Hydration and dehydration prevention for humans and pets

Maintaining hydration is critical during high temperatures, both for humans and pets. For people, early signs of dehydration can be subtle and include dark yellow urine, headaches, fatigue, dizziness, and muscle cramps. A simple skin elasticity test—pinching the skin on the back of the hand to see how quickly it returns to its original position—can help identify fluid loss.

In addition to drinking water, approximately 20% of fluid intake can come from food, a concept sometimes referred to as ‘chewing water’. High-water-content foods such as watermelon (over 90% water), cucumber (95-96% water), tomatoes, melon, celery, and strawberries are highly effective for hydration. These foods also provide essential vitamins, minerals, and electrolytes like potassium.

Veterinarians warn that pets, particularly puppies, kittens, and active animals, are highly susceptible to dehydration. Signs in animals include lethargy, dry or sticky gums, and skin that does not snap back quickly when lifted. Owners are advised to provide fresh water constantly and seek veterinary help if symptoms like vomiting or extreme weakness occur.
