This is why i brought the subject up , I paid €39 in Pontorson , i knew I was being ripped off but did not know any better ,its best to have your dog tic treated before you go (treatment can be bought in supermarkets here ) as there can be some nasty ones abroad , on way home your dog must have worm treatment 120 to 24 hours before departure witnessed on passport by vet ( i think you can supply your own tablets ) and ferry companys like you to check dogs in at terminal building as its time consuming at car check -in point and causes boarding delays
