Short answer

Coconut water is not worse for a 5 kg dog than orange juice — it is safe to offer in small amounts. The main difference is that coconut water is high in potassium, which is fine for a healthy dog but could stress the kidneys if your pet already has kidney disease. Orange juice, by contrast, is high in sugar and acid and offers no real benefit. Give plain coconut water without added sweeteners, stick to a few sips, and call your own vet if your dog vomits or seems unusually lethargic.

A small amount is safe, but it is high in potassium — skip it if your pet has kidney disease.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Coconut water is not toxic to dogs. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.
