The Genius Gadget You Need to Keep Your Dog Cool All Summer Long

The Te-Wai FreeZone Dog Pet Water Bowl Freeze Cool & Frosty Foldable Portable Bowl ($19) not only keeps your dog's water cool for up to six hours (it uses the same freeze technology other bowls in this list utilize), but it folds up into a cold-insulated pouch that turns into a cooling collar for large dogs (if your dog is small, you'll have to carry the pouch). The bowl holds up to 50 ounces of liquid and is made of FDA-approved silicone.
