Why Water & Hydration Matters

Water is the single most important nutrient for dogs, making up 60-80% of their body weight. Proper hydration is essential for digestion, temperature regulation, waste elimination, and every cellular process. Dehydration can become life-threatening within hours, especially in hot weather or active dogs.
