Dogs are allowed to eat watermelon, but only the flesh of the fruit after removing the seeds and rind. The flesh is safe and nutritious, providing hydration and vitamins A, B6, and C. However, watermelon seeds can cause intestinal blockages, and the rind may cause gastrointestinal upset, so both should be avoided. Watermelon should be given in moderation as a treat and not make up a significant part of the dog's diet.
