Crate Toolsclip-on cooling fan ($14.52). If you have to spend a lot of time in the sun, consider throwing on a solar canopy ($22 for 6x6); its space-age material will deflect light and heat from the crate below.
Water FountainThe Pioneer Ceramic Drinking Fountain ($45.95, large) is an attractive way to keep the water flowing. We also love the Drinkwell 360.
Cooling MatThese cooling mats ($30.99) are filled with a material that becomes gel-like when filled with water, which absorbs heat; between that and an electric fan, your dog can withstand just about anything the sun is throwing at it. You can also buy vests full of the same stuff.
ASPCA Weather App for iOS and Androida free app for iOS and Android that gives you a 3-day, pet-specific forecast, so you'll know if Fido can safely walk outside or if you should pack extra water.
