bull vs pit bull

Seems like the story behind those pictures is really interesting.
Here's Babelfish's opinion:
First picture:

15 September, Phoenix, the state of Alabama. Two pitbulya, which were remained after hurricane without the masters, obtain to themselves food independently.

Last Picture:

Finale histories - dog are shot down.

Wikipedia's opinion on pit bulls (pitbulya??):

Specifically, these dogs accompanied farmers into the fields to assist with bringing dangerous bulls in for breeding, castration, or slaughter.

No wonder the bull was so scared.
