UK to USA Pet Travel
Travelling from the UK to the United States with your pet? Here's what you need to know.

Stage 1
Customs Requirements
Dogs
Most dogs travelling from the UK to the U.S. will typically need:
- CDC Dog Import Form
- Microchip
- Dog must appear healthy upon arrival
- Dog must be at least 6 months old
Some U.S. states may require additional documents or health certificates.
Cats
Federal animal health requirements for pet cats are generally lighter than for dogs. State requirements, airline rules and port-of-entry checks may still apply.
- Microchip recommended
- Healthy on arrival
- Check destination state requirements
Requirements depend on whether you are travelling with a dog or a cat, and which U.S. state you are entering.
