Yes, dogs can eat watermelon. The pink flesh is safe for most dogs as an occasional treat, and it's low in calories and full of water. Before you share, remove the seeds and the rind — those are the parts that cause problems.
On a hot day, watermelon is one of the most refreshing snacks you can offer a dog. Here's how to serve it safely.
Is watermelon good for dogs?
Watermelon is around 92% water, so it's a light, juicy treat that suits warm weather. It also contains:
- Vitamins A, B6 and C.
- Potassium.
- Antioxidants, including lycopene.
- Very little fat and fewer calories than most fruits.
None of this is essential if your dog eats a complete dog food, but watermelon is a healthier choice than many shop-bought treats, and the low calorie count makes it handy for dogs watching their weight.
The risks
Seeds
Black watermelon seeds are small and hard. A dog who swallows one or two is unlikely to have trouble, but a mouthful of seeds can cause tummy upset or build up into a blockage, and small dogs are at greater risk. Seedless watermelon is the simplest option. The soft, pale seed coats you see in seedless varieties are less of a concern, but pick out any you can easily remove.
Rind
The thick green rind is tough and fibrous. Dogs often try to chew a whole slice, and swallowed chunks of rind can cause vomiting, diarrhoea or an intestinal blockage. Cut the flesh away completely and put rinds in a lidded bin — dogs are good at finding them in bin bags and compost.
Too much at once
Even healthy fruit can upset a dog's stomach in large amounts. Too much watermelon can lead to loose stools, mainly because of the high water and sugar content.
How to prepare watermelon for your dog
- Wash the outside of the fruit before cutting.
- Slice the flesh away from the rind.
- Remove all black seeds.
- Cut into bite-sized cubes, smaller for little dogs.
- Serve fresh, or freeze cubes for a cooling summer treat.
Skip watermelon products made for people, such as fruit salad with grapes, sweets, sorbet or flavoured drinks. These can contain added sugar, artificial sweeteners like xylitol, or toxic fruits. Check our list of foods that are toxic to dogs if you're unsure.
How much watermelon can a dog eat?
Treats should stay under about 10% of your dog's daily calories. Watermelon is low in calories, but it's easy to overdo. As a rough guide, using cubes about 2–3 cm across:
| Dog size | Example breeds | Portion (occasional treat) |
|---|---|---|
| Toy (under 5 kg) | Chihuahua, Pomeranian | 2–3 small cubes |
| Small (5–10 kg) | Shih Tzu, Pug | 3–4 cubes |
| Medium (10–25 kg) | Beagle, Border Collie | 4–5 cubes |
| Large (25–40 kg) | Labrador, German Shepherd | 5–6 cubes |
| Giant (over 40 kg) | Great Dane, Newfoundland | A small handful |
A few times a week is plenty. Check with your vet before offering fruit to a dog with diabetes, as watermelon still contains natural sugar.
Can puppies eat watermelon?
Yes, in small amounts. Puppies can have a few small, seedless pieces once they're eating solid food. Because their stomachs are sensitive, start with one or two pieces and wait a day to see how they get on before offering more. Puppies are also keen to chew anything, so watch them closely around rinds — especially while they're teething. Our puppy teething timeline has safer ideas for sore gums.
Safer alternatives
If watermelon doesn't agree with your dog, other low-calorie options include cucumber slices, peeled mango in small amounts, blueberries and apple slices with the core and seeds removed. Avoid grapes and raisins completely.
Frequently asked questions
Can dogs eat watermelon seeds?
It's best to remove them. One or two swallowed seeds rarely cause trouble in a large dog, but many seeds can cause a blockage, especially in small dogs. Seedless watermelon is the easiest choice.
Can dogs eat watermelon rind?
No. The tough green rind is hard to digest and can cause vomiting, diarrhoea or a blockage if swallowed in large pieces. Don't give your dog a slice to chew.
Is watermelon good for keeping dogs hydrated?
Watermelon is mostly water, so a few chilled pieces can be refreshing on a hot day. It is not a replacement for drinking water — your dog should always have a full bowl available.
