If these dogs are coming to the UK from the US, your information is completely wrong the dog will not appear with your baggage. At Heathrow, the animal will be taken by the carrier's handling agent to the Animal Holding Centre located a mile from T4. At Gatwick, it will be taken to the BAWC animal centre - either way will be held there pending formalities and subject to acceptance under the Pets Passport scheme, be available for collection 2-3 hrs after arrival of aircraft.
