Maryland's prison agency says it's expanding an inmate dog-training program at the Roxbury Correctional Institution near Hagerstown.
Department of Public Safety and Correctional Services spokesman Gerard Shields says state Sen. Andrew Serafini is helping to announce the program Friday at the prison.
Shields says the Happy Hounds program allows inmates to train rescued shelter dogs for adoption. He says it's expanding from six dogs to 10.
Warden Richard Miller says in a statement that training the dogs gives inmates a sense of accomplishment.
Shields says the program has been run at the institution since 2011. It is supported by Uniting to Save Animals, based in neighboring Frederick County.
A number of other Maryland prisons also have dog-training programs.
