Keep pet water cool by adding ice chips or cubes to the dishes of smaller pets and ice blocks for larger animals. Ice blocks can be made easily by freezing water in used food tubs.

Cats and dogs may also appreciate a frozen treat. Freeze no- or low-sodium broth in ice-cube trays -- and offer them the cubes outside to minimize any mess. You can also find commercial frozen treats for pets, such as Ice Pups (from The Honest Kitchen) or Frosty Paws.

Be sure your pet is always kept supplied with lots of clean water. For caged pets, check to be sure that the delivery tube of a water bottle isn't clogged, blocking the flow of water. For other animals, don't just add clean water on top of dirty in a filthy bowl -- scrub and refill the dish at least once a day.
