Kevin Doll of the Pasco County Sheriff's Office says 20-month-old Dallas Walters was at his aunt's home during a party Saturday night. Doll says the dog attacked Dallas when the boy dropped a cookie and went to grab it.
Family members at the party managed to pry the dog off the child and then took him to a hospital. The boy later died.
Animal control has taken possession of the dog. Doll said Sunday that the incident is still under investigation, but appeared to be a "tragic accident."
