Can Dogs Eat Watermelon?
Yes. Watermelon is one of the safest fruits for dogs: it's 92% water and low in calories. Serve it without the seeds and without the rind.
What it gives your dog
Watermelon has very few calories (about 30 kcal per 100 g), lots of water, and some vitamin A, vitamin C, potassium and lycopene. In summer it's a refreshing treat that also helps your dog take in a bit more fluid, which is useful for dogs that don't drink much.
What you need to avoid are the seeds and the rind. The black seeds aren't toxic, but many at once can irritate the gut or, in small dogs, contribute to a blockage. The green rind is hard, digests poorly and can cause vomiting or get stuck if swallowed in large pieces. “Seedless” watermelons still have the white seeds, which are soft and don't usually cause problems.
How to serve it
- No rind and no black seeds
- In bite-size cubes
- Frozen in cubes or blended into homemade ice cream
- Chilled from the fridge, rather than straight from the freezer for very small dogs
How much can they eat?
Small dog (under 10 kg / 22 lb): 2-3 cubes (about 50 g / 2 oz). Medium (10-25 kg / 22-55 lb): about 100 g (2/3 cup diced). Large (over 25 kg / 55 lb): 150-200 g (1-1 1/3 cups diced). It's low in calories, but a lot at once can cause diarrhea; keep it within the 10% for extras.
Risks
- Rind: vomiting or blockage
- Black seeds in large amounts
- Diarrhea if they eat a lot
- Salted watermelon, watermelon candy or sugary watermelon drinks
Frequently asked questions
Can my dog eat watermelon rind?
Better not. The rind isn't toxic, but it's hard and fibrous, and many dogs swallow it in big pieces without chewing. It can cause vomiting, diarrhea or, at worst, an intestinal blockage. If you like giving your dog something to gnaw on, offer a toy or a treat designed for chewing.
Is watermelon good for dogs in hot weather?
Yes, it's one of the best summer options: it's 92% water and low in calories, so it cools them down and adds fluid. Offer it in chilled cubes or frozen. That said, it doesn't replace fresh water and shade, and it won't treat heatstroke, which is an emergency.
What happens if my dog eats watermelon seeds?
A few seeds don't usually cause anything: they aren't toxic and pass in the stool. The risk comes if your dog eats a lot, especially small dogs, because they can irritate the gut or contribute to a blockage. Watch for vomiting, not eating or not pooping, and if you see any of these, talk to your vet.
