To prevent your pet from going thirsty, provide two bowls of fresh water and always keep them filled. By training your dog to lick the end of the drip system, you'll always be assured that they'll have enough water. You may want to add ice cubes directly to their water bowls, or freeze a bowl of water for daily use. This technique also works well when taking trips with pets. A Wading Pool filled with an inch or two of water will give pets a pleasant place to cool off.
Dogs often enjoy a cool dip on a warm day.
Dogs often dig holes in yards for the insulating coolness they provide and many times, having a wading pool will keep them from digging holes in your yard to cool off in. It should be big enough for the dog to get in, turn around, and lie down. Your pet supply store can help you get the correct size. Line it with some kind of easily cleaned liner. It should also be fairly small to minimize heat loss in the cold.
