From Bev Farmer of Podenco Friends.

‘Potentially big changes for taking your pets overseas from the UK after March 2019… It could resort back to the old system where titre counts for Rabies are required and 4 months waiting before they can travel and to complete a number of documents to travel. We had to do this back in 2001 when we first moved to Spain with our dogs. This will also impact on rescue dogs though in this article there is no mention of them but I imagine they will have to comply with the same rules to travel from Europe to the UK.’
