ST. LOUIS (AP) — The St. Louis Circuit Attorney’s office is deciding whether charges should be filed against a dog owner who left a Chihuahua inside an SUV on a scorching hot day.

The Missouri Humane Society’s Animal Cruelty Task Force on Tuesday rescued the dog outside the St. Louis Zoo. KMOV-TV  reports that someone passing by saw the dog in a Ford Explorer that was parked in the sun on a day when the air temperature was in the upper 90s. The Humane Society says the dog was panting and appeared to be in distress.

The dog was taken to Humane Society headquarters and examined, and was determined to be unharmed.
