When they arrived, they entered and found the dog in a bedroom, said Garden Grove Lt. Carl Whitney.
The officers deployed a fire extinguisher and an animal control pole to control the dog, Whitney said in a statement. It charged at officers and tried to bite one.
"One officer fired several rounds that struck the animal," Whitney said.
Officers then finished the search of the house and found narcotics, weapons, ammunition and stolen police equipment, police said.
"When officers discharge their weapons at animals, an internal investigation is conducted to review the facts of the shooting," Whitney said. "Investigators will work with (the county's) animal control services for this investigation."
It was unknown if the dog belonged to Pudiquet.
