✅ Health Benefits of Watermelon

• Hydration Hero: Over 90% water—ideal for quenching thirst on hot days.
• Low-Calorie Treat: Only ~46 calories per cup—great for weight-conscious pups.
• Vitamin Boost: Packed with vitamins A, B6, C, and potassium for immunity, eye health & electrolytes.
• Antioxidants & Fiber: Supports digestive and immune health with fiber, lycopene, and beta-carotene.

⚠️ Parts to Avoid & Risks

Not all slices are safe:

• Seeds: May contain trace cyanide and pose blockage risk—remove them.
• Rind: Tough and indigestible—can cause GI upset or obstruction.
• High sugar content: Can spike blood sugar—avoid in diabetic or overweight dogs.

🍽️ Safe Preparation Tips

1. Wash the watermelon thoroughly.
2. Remove rind and seeds completely.
3. Cut flesh into bite-size chunks (~½″).
4. Serve fresh or freeze for a cooling snack.
