Make sure your dog drinks enough water. If you are in the sun with your dog, you should also provide cool places to retreat to. If you are on the beach with your dog, you can rent a beach chair or take a beach tent with you. A damp towel will also help cool your dog down. An additional cooling vest protects against UV rays and offers your dog a pleasant refreshment. In hot weather, it is best to go for a walk early in the morning and late in the evening. This will protect your dog's paws from the heated asphalt.
