Potassium chloride is a common ingredient in dog food.
It’s typically included as a source of dietary potassium and is sometimes used as a sodium substitute for dogs that need to limit their salt intake.
But you’re probably still wondering, what does potassium chloride do for dogs?
Does it help them or hurt them?
Keep reading to learn more about potassium chloride, why it’s in dog food, and how much your dog needs.
What Is Potassium Chloride?
Potassium chloride is a compound made up of potassium and chlorine, both dietary micronutrients.
Together, these two elements also make up a naturally occurring mineral called sylvite.
On its own, potassium chloride is colorless and odorless.
It has been used since the 1800s to treat high blood pressure when taken orally.
Today, it’s used as an intravenous fluid for people with low blood pressure or who are dehydrated.
In addition to these uses, it’s also used as a salt substitute due to its similar taste profile.
Potassium in the form of potassium sorbate is also used as a preservative in processed foods.

Why Is Potassium Chloride in Dog Food
Potassium chloride is added to dog food for two main reasons: for flavoring and to replenish electrolytes lost during exercise.
According to a study published in the Journal of the American Veterinary Medical Association1, some dogs may need more electrolytes than others.
So, it can be a useful addition to dog food, especially if your dog has trouble holding onto water or if they sweat a lot.
Additionally, it adds a salty flavor that many dogs enjoy.
Is Potassium Chloride Good for Dogs?
Potassium chloride is generally considered safe for dogs.
However, there are instances when your dog might not get enough or have too much potassium in their diet, in which case it could cause medical issues.
According to the Journal of the Experimental Analysis of Behavior2, potassium chloride, in regular doses, can lower blood pressure and act as a diuretic.
But when consumed in large quantities, potassium chloride can have the opposite effect and cause high blood pressure.
Ingesting too much may also cause heart arrhythmia or cardiac arrest.
Potassium Chloride Benefits for Dogs
While potassium chloride is an essential nutrient, some potential benefits make it especially beneficial for dogs.

Helps Replenish Electrolytes
Potassium chloride is often added to dog food as a way to replenish electrolytes that are lost during exercise or hot weather.
Electrolytes are minerals that help regulate the body’s fluid balance, acid-base balance, and muscle function.
Reduces the Risk of Sodium-Induced Hypokalemia
Hypokalemia is a condition that can develop when there’s too little potassium in the blood.
It can cause a lethargy, muscle weakness, behavior that looks like drunkenness, and even death3.
Hypokalemia is typically caused by chronic kidney failures but it can be caused by a dietary imbalance where your dog doesn’t consume enough potassium.
Adds Flavor
Another reason potassium chloride is added to dog food is for flavoring.
Many dogs enjoy the salty taste, and it can help make kibble more palatable.
Aids in Digestion
Potassium chloride can help improve digestion by stimulating digestive juices and enzymes.
Reduces Inflammation
Potassium chloride has anti-inflammatory properties that can help reduce swelling and pain associated with arthritis and other joint conditions.
Is Potassium Chloride Bad for Dogs?
Potassium chloride can be harmful in large doses, and additives in dog food should be used in moderation.
As discussed above, too much sodium chloride can cause high blood pressure and other health issues.
Always consult your veterinarian if you are worried about your dog’s health.
Sources of Potassium Chloride in Dog Food
Potassium chloride can be found naturally in many foods we and our pets eat, including meat, dairy products, fruits (particularly citrus fruits), vegetables (especially potatoes), nuts, whole grains, legumes, and seafood.
It can also be found in many processed foods as a supplement or flavoring agent.
How Much Potassium Chloride Do Dogs Need?
The amount of potassium chloride your dog needs will vary depending on their age, weight, health, and activity level.
According to the Association of American Feed Control Officials4, a minimum of 0.6% of your dog’s food should contain potassium, and 0.12% should contain chloride.
Potassium chloride supplies both.
