The dog is described as a 60-pound, intact male American pit bull terrier who is about a year old, police said.
"He has scars on his neck and face and beautiful light-colored eyes," police said.
Police are trying to locate his owner, but the dog may be available for adoption in two weeks if no one has come forward to claim him, police said.
