World's deadliest breed is at it again.....

Boston (WCVB/CNN) - A Massachusetts pit bull saved her owner from an oncoming freight train, risking life and limb, to pull her off the tracks.

The woman survived, but the dog is severely injured.

David Lanteigne has adored this pit bull since recuing Lilly from a shelter to be a companion for his mom who suffers from alcoholism.

"We saved her life and she saved my mom's life," he said.

It was midnight last Wednesday when his mom fell unconscious on train tracks in Shirley.

"Lilly was either pushing or pulling my mother off the tracks," said Lanteigne. "There wasn't enough time and that just prior to the train making impact Lilly had intentionally gotten between the train and my mother and had taken the hit."

The entire hit. Eight-year-old Lilly suffered severe trauma. David's mother was uninjured.

[Reporter]: "Will this dog be able to walk again?"

"Yes she should be able to walk quite well. They accommodate quite well to having a front limb amputation," said the veterinarian.

Lanteigne, a Boston police officer, will be with her every step of the way.

"I'm supposed to be the strong one. I'm supposed to be here for her, but she's been so great, so tough through all this. It almost seems like she's the one comforting me and being there for me and making me feel better," he said.

I'm trying to wrap my head around how the dog got hit, but the owner didn't. If the dog was "pulling", then it would be off the track pulling the person off. I've never in my life seen a dog try to push anything (other than giant terds out on my lawn). Something's fishy.

After getting its owner off of the tracks, the dog tried to defend her against the train and got between the two of them.

"fell unconscious" (i.e. drunk off her ass), then where are these facts coming from?
