A Westchester police officer shot and killed a dog after being attacked late last week.

The officer was responding to a call from a Westchester firefigher that a dog was growling and chasing people at about 2:30 p.m. Aug. 8 on Mayfair Avenue, near the Mayfair Fire Station at 10760 Cermak Road in Westchester, according to police reports.

Police said the firefighter was riding in a department vehicle when he saw the boxer-shepherd mix, weighing about 45 pounds, running loose across the street from its owners’ home on the 2100 block of Mayfair Avenue. The firefighter exited the vehicle to notify the owners, but the dog growled and chased him back into the vehicle, where the firefighter called police.

While waiting for police to arrive, the firefighter saw a woman exit a nearby home and try to cross the street when the dog growled and pursued her, according to reports. The firefighter then sounded the vehicle’s siren to distract the dog, and the dog ran back to its owner’s driveway.

When the firefighter tried to exit his vehicle a second time, the dog again charged at him and chased him back, police said.

According to reports, a police officer then arrived and was heading to the car’s trunk to grab a tool to noose loose dogs. Before he reached the trunk, however, the dog jumped at the officer.

The officer put up his gloved right hand, and the dog grabbed onto it, knocking the officer down. While falling, the officer shot at the dog, which continued to attack, biting through the officer’s glove and pulling it off, police said. The officer then fired a few more rounds, killing the dog.

The dog’s body was taken to the Hillchester Animal Hospital for testing, and the officer was treated and released at Loyola Hospital in Maywood for bite wounds to his hand, according to police.

Police discovered later that the dog owner’s fence around the yard was broken, and the owners, a 13-year-old boy and his father, were not home, according to reports. A grandmother visiting the home told police she was afraid of the dog and could not get it to enter the house.

Scott Holis, 52, 2120 Mayfair Ave., was cited for dog at large and no dog tags displayed.
