A 60-year-old man suffered life-threatening injuries Wednesday in an attack by his pit bull on Tucson's southwest side, authorities said.
A neighbor reported the attack about 6 p.m. in the 6700 block of South Paseo de las Aguilas, near West Valencia Road and South Camino de la Tierra, said Tracy Koslowski, a Drexel Heights Fire District spokeswoman.
Pima County sheriff's deputies used a Taser to keep the dog under control until Pima Animal Care Center officials arrived, said Deputy Dawn Barkman, a Sheriff's Department spokeswoman.
Fernando Lozano was in his backyard with his stepfather when they heard someone's calls for help, he said. They looked over the fence and saw the dog biting the man. "It literally looked like the dog was eating him," Lozano said.
Lozano and his step- father called 911 and threw rocks at the dog until authorities arrived, he said.
