Rabies antibody titer test (≥ 0.5 IU/ml)
Because the USA is not EU-listed, your dog must pass a rabies antibody blood test showing a level of at least 0.5 IU/ml. The blood sample must be taken at least 30 days after the rabies vaccination. After the blood sample is taken, you must wait 3 months (90 days) before travelling to Great Britain. The test must be carried out by an approved laboratory.
