can dogs drink coconut water

Coconut water is sweet, tasty, and replenishes electrolytes, so you may wonder, “can dogs drink coconut water?” When it comes to human health trends, we often assume that what’s good for us is also good for our dogs. So always better to investigate first.

Coconut water should not be confused with milk or oil, which are two different coconut products. The water specifically may benefit dogs with UTIs and kidney stones, but like any human food, we always need to be careful about feeding our dogs anything in excess.

Coconut water can be good for your dog’s digestion, especially with supplements like a quality probiotic chew. Here, we cover what makes it good for dogs and any health risks it may have.

However, coconut water is a natural drink and is fine as an occasional treat for your dog. However, while it offers hydration, electrolytes, and other benefits, coconut water can never substitute good old plain water.

Before introducing coconut water into your dog’s diet, introduce the beverage gradually. This establishes if your dog can have the drink without creating problems like tummy issues.

What is Coconut Water?

Coconut water is the clear liquid inside the center of green coconuts. It is not the same as milk, which is made with water and coconut meat, and it is not the same as oil, which is the fat or lipids extracted from the coconut.

What Kind of Coconut Water Can Dogs Have?

Dogs can have a small amount of 100% purely natural, additive-free coconut water to enjoy maximum health benefits. However, look for artificial additives in some store-bought products like xylitol, a common sweetener that is toxic to dogs.

Sweetened, xylitol-free coconut water isn’t good either because the added sugar can cause health issues like diabetes and obesity. Sticking to the basics and giving your dog the clear liquid directly from fresh coconut is best, although you can still purchase it from the store.

Health Benefits of Coconut Water for Dogs

Coconut water can benefit your pooch due to its anti-inflammatory properties, nutrients, and electrolyte content. Whether you freeze the drink into dog treats or give it to your dog directly, it’s an asset to your canine’s health.

1. High in Vitamins and Minerals

This drink has several biologically active components like amino acids, vitamins, and minerals that include:

  • Vitamin C – Boosts a dog’s vitality and is a powerful antioxidant
  • B-vitamins – These water-soluble vitamins are necessary as coenzymes for enzymatic reactions vital for cellular function
  • Potassium – Helps in electrical charges of the heart and muscles. Coconut water may be good for dogs with hypokalemia, which is a potassium deficiency. However, a high potassium content can get excessive in dogs (hyperkalemia) if given too much coconut water. If your dog is already ingesting a lot of potassium in their dog food with ingredients like sweet potatoes and liver, be careful. Too much potassium can affect their hearts.

Remember that the ASPCA lists coconut and its products as dangerous to dogs due to high potassium levels.

  • Calcium – Important for bone health in the right amounts
  • Iron – Essential for carrying oxygen in the blood
  • Zinc – Helps a dog’s immune system, coat health, and thyroid function

The next time you’re from intense exercise with your dog, sneaking them a sip of your coconut water can help them rehydrate. The drink contains five electrolytes a dog needs: potassium, magnesium, phosphorus, sodium, and calcium. But remember, no more than a sip.

While coconut water can make a great isotonic drink, nothing can top normal water for hydration. Because of the small amounts of coconut water recommended, your dog will still likely feel thirsty after drinking it.

2. Anti-Inflammatory Properties Aiding in Eliminating Free Radicals

When dogs exercise, the exercise increases the amount of oxygen they burn, causing oxidative damage (or free radicals), which can damage cells. The micronutrients found in coconut water give it anti-inflammatory properties, supporting your dog’s immune system and protecting them from damage.

Eliminating free radicals reduces the chances of arthritis, cancer, and cardiovascular diseases.

3. Improves Digestion

Dogs are famed for their strong stomachs that can handle almost anything, but some dogs do have sensitive stomachs. Dogs can have small amounts cilantro, coconut water, and a dollop of plain yogurt to aid their sensitive stomach as a temporary solution.

This beverage contains monolaurin, a monoglyceride that soothes and cleanses the digestive tract. Additionally, this water is high in manganese which activates enzymes used in metabolism and regulates bowel movements.

4. It May Help Reduce Kidney Stones and UTIs

Kidney stones and urinary tract infections (UTIs) can result in dogs with a low thirst drive or who don’t drink enough water. These dogs can benefit from adding a bit of flavor to their drink, which can be achieved with coconut water. More dog-specific studies on the UTI function of coconut water are necessary, but research on humans seems promising.

As a natural diuretic, coconut water can flush out toxins by promoting diuresis (increasing how often a dog needs to pee) and reducing UTIs. High potassium levels in the drink can play a key role in dissolving some kidney stones, reducing their size.

