She swam across a 12-foot-wide moat to the interior of the exhibit and was quickly attacked by a 225-pound female Sumatran tiger.
Zoo workers used fireworks and air horns to distract the two tigers in the exhibit and get them into their night enclosures behind the exhibit viewing area.
After emergency treatment by zoo veterinarians, the dog was taken to the Animal Emergency Medical Center in Memphis where she was reported in good condition Wednesday.
