Can dogs eat coconut water?

Yes — in small amounts, plain only

Yes. Plain unflavoured coconut water is safe for dogs in small amounts and provides electrolytes. Flavoured versions aren't.

The full picture

Coconut water is a natural source of potassium, sodium, and other electrolytes, and in small amounts is safe for dogs. It's sometimes used as a mild rehydration fluid. A splash in water bowls on hot days or after exercise is fine. Avoid flavoured coconut waters (added sugar, often chocolate or fruit flavours), and don't replace water with coconut water — dogs need plain water as their main drink. Dogs with kidney problems should skip it because of the potassium.
