Dogs can have coconut water and they usually enjoy it because of its sweet taste. However, it shouldn’t replace plain water as your dog’s primary source of hydration though it can safely be offered in small amounts or added to food or water. Coconut water can help dogs recover from vigorous exercise, especially in hot weather, and it is said to aid digestion. As with any new food, start slowly and monitor your dog’s response.
There are many brands of coconut water, but plain coconut water that has nothing added is the safest for dogs, as some products contain added sugar, fruit purees, or other ingredients that contribute to weight gain. Check labels to be sure the brand you’re looking at does not contain harmful ingredients like xylitol, which is toxic to dogs.
While figures vary, the average cup (245 grams) of 100% coconut water with nothing added contains about 45 calories, 40 to 65 milligrams (mg) of sodium, 10.4 grams of carbohydrates, 9.6 grams of sugar, 0.5 grams of protein, 24 mg of vitamin C, 400 to 600 mg of potassium, and 0.5 mg of manganese. Magnesium, calcium, iron, phosphorus, zinc, and copper are also present in small amounts. Plain coconut water contains zero fat or fiber. Its sodium and potassium are electrolytes, which are minerals that carry an electric charge. They help regulate hydration, maintain pH balance, transmit nerve impulses, and facilitate muscle responses.
If your dog has been diagnosed with kidney disease, consult with your veterinarian before offering coconut water. In some cases, kidney disease depletes potassium so it’s a helpful supplement, but in other cases, coconut water’s extra potassium may be detrimental.
In addition to the water it contains, fresh coconut meat can be a tasty treat for you and your dog to enjoy together. Just be careful when you open the coconut; the husk and shell of the coconut are potential choking hazards. Dogs can also eat dried coconut in small amounts as a treat, but just as with coconut water, check the ingredients for added sugar, which your dog does not need.
