Animals impounded at Contra Costa Animal Services are held a minimum of 3 business days in order to give an owner the opportunity to find their lost pet. The hold is extended to 5 business days with some form of identification, and 10 business days with their current Contra Costa County license tag. Once the holding period has ended, an animal may be placed for adoption, transferred to another shelter or a rescue group, or euthanized. An animal may be euthanized immediately if the animal is suffering from a serious medical condition or injury and/or is not responding to treatment.
It’s also possible that a Good Samaritan may have found your pet and is keeping them in their own home. Make sure to search the pets found by the public below.
