Justin Peggs was working off a 45-day sentence for assault at the Cape May County Animal Shelter and Adoption Center in Middle Township when the dog sank its teeth into Kathleen James' thigh.
James told The Press of Atlantic City the 22-year-old heard her cries and jumped on the dog and held it down until the staff could subdue it.
James needed stitches and the dog was euthanized.
Peggs is participating in the Sheriff Labor Assistance Program, which allows him to complete his jail time by working nights or weekends for the county.
