On summer afternoons, when dogs stick out their tongues and lie on the floor, we can't help but want to give them some cool fruits to cool them down. Watermelon, as a "natural hydration tool" with a moisture content of up to 92%, has naturally become the choice of many homeowners. But in the face of the dog's eager gaze, we inevitably have doubts: is this sweet gift really safe?
From a nutritional perspective, watermelon does contain beneficial ingredients for dogs. Every 100 grams of watermelon contains 46 calories, rich in vitamin C (to enhance immunity), lycopene (antioxidant), and citrulline (to promote blood circulation). For elderly dogs or dogs with joint discomfort, the natural moisture in watermelon can reduce the burden on the kidneys, while potassium helps maintain electrolyte balance. The American Veterinary Association (AVMA) has published research indicating that moderate intake of watermelon can serve as a low calorie snack substitute for obese dogs.
However, there are hidden risks behind the sweetness. The glycemic index (GI) of watermelon is as high as 72, making it a high sugar fruit. Excessive intake may lead to blood sugar fluctuations in dogs, especially in dogs with diabetes. A case report in the Journal of Small Animal Medicine in 2023 showed that a 12-year-old poodle suffered from ketoacidosis after stealing watermelon for three consecutive days. In addition, the high moisture content of watermelon may cause diarrhea, especially in puppies or dogs with sensitive digestive systems, and their intake should be strictly controlled.
The handling of watermelon seeds and skin is crucial. Although watermelon seeds are small, consuming them in large quantities may clog the intestines. I once treated a Schnauzer, but due to its owner feeding a watermelon with seeds, it caused intestinal obstruction. Eventually, 47 seeds were removed through surgery. The fruit peel contains cucurbitacin, and excessive intake may cause vomiting and abdominal pain. The correct approach is to completely remove all seeds, cut the flesh into small pieces of 1-2 centimeters, and remove the skin.
Special dog breeds require extra caution. Watermelon should be completely avoided in diabetes dogs and pancreatitis recovery dogs. Obese dogs should be strictly limited (no more than 50 grams/10 kilograms of body weight per day). Short nosed dog breeds such as bulldogs are prone to stomach torsion, so it is recommended to feed them in small amounts in small portions. The digestive system of puppies is not yet fully developed. The first attempt should be observed for 24 hours to confirm that there are no adverse reactions before continuing.
Scientific feeding is the key to combining deliciousness and safety. Choose ripe watermelon (high sweetness means good maturity and less harmful substances), and rinse the surface with clean water for pesticide residues. Suggest feeding as a reward between two meals to avoid affecting the appetite for the main meal. Paired with yogurt or probiotics, it helps regulate the gut microbiota. Prepare pet wipes and promptly clean the juice from the dog's mouth to prevent bacterial growth.
When we watch dogs happily lick watermelons, the pure joy is so touching. But there needs to be a rational boundary between love and indulgence. Careful checks before each feeding and firm decisions to control portions are the best response to this trust. May every dog enjoy the coolness of summer in safety and happiness, touching the beauty of life with its wet nose tip. After all, true love is knowing how to protect its health and smile.
