Authorities said acts like this are not common, but one Sacramento shelter said it's the second time in two weeks something like this has happened.

"There are friends, there are relatives, there are co-workers and there are shelters" that can take in an unwanted pet, said Gina Knepp of the Front Street Animal Shelter. "There are rescue groups. Dumping an animal that cannot speak or fend for itself is a crime in the state of California."

Police do not have a description of the driver or the vehicle.
