The female dog, a 6-month-old shepherd mix named Karley, allegedly was beaten by a neighbor, Los Angeles County Assistant Fire Chief Glynn Johnson, who was placed on administrative leave Friday while the incident is investigated.

Johnson reportedly told investigators that he had acted in self-defense.

Karley was euthanized a few hours after the incident, which occurred about 4:30 p.m. Monday.

Karley apparently had run across Johnson's yard and into the next yard.

Travis Staggs said he started walking the dog home from his yard when Johnson offered to take Karley home.

"Then something in his head snapped and he started beating the dog," Staggs said.

Johnson allegedly punched Karley with a closed fist about a dozen times and then beat her with an 11-inch rock, Staggs said, adding that he tried to stop Johnson but was pushed away.

Authorities received two calls from the 17000 block of Armintrout Drive: one from a woman who said her husband was attacked by a dog, and another from a man who said his neighbor had beaten a dog, Riverside County Sheriff's Sgt. David Barton said in a statement.

After Brandon Toole, 19, saw the injured dog, his 17-year-old sister, Heather, rushed the animal to a veterinarian, and later an animal intensive care unit.

Karley was euthanized because she was so badly injured, said Jeff Toole, the teenagers' father.

Police said Johnson was taken to a hospital for wrist and thumb injuries.

Jeff Toole said the thumb puncture occurred when Johnson grabbed Karley's mouth and broke her jaw.



Full statement from Los Angeles County Fire Chief P. Michael Freeman:

"The Los Angeles County Fire Department is deeply concerned with allegations regarding Assistant Fire Chief Glynn Johnson's actions in the beating of his neighbor's dog. Prior to the news reports, Chief Johnson had advised his superiors of the incident and explained his actions as self-defense.

Given the nature of the allegations and the ongoing Riverside County Sheriff's investigation, Chief Johnson has been placed on administrative leave (with pay). Once more facts are available, the Department will take appropriate action as warranted.

There will be no further information available by the Department until the investigation is completed"
