Important Notes
- A physical ID Card, Registration Certificate, and visible Recognition Gear speed up the processing.
- No airport restrictions: You do not need to enter through a special CDC-approved airport. You can enter at any U.S. airport as long as the airline accepts the animal and you have the required documents in your possession.
- Assistance Animals follow the same import rules as pets.
Deworming / Tapeworm Treatment Rules
California does not require tapeworm or deworming treatment for entry.
Routine deworming is recommended due to the high presence of wildlife and outdoor activity regions but is not mandatory for arrival.
Restricted Breeds at Entry
California has no statewide breed restrictions.
However, many municipalities have “dangerous dog” ordinances that may affect Pit Bull–type breeds. These rules vary by county or city and are not general bans.
Public Transport & Transit Rules
Service Dogs are allowed on all public transportation, including BART, LA Metro, Muni, and regional bus systems.
ESAs and pets are typically not allowed unless in carriers and subject to each transit system’s policies.
