A new member with four paws joined the Suffolk County Sheriff's Office on Tuesday.

Luna, who is named after fallen FDNY firefighter Billy Moon, is training to be a certified therapy dog. When she is fully trained in around 8 to 10 months, the pup will do something to honor the man who she is named after.

"First responders, law enforcement, they are selfless jobs," says Billy Moon's widow, Kristina Moon. "To know that there is a dog named after him that honors that legacy and the understanding of how hard that work is and how important it is to support those people is really nice."

Luna was donated by Paws of War and is the first therapy dog to join the ranks at the Suffolk County Sheriff's Office, where she will work alongside the wellness unit.

Those within the department believe Luna will help foster a safe environment and improve the mood of employees.

"We realize our staff are going through a lot," says Suffolk County Sheriff Errol D. Toulon.

Once Luna gets her certification, she will be brought to the deputy command corrections facilities as a jump-off point.
