A rottweiler attacked and killed a Florida toddler when the boy reached to pick up a cookie he had dropped, authorities said.

Kevin Doll of the Pasco County Sheriff's Office said 20-month-old Dallas Walters was at his aunt's home during a party Saturday night. Doll said 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.
