A police dog with the Mendocino County Sheriff's Office died Saturday after jumping off a roof, authorities said.

The dog, Argus, escaped from an enclosed backyard and somehow climbed up onto a nearby structure, Sheriff's Lt. Shannon Barney said.

The dog apparently leaped off the building after its handler, Deputy Craig Walker, called out to him at about 11:45 a.m. Saturday, Barney said.

"It appeared Argus responded immediately to his handler's call and was not aware of the height of the structure he was on," Barney said in a statement.

The dog fell about 30 feet and died on impact, Barney said.

The 2-year-old German shepherd, originally from Slovakia, had worked with Walker, who patrols Anderson Valley, for about six months. Barney said plans are to replace the dog.
