I always make sure Keeda has fresh water. Because she has a doggie door and access to one of the rooms in the house she can just go into the air conditioning when she gets too hot. We take some precautions when exercising in the heat, though. Keeda doesn't deal very well with hot weather, she gets tired more than twice as quickly as she does in cool weather. I actually even wrote a post about exercising dogs in the heat recently.
