Why is this (door to door canvassing) happening suddenly out of nowhere? Animal Care Services (formally Animal Control) has had a license canvassing program since the 1960's. The recent media exposure may just be bringing it to the attention of more and more residents. It is estimated that there are over 225,000 household cats and dogs in the City of Long Beach that must be vaccinated against rabies and licensed with the City. Door to door canvassing is really an inexpensive way for us to ensure residents are responsible pet owners and allows us to promote public health and safety. Remember licensing and microchipping are the only real ways we can successfully return lost pets to their owners.
