Watermelon flesh is safe and actually a great hydrating treat for dogs on hot days — it's 92% water and low in calories. However, the seeds and rind are not safe and must always be removed before giving.
Why Watermelons Are Good for Dogs
💧 Excellent Hydration
92% water content — great on hot days or after exercise.
🍎 Low Calorie
Only 30 calories per 100g — very treat-friendly.
🧬 Vitamins A, B6 & C
Supports immune health and skin condition.
❤️ Lycopene Antioxidant
The pigment giving watermelon its red colour has antioxidant properties.
What to Watch Out For
🌱 Seeds Cause GI Blockage
Even small seeds can accumulate and cause intestinal obstruction — always use seedless watermelon or manually remove all seeds.
🟢 Rind Is Dangerous
The hard green rind is difficult to digest and can cause GI upset, blockage, or choking. Always remove completely.
🍬 Sugar Content
High water content dilutes the sugar, but dogs with diabetes should still have limited portions.

| Large (60+ lbs) | 1 cup of cubes | Several times per week |
