Quick answer
  • Yes, dogs can eat watermelon
  • Remove the seeds and rind
  • Refreshing in summer: it is 92% water

Yes: watermelon is one of the best summer snacks among the fruits and vegetables for dogs. With 92% water content, it helps with hydration on hot days. Always remove the seeds, and never feed the rind.

What watermelon offers dogs

Watermelon contains lycopene, a powerful antioxidant that is also found in tomatoes and protects cells from free radicals. On top of that come vitamins A, B6 and C as well as potassium. At around 30 calories per 100 g, watermelon is very low in calories, which is good for overweight dogs.

What to watch out for

Always remove the seeds completely: they can lead to diarrhea or, in the worst case, an intestinal blockage. Seedless watermelon is more practical here.

The green rind is hard to digest and can cause stomach and intestinal problems: only feed the red flesh.

How to feed watermelon

Peel the watermelon, remove all the seeds and cut it into small pieces. Serve it plain as a snack or frozen as a summer treat. Freeze watermelon puree in ice cube trays for handy portions on hot days.

Nutritional values and amount

100 g of watermelon (flesh) contains about 30 kcal, 0.6 g protein, 7.6 g carbohydrates, 0.4 g fiber and 8.1 mg vitamin C. The 92% water content makes it one of the lowest-calorie fruits. 100 g provides about 4,500 mcg of lycopene.

Guideline by body weight (flesh without seeds and rind):

  • Small dogs (up to 10 kg): 2 to 3 small pieces (about 50 g)
  • Medium dogs (10 to 25 kg): 4 to 6 pieces (about 100 g)
  • Large dogs (over 25 kg): up to 150 g

Cut the watermelon into bite-sized cubes and serve it chilled. For ice cube treats, freeze pureed flesh in silicone molds. On hot days it is a good addition to your dog's water intake, but it does not replace the drinking bowl.

Frequently Asked Questions

Can watermelon improve hydration in dogs?

Yes. With 92% water content, watermelon is especially good for topping up fluids on hot days. It is no replacement for fresh drinking water, but it is a useful addition.

Are watermelon seeds dangerous for dogs?

Some seeds can cause digestive problems or contribute to an intestinal blockage in small dogs. Always use seedless watermelon or carefully remove every seed.

Can my dog eat frozen watermelon?

Yes, frozen watermelon pieces without seeds and rind are a very popular summer treat. Freezing barely changes the nutrients.

How much watermelon can a dog eat per day?

A few pieces as a snack. Despite its low calorie content, watermelon contains fruit sugar, so too much at once can cause loose stools. For small dogs 2 to 3 pieces, for large dogs correspondingly more.
