A dog who was rescued by an Ohio animal shelter has a new leash on life as a K-9 officer.Tattoo — a three-month-old, 35-pound Labrador/pitbull mix — last month joined the Swatara Township Police Department in suburban Harrisburg, Pennsylvania.He was rescued from the Franklin County Dog Shelter & Adoption Center near Columbus, Ohio.Tattoo was selected by the therapy K-9 unit of the Franklin County, Ohio, sheriff's office. The therapy dog program trains dogs and their human officers to offer victims "with an outlet from the mental, physical, or psychological effects of experienced trauma," the department's website says.He will be assigned to Swatara school resource Officer Ben Stewart and work mostly in the Steelton-Highspire School District.After Tattoo is trained, his duties will include traumatic incidents, victim forensic interviews, criminal investigations, crisis intervention and medical visits. And he'll also take part in community events. "This therapy K-9 program will assist first responders and all staff within Swatara police with exposure to traumatic events and support efforts aimed at increasing resilience to improve mental health and wellness," Swatara police said in a statement.The pup was named in memory of Christine Stoltz, who served as a Swatara Township police receptionist for the last 25 years. Stoltz died in January."Christine loved tattoos and how they give personal meaning to the people who get them," Swatara police said in a statement. "We believe Tattoo will leave an everlasting impression on every person who he interacts with."
