Roger Chilson decided, for whatever inhumane reason, to leave his dog in an unventilated car. Temperatures had climbed– and authorities suspect that the inside of the car had reached a sweltering 110 degrees.

The 5-year-old Boxer-mix, named Shadow, was left in direct sunlight for approximately 50 minutes, in Geneva, New York, while Chilson went about his business.

The temperature outside the car was around 80 degrees but in direct sunlight, with little to no ventilation, and no way for Shadow to escape, the dog had no chance.

“The temperature of a car goes up incrementally, very rapidly,” Ontario County Humane Society Chief Bill McGuigan told Inside Edition. “A normal dog’s body temperature is around 101, 102 [degrees]. Anything over 103 and a half is life-threatening.”

By the time authorities made it on the scene to assist Shadow, it was too late.

Chilson was arrested and charged with felony aggravated cruelty to an animal. As of Tuesday, Chilson was still in custody of the Ontario County Jail.

Chief McGuigan explains that this tragedy could have been easily avoided. “Leave your pet at home,” he said.”

Time and time again, we are sadly reporting cases like this one. If you see an animal locked inside a hot car, call the authorities immediately. Do not wait and do not attempt to take matters into your own hands. You never know who you’re dealing with.
