Dogs that do not receive adequate hydration during workouts are at risk of suffering from heat stress. Especially during warm, humid weather, it is important to provide frequent water breaks.
It is estimated that a dog’s water requirements may more than double when exercising in warm temperatures. The best way to ensure a dog receives adequate hydration is to give small amounts of water directly from a water bottle every 15 to 20 minutes during exercise.
After exercise, withhold access to clean, cold water until they have calmed down and quit panting. An overanxious dog gulping water can swallow air, causing discomfort or injury to the stomach.
