BELLEVUE - It doesn't take record breaking heat to cause problems for pets left inside of a car. In fact even on cool, overcast days, pets are still at risk because the inside of cars heat about 30 degrees hotter than the outside temperature.

Dr Mark O'hanlon owns the Emergency Animal Clinic in Kirkland and tells Q13 FOX News, "They don't have the ability to sweat. They don't have the ability to radiate heat that way that humans do." He recommends keeping pets out of the car completely, no matter what the temperature is outside.

In the past two weeks, two dogs have died after over-heating inside of a car. This according to Sarah Sage, a Bellevue Vet Tech, who says "Both dogs have been over 110 (degrees)and have died on the table. So it's more extreme this year than I've seen in previous years."

The long range forecast call for much of July and August to be hotter than average and with pets expected to be outdoors getting some exercise, Dr. O'hanlon gives some warning signs of heat stroke."Excessive panting. Drooling. Lethargy or not willing to exercise or move are probably the most common warning signs," said O'Hanlon.

He adds the best way to keep pets cool is with a fan or cool towels. And to limit the amount of time they spend outdoors getting heated. He cautions, "Your dog loves you and he wants to go chase the ball forever. They will literally chase the ball until they drop over dead sometimes."
