Underdogs(2008)

Overview:

In Brunnenberg prison for men, the new warden introduces a revolutionary convict re-socializing project: training guide dogs for the blind. The perks make all convicts volunteer for only seven slots. Except burly macho Moskowitch 'Mosk', who cares only for the manly work out contest. The warden blackmails him, he can only do the contest if his assigned pup passes the first test. All dogs must pass or the project is halted. Unlike the others, Mosk only starts caring for his canine when it gets sick.