Remember that dogs get different kinds of kidney stones; some need to be removed surgically, and what works to dissolve one kind can cause another. So it’s vital to have a veterinarian assess any stones in the urinary tract.

Health Concerns of Coconut Water

Unfortunately, dogs should never have too much coconut water. Dogs that frequently take plenty of coconut water are at risk of gastrointestinal issues and hyperkalemia, among other problems. Let’s look at some of the risks coconut water may pose to dogs.

1. Gastrointestinal Upset

This is the most common side effect of coconut water in dogs. Dogs with an upset stomach exhibit the following:

  • Vomiting;
  • Diarrhea;
  • Lack of appetite;
  • Discomfort; and
  • Pacing.

2. Hyperkalemia

Dogs that take too much coconut water can suffer from hyperkalemia due to excessive potassium levels. This is a severe condition that’s thankfully rare but requires medical attention. Signs include:

  • Vomiting;
  • Lethargy;
  • Weight loss;
  • Dehydration;
  • Muscle loss;
  • Breathing problems; and
  • Paralysis.

3. Obesity

Coconut water has a high-calorie content of about 60 kcal per cup. Coconut water must be kept within your pooch’s daily caloric allowance to stay within a healthy weight. Excessive coconut water can cause weight gain, then obesity.

Obesity poses major health risks to dogs, including diabetes, high blood pressure, cancer, and heart disease.

How to Give Your Dog Coconut Water: How Much Coconut Water is Okay for Dogs?

The exact amount of coconut water to give your dog isn’t a one-size-fits-all, and it varies based on your dog’s size. A few ounces every few days a week will suffice. It’s essential to introduce the drink gradually in tablespoon amounts to determine if your dog reacts to it.

Some dogs with sensitive stomachs may react negatively to coconut water with an upset stomach. Others are allergic to the drink, although allergies are quite rare.

You Can Serve Your Dog Coconut Water This Way:

  • Mix a couple of ounces into their drinking water;
  • Give it to your dog directly as a treat; or
  • Freeze and give to your dog as a frozen treat.

Can Dogs Have Coconut Milk?

Dogs should not have coconut milk as a regular part of their diet. Remember that coconut products are listed as dangerous to dogs because of the high levels of potassium.

Coconut milk is higher in fat and is a mixture of shredded coconut flesh and water. The greater fat content makes coconut milk risky to your dog’s weight when given in large quantities over long periods.

Excessive consumption leads to stomach upset with diarrhea and vomiting.

Can Dogs Drink Coconut Oil Everyday?

Coconut oil is high in fat and shouldn’t be taken by dogs every day. Excessive coconut oil will cause stomach upset in dogs and obesity after extended use. A ¼ teaspoon for small dogs and a teaspoon for big dogs should be enough for dogs that don’t react to coconut oil.

Frequently Asked Questions (FAQS)

Is coconut water good for a dog’s skin?

Coconut water may be good for dog’s skin and coat. The drink is high in B vitamins that promote coat health and eliminate free radicals that would damage the coat. It also has antibacterial and antifungal properties that support skin health.

Is coconut water good for dogs with UTIs?

Coconut water helps dogs with UTIs by increasing urine production, which flushes out toxins. Additionally, the potassium content in the drink helps dissolve some kidney stones, effectively reducing their size. The drink also encourages dogs with UTIs to drink more water.

Is coconut water good for dogs with parvo?

Parvo causes sick dogs to lose water excessively due to diarrhea and vomiting, which can lead to severe dehydration and death. Dogs recovering from parvo can benefit from coconut water as it replenishes electrolytes in the body, reducing dehydration. But your dog will still need immediate medical treatment.

Is coconut water good for a dog’s diarrhea?

Coconut water helps a dog with diarrhea by introducing electrolytes that are lost. If the diarrhea results from indigestion, coconut water reduces it because the drink aids digestion. Other digestive issues like constipation can improve with coconut water and other home remedies aiding dog scooting.

Can coconut water give a dog diarrhea?

Coconut water can cause diarrhea if dogs drink it in large quantities. Gastrointestinal issues are easy to spot and cause vomiting, diarrhea, and reduced appetite. Dogs with sensitive stomachs can have diarrhea even with little coconut water.

Final Thoughts

Dogs can safely drink coconut water and enjoy benefits like rehydration, better digestion, and nutrition. Coconut consumption should be controlled in dogs to prevent gastrointestinal issues and obesity due to its high fat content. Coconut oil and milk are other coconut by-products that benefit dogs in small quantities.
