The full answer
Watermelon flesh contains nothing known to be toxic to dogs and is mostly water, which makes it a popular hot-weather treat.
Preparation matters more 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 about 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.
