In the days prior to your animal's departure it is a 
good idea to get your pet used to its traveling container.
 Let it wander in and out and sleep in there if it likes. 
On the day of the flight only feed the animal a small meal 
(if at all) but if it requires a special diet make sure a supply 
is attached securely to the box. A dog will appreciate a 
good walk before being confined but we do not recommend 
sedating your pet unless absolutely necessary due to the 
unpredictable results.

For your peace of mind you can now complete your own checklist prior to your pet traveling. This will ensure that you have covered all the essential requirements for your pet to enter the UK. Please note that we will complete the official checklist on arrival at Manchester and that our decision (in conjunction) with DEFRA is final. Please click on the relevant link below and the checklist will appear in a new window.
