The Central Oregon Humane Society says extra precautions are necessary for your pets during this current heat wave. If your pet is outside during the day, remember to provide plenty of fresh water and protection from the sun. Remember that older, short muzzle and overweight dogs are more likely to overheat during hot weather. One way to keep them cool is to provide a wading pool to aid in cooling. Leaving your pet in a parked car can be a deadly mistake. The temperature inside a car can reach 120 degrees in a few minutes.
