Kristina Hazelett had cats, birds and hamsters while growing up but she never knew much about dogs until she started serving a jail sentence for drug possession. The 35-year-old inmate is part of a team of women prisoners in Phoenix, Arizona who work with the Maricopa County Sheriff's Office Animal Safety Unit (MASH) in a program that comforts and trains mistreated and neglected animals rescued from deplorable conditions. Six days a week the women are transported to the animal shelter in a former men's jail where rows of cells, some adorned with dog portraits and animal murals, have been renamed Bow Wow Way, Purr Lane, 2nd Chance and Ruff Road. "Along the way, we provide the rehabilitation for not just the animals but for the inmates as well," William Sibole, a detention officer with the Maricopa County Sheriff's Office, told Reuters.
