PLEASANT HILL -- A 38-year-old woman was arrested Friday after her dog died when she left it inside a locked car in sweltering heat, police said.

Around 4:04 p.m., officers responded to the city's downtown parking structure, located at 160 Crescent Drive, for calls of a dog in distress. The city was reaching its high temperature for the day -- 101 degrees -- around the same time, according to web site Weather.com.

Police found the dog, a boxer, was locked inside the vehicle with insufficient ventilation. The responding officer forced his way into the car and grabbed the dog.

Officers immediately took the dog to a nearby veterinary hospital, but it died.

Police met with the dog's owner, 38-year-old Angela Kleinfeld, at the parking structure, and took her into custody. She was held on suspicion of cruelty to animals resulting in death.

Officials warn pet owners and parents that extreme weather like the high temperatures seen this week can quickly turn fatal for animals or children left inside vehicles. Even in more moderate temperatures, a car's internal temperature can shoot far past 100 degrees.
