Can Dogs Eat Watermelon? Benefits, Risks and How Much to Give
Yes, most dogs can eat watermelon in moderation. The flesh is more than 90% water, low in calories and contains vitamins A, B6 and C plus potassium. Remove all seeds and the rind first: both can cause choking or an intestinal blockage. Cut it into small pieces, give it a few times a week and keep treats under 10% of daily calories. It doesn't replace fresh drinking water, and dogs with diabetes should only have it with their vet's approval.

Is watermelon good for dogs?
Watermelon is more than 90% water, so it's a refreshing, low-calorie treat on a hot day. It also contains vitamins A, B6 and C and potassium.
It's not a substitute for water: your dog still needs a full bowl of fresh drinking water at all times. And like any fruit it's a treat, so a complete, balanced dog food should provide at least 90% of daily calories.
How much watermelon can a dog eat?
Treats should be no more than 10% of your dog's daily calories. The amounts below are per serving, offered 2–3 times a week, using pieces about 1 × 1 × ¼ inch.
| Dog size | Weight | Watermelon pieces |
|---|---|---|
| Extra-small | 2–10 lb (1–4.5 kg) | 2–3 pieces |
| Small | 11–20 lb (5–9 kg) | 3–4 pieces |
| Medium | 21–50 lb (10–23 kg) | 3–4 pieces |
| Large | 51–90 lb (23–41 kg) | 4–5 pieces |
| Extra-large | 91 lb+ (41 kg+) | 5–6 pieces |
How to give your dog watermelon
- Wash the outside before cutting so dirt doesn't transfer to the flesh.
- Remove every seed and all the rind, including the pale green layer.
- Cut it into small pieces.
- Serve it fresh or frozen, or mash it onto a lick mat or into a KONG.
- Blend a dog-safe smoothie with plain yogurt that has no sugar and no xylitol.
- Introduce it slowly and watch for an upset stomach.
Watermelon seeds, rind and other risks
- Seeds. A choking risk, especially for small dogs, and many seeds can cause a blockage. A few swallowed by accident are unlikely to cause problems.
- Rind. Tough to chew and digest; it can cause choking or an intestinal blockage.
- Sugar. Natural sugar can be a concern for dogs with diabetes, obesity or sugar sensitivity.
- Too much at once. Can cause diarrhoea, gas, bloating or stomach discomfort.
- Sweets and drinks. Watermelon-flavoured candy, sorbet or drinks can contain added sugar or artificial sweeteners.
Can puppies eat watermelon?
