Just last week, they were "in the pen".
Now, three adopted dogs are training to police jail cells.
The three canines left the Humane Society to take part in a correctional work dog program.
For two months, the German shepherd and two labs will work at the Indiana State Prison in Michigan City.
Then, they will move to a medium security prison in southern Indiana.
Indiana State Prison Superintendent, Ed Buss, stated, "It depends on the dog and the work that they do. If they do aggression work they shepherd’s normally last 4-5 years. The labs can last as long as 10 years before they retire."
Humane Society officials say it is a great opportunity for the three pups.
Once waiting for adoption, they will now get attention 24-hours a day.
