A police officer shot and killed a dog that appeared to be attacking a Pacifica resident's smaller dog Tuesday morning, police said.
Around 9:10 a.m. Tuesday, officers responded to a home on Adobe Drive after a female caller said a loose dog had come into her home through an open door and was attacking her dog, a Corgi, according to police.
When an officer arrived at the home, he saw the homeowner attempting to fend off a dog that was apparently attacking her smaller Corgi, police said.
The bigger dog, possibly a pit bull, chased the Corgi into another room and pinned it to the floor by its throat. The pit bull then released the dog and faced the officer and started at him, police said.
The dog was about 3 or 4 feet away when the officer, apparently fearing for his safety, shot one round of his service pistol at the pit bull, striking it in the chest area.
The dog then died, police said.
Peninsula Humane Society officers also assisted in the investigation and determined that the pit bull and a loose Husky found in the area both belonged to a nearby resident. Humane officers said they would contact the dogs' owner.
The Corgi was taken to an animal hospital to be treated for its injuries suffered during the attack.
Any further action in this case will be handled by the Peninsula Humane Society, police said.
