Officers were called to 88th Street near Third Avenue on Saturday after a passerby noticed that the dog had been left in the car with its window up for more than two hours.
The dog appeared to be in distress.
Officers broke a window so they could open the door and get the dog out. It was taken to a veterinarian for care.
A 26-year-old man was charged with animal cruelty.
Police are reminding people that it only takes 10 minutes during an 85-degree day for the inside of a car to reach 102 degrees.
