(CNN) Coming forward to report a sexual assault can be painful and emotionally exhausting. For children and people with developmental disabilities, retelling their stories can be especially confusing.

That's why the Cook County State's Attorney's Office in Chicago hired its first comfort dog, a black Labrador retriever named Hatty.

"We're excited to welcome Hatty to our team where she will provide comfort and peace to victims during one of the most difficult times in their lives," said Cook County State's Attorney Kim Foxx.

Hatty will take on up to 200 cases every year.

Two-year-old Hatty was sworn in on Tuesday, standing on her hind legs and placing one black paw across a law book as an oath was read.

Hatty's job will be to assist children and developmentally disabled victims of sexual trauma, an official press release said. Hatty will be there for the victims while they testify in court, as well as during interviews with prosecutors and officials.
