Dogs can eat cantaloupe safely but only in moderation. The fruit is non-toxic and provides beneficial nutrients like vitamins A, B6, C, fiber, and antioxidants, as well as hydration due to its high water content. However, only the flesh should be given to dogs; the rind and seeds must be removed beforehand because they can cause choking or digestive issues. Dogs with diabetes or overweight conditions should avoid cantaloupe due to its high sugar content. Treats like cantaloupe should make up no more than 10% of a dog's daily diet, and small, manageable pieces are recommended to prevent choking. If any allergic reactions or digestive issues occur, stop giving cantaloupe and consult a veterinarian.
