A police officer shot and killed a dog that attacked its owners Wednesday night in northeast Oklahoma City, police reported.

Officer George Goss shot the pit bull terrier at 4207 N Post Road, where Trevonne M. Sango, 26, and Beverleigh Anne Spetter, 26, were both attacked. Spetter suffered bites to her arm and leg, and Sango was bitten on the arm.

Sango said the dog, named Buu, attacked him first. Sango said he got a gun and shot the dog in the back, but it bit into Spetter's arm and wouldn't let go. Sango said he then got a machete and struck the dog to make it let go of her arm. Spetter had to get stitches in her arm.

"He (Buu) wasn't going down and finally we were able to get the dog outside," Sango said, who then called police for help and stayed inside.
