A boy has died after falling into an enclosure at Pittsburgh zoo and being mauled by African painted dogs.
Tracy Gray, of the Pittsburgh Zoo and PPG Aquarium, said it is not clear whether the boy died from the fall or the attack.
Zoo president and CEO Barbara Baker said the boy, who was about three, fell 14 feet. She said there were 11 dogs in the enclosure and some attacked him.
The dogs are about as big as medium-sized domestic dogs, 2 to 2½ feet high and weighing 37 to 80 pounds. They are considered endangered.
In May, some of the dogs escaped into a part of the enclosure that is usually closed. The zoo was shut down for about an hour as a precaution.
