When we lived in the Montignac area of the Dordogne running our luxury camping a la ferme, it was amazing how many dog (and cat) owners we had who used to worry and fret away their holidays thinking about their return journeys and the dreaded vets visits they would have to be making. The result of this was that we made blanket arrangements at vets in both Montignac and Terrasson - Lavilledieu where our clients would simply go along and present them with an introductory card (if they only had poor French) and get the job done. After all, even though Calais was some 550 miles away, they did have up to 5 days to get there........... As such, chill out, relax and enjoy your holidays.
