A bit of great news is that the UK is coming into line with other European countries and as from the 1st January 2012 dogs will no longer require passports to go back to Great Britain. No more blood tests or 24/48 hour tick and flea treatments. Your dogs only need to have a valid rabies vaccination of at least three weeks. We are so hoping this will reduce the number of dogs abandoned by Brits leaving France.
