DICKSON CITY — A national pet store chain said it’s investigating the death of a dog that was attacked in the grooming area of one of its Pennsylvania stores.

Betty Miller of Scranton told a TV station that she dropped off her dog, a 12-year-old Bichon named Brewster, at a PetSmart in Dickson City to get groomed. A short time later, she said a vet called to let her know that Brewster had been killed in an attack by another dog.

Miller said the attacker was a pit bull. She said she doesn’t understand how the store allowed the dog to come near her pet. She said Brewster was “bait” for the other dog.

PetSmart said it’s “truly saddened” by the incident and is investigating whether there were any violations of its procedures.
