What are the Benefits of Watermelon for Dogs? 

The benefits of watermelon for dogs are listed below.

  • Improves energy: Watermelon can give more energy to dogs thanks to its high sugar levels. One cup of watermelon contains 12 grams of carbohydrates and gives about 52 calories. These are converted into energy necessary for keeping dogs active.
  • Source of hydration: Watermelons are 92% water. This makes it not only an excellent treatment but also an innovative way to keep your dog hydrated, especially during those hot summer days. Feeding watermelon to a dog that doesn’t fancy drinking water can help keep it hydrated.
  • Boosts immunity: Watermelons are rich in vitamins A and C plus antioxidants like lycopene which help combat free radicals that cause cell destruction leading to an improved immune system. Good immune health is essential for improving the overall well-being of dogs.
  • Improves digestion: Watermelons have moderate amounts of fiber. This is necessary to promote gut health in dogs and facilitate the smooth flow of food through the intestinal tract. This prevents constipation and other digestive issues such as diarrhea.
  • Promotes eye health: Watermelon contains beta carotene, which is turned into vitamin A by the dog’s body. Vitamin A, in addition to lycopene, which is abundant in watermelon, helps improve vision in dogs.
  • Supports kidney and heart health: Watermelon has minerals such as potassium and magnesium, which aids in the proper functioning of a dog’s heart and kidneys.
  • Improves skin and coat health: Due to their high hydrating power, watermelons can help keep dogs’ skin well moisturized and supple. Vitamin B6, also present in watermelon, is crucial for maintaining a healthy coat in dogs.

What are the Harms of Watermelon for Dogs? 

Although watermelon is generally safe for dogs, it may cause some harm to dogs in some circumstances.

The harms of Watermelon for dogs are listed below.

  • Stomach upset: Like any other thing, too much of a good thing can also cause health problems. As such, feeding too much watermelon to dogs may result in them getting tummy upsets.
  • Choking/ Intestinal Obstruction: Although the watermelon rind is not toxic to dogs, its hard texture makes it extremely hard for dogs to break it down.

Swallowing too many hard watermelon seeds can also cause stomach upset or intestinal obstruction, especially in small dogs.
  • Obesity/ Diabetes: Watermelons are high in sugar, leading to unhealthy weight gain and consequently obesity or diabetes if fed excessively to dogs. Always consult a vet before feeding these fruits to dogs with diabetes as it may worsen the condition.
