Will I still be able to take my pet on holiday with me after October 2019?
Yes. After 31st October 2019, you will still be able to travel with your pet (dog, cat or ferret) to Great Britain whether a deal is reached or not. However, in a no-deal scenario, you may need to take some additional steps depending on how the UK is categorised from 31st October 2019. Importantly, you may need to visit a vet some months in advance of travel, for certification and relevant vaccines. More information can be found on the Government's pages about Pet travel to Britain after Brexit.
The above Q&A is based on latest government advice which may be subject to change.
