The full answer
Watermelon flesh has nothing in it known to be toxic to dogs, and it's mostly water, which makes it a popular hot-weather treat.
Preparation matters more here than with most fruits: the rind is tough and hard to digest, and seeds can cause problems in quantity, especially for small dogs.
Why plain flesh is SAFE: the red flesh is mostly water, low in calories and not toxic to dogs. The concerns are the other parts and the amount. The tough rind can cause choking or an intestinal blockage, many seeds can be a choking or blockage risk, especially in small dogs, and a large helping of any watery, sugary fruit can upset the stomach. Dogs with diabetes may need to avoid it; ask your vet.
Is Watermelon Good for Dogs?
Watermelon is around 90% water, low in calories and contains vitamins A, B6 and C.
It is a refreshing snack, not a hydration strategy — dogs still need constant access to fresh water.
