Taking your new dog on holiday to Europe with you is easy provided you can drive to your destination. It just takes a little planning ahead. Firstly, your dog should be microchipped. It is the law in the UK that all dogs over 8 weeks old should be microchipped so you should be good to go here. Next you will need a Pet Passport and a rabies injection. Your vet can supply both at the same time. Make sure you do it at least 21 days before you intend to return to the UK.
When you set off, don’t forget to take your dog’s passport as well as your own! At the port they will ask for the dog’s passport and will ask you to run the scanner over the microchip. Try to get your dog to empty his/her bowels and bladder while you wait in the car park to board. Once on board the dog will not be allowed on the upper decks, and passengers may not remain on the car deck, so he/she must be left alone in the car. Provide a favourite toy, water bowl and perhaps some dog biscuits. Make sure the ventilation is adequate. On a warm day it may be a good idea to have a cooling pad like this:
I can’t speak for the rest of Europe because we have only taken our dog to France. In France dogs are much more welcome in hotels and restaurants there than they are in the UK.
One extra thing to remember when you are preparing to return. You must visit a vet for a tapeworm treatment (a tablet) between one and five days before your scheduled arrival time in the UK. Forget this and your new dog won’t be allowed back in the country!
