How do heat and exercise affect the amount of water my dog needs?
Fresh water should be available to your dog at all times to reduce the risk of your dog becoming overheated. Ideally, you should actively offer your dog water during exercise that results in a loss of as little as .5 percent of his body weight. A dog’s need for water increases in keeping with the amount of energy he expends during exercise, and this need may more than double in warm conditions.
