Jimmie Belchick of Carnegie said Cobain, his American pit bull terrier, a breed often in the news for attacking people, found the woman crumpled against a grate at the bottom of a ditch about 1 p.m. Saturday and quickly ran to alert his master, WTAE-TV, Pittsburgh, reported Tuesday.
"My dog put Lassie to shame. He came and alerted me when somebody needed help and what more can you ask for out of your dog," Belchick said.
Belchick said the woman appeared weak and had trouble speaking. She was taken to Allegheny General Hospital, where paramedics said she is expected to be fine.
Belchick said he is proud of Cobain for acting fast.
"He's one in a million. I tell him that every day, but now, that's some proof right there," Belchick said.
