Brookfield Zoo officials said Monday they're not doing anything differently after African wild dogs attacked and killed a toddler at a Pittsburgh zoo over the weekend.
Still, officials said they often take a second look at their own procedures as events warrant.
"We have, like all other accredited institutions, procedures and policies that we follow in the event of an accident -- even a person having a heart attack -- and we also drill on those events too," said Bill Zeigler, the Brookfield Zoo's Senior Vice President of Collections and Animal Programs.
A 2-year-old boy on Sunday fell into an African painted dog exhibit at the Pittsburgh Zoo. The boy's mother put him on a railing to view the animals, officials said, and the boy fell 11 feet and was attacked by the dogs.
He said a fence and a moat system helps prevent visitors from falling in.
