SARASOTA, Fla. (AP) - A Sarasota County family is warning its neighbors to be on alert after an alligator pounced on their dog and dragged it into a lake.

An alligator killed Darryl Mizer's 50-pound keeshond Noah on Tuesday.

A trapper tried to locate and catch the animal but has not been able to find it.
