They also feel so badly because they lost so many electrolytes the previous night. For both humans and dogs, and just about any other animal, electrolytes are important for survival.

  • Electrolytes mainly help regulate the flow of water in and out of our cells while helping maintain nerve impulses. We can’t survive without them.

Regulation of blood pressure
Blood volume regulation
Transmission of nerve impulses (signals),
Maintenance of acid/base balance in the body

Too much salt (sodium, NaCl), on the other hand, can be a big problem. Because salt tends to absorb water in the body, too much can lead to dehydration, and in extreme cases – become lethal.

Symptoms of Hypernatremia in Dogs:

  • Increased thirst (polydipsia) and consumption of water
  • Confusion and disorientation
  • Coma
  • Seizures
  • Vomiting
  • Diarrhea

Why Your Dog Might Need This Food

In most normal, everyday cases, your dog’s dietary sodium intake is probably fine. The most common reasons your dog will need to begin a low sodium diet is due to kidney issues or cardiac problems, like congestive heart failure.

In the case of congestive heart failure, your dog’s heart is causing his body to retain sodium he doesn’t need. Excess sodium can cause your pup’s body to begin to retain more and more water. If allowed to continue, this excess buildup can easily become dangerous!

Over time, your dog’s heart could enlarge and be unable to pump blood effectively throughout his body. Circulation problems means less oxygen to the body’s tissues, for any animal (humans included). If the body’s cells don’t get enough oxygen, they aren’t going to function properly.

Some Dog Breeds More Predisposed to Cardiac Issues

  • Basset Hounds
  • Beagles
  • Bloodhounds
  • Spaniels
  • Chihuahuas
  • Collies
  • Golden Retrievers
  • Saint Bernards
  • Weimaraners

Though most commercial dog foods are absolutely fine, extra sodium can be packed on along with dog treats. Keep in mind, dogs weren’t meant to eat treats all day, and commercial dog treats aren’t meant to be a large part of our dog’s diets. Keep your dog heart healthy by monitoring these!

How to Choose the Best

You’ll find several fantastic low salt dog foods here within this article, and clickable links to the products themselves; you don’t even need to leave your home! That being said, there are a few guidelines to watch out for:

Mild sodium restriction 0.3-0.4
Moderate sodium restriction 0.2-0.3
Marked sodium restriction 0.15-0.2
Extreme sodium restriction 0.075-0.15

It’s recommended that most foods offer at least 0.3% sodium. Remember, sodium is required for survival; too much of a restriction could hurt more than help. Healthy dogs don’t necessarily require restrictions (as long as they only eat dog food and avoid human food), and can consume a diet containing the normal levels of sodium found in commercial dog food. Dogs suffering from heart disease or diabetes, for example, will be in need of further restrictions.

Owners would want to consult their veterinarian before severely restricting their pet’s sodium intake. Hopefully owners of dogs with some form of disorder requiring sodium limitations are already consulting a veterinarian!

If your dog is suffering from such high levels of sodium as to be affecting his health, there are distinct causes that are more important than the dog food you are offering:

  1. Underlying medical condition; contact your veterinarian!
  2. Your dog is eating too much human food with added salt. Stick to dog food.

By now, you know that not all dog foods are created equally, and many aren’t designed with special sodium related concerns in mind. Learn to read your dog food labels, and know where to find that particular food’s sodium levels!

Questions & Answers

1. How much sodium should dogs get in their diets?

Remembering sodium is an integral component for any dog’s survival, there really is no magic exact number. Depending on activities, needs might rise or lower slightly. In general, most experts say commercial dog foods should contain at least .3% sodium (point three percent), but most healthy dogs can have a bit more in their diets. Special attention should be given to senior dogs.

2. What happens if my dog overdoses on sodium?

Too much sodium can be very serious, possibly resulting in kidney failure, high blood pressure and cardiac disease, and obvious eventual death (especially in the case of kidney failure). Several of the signs & symptoms of Hypernatremia are listed above.

Because sodium causes cells to retain water, dehydration would likely be one of the signs of overdose, especially if your dog is exhibiting vomiting or diarrhea.

3. Should I supplement my dog’s diet with sodium?

The answer here is usually a resounding NO. In fact, most human foods contain higher levels of sodium than are found in a dog’s natural diet; dogs are usually getting more than enough sodium. On top of this, manufactured dog foods are specially designed to contain the right amounts of sodium for any dog’s diet. Though dog foods are often fine, dog treats can pack on the sodium and should be checked.

Human Foods High in Sodium
Anything purposefully salted or canned
Frozen dinners
Yeast breads
Pizza
All single code sandwiches
Cold cuts and cured meats
Burritos and tacos

The point to remember here is that today’s human diets tend to contain more sodium than what is healthy for a dog. Be cautious when feeding your pet human food.

4. What do I do if my dog begins to show symptoms of dehydration or Hypernatremia (sodium overdose)?

Call then drive your dog to your vet immediately. Simply offering more water may not help much if the problem has become serious. If it is outside regular business hours, contact an emergency veterinarian- there are vets that operate on a 24/7 basis.

5. What is considered low sodium dog food?

Less than 100mg of sodium per 100 calorie portion is considered a low sodium content. Most sources say the overall sodium content should equal less than 0.3% of the total food.

Before you decide to go out and restrict your dog’s salt intake, remember that the Association of American Feed Control Officials (AAFCO) recommended dry dog food contain at least 0.3% sodium.

6. What does sodium even do?

Sodium Chloride (NaCl) in the body is what we call an electrolyte. It works to help produce electrical impulses, exactly as the name implies. Sodium is regulated by the body’s kidneys, and also helps regulate the body’s fluid balance. In a nutshell, sodium helps the body do things like:

absorb and transport nutrients
maintain blood pressure
maintain the right balance of fluid
transmit nerve signals
contract and relax muscles

7. Is less sodium better for my dog than more?

Just like anything else, sodium is fine in moderation. It is even very important! Usually there is no need to limit your dog’s sodium intake. If your dog has a heart, cardiac, or kidney condition, your veterinarian will probably recommend a low sodium diet for your dog.

On the flip side, I don’t know of any manufacturers that sell ‘sodium free’ dog food, or anything close to it, without a prescription. Because salt is vital for a dog’s survival, every dog food should contain at least some (.3% was the standard).

Conclusion

So, the big question is: Do you need to limit your dog’s sodium intake? The answer is probably not. Most commercial dog foods are designed to offer just the right amount of salt in your dog’s diet. You do need to concern yourself with offering too much sodium along with frequent dog treats or human food!
