Can I ask which ferry operator
you were looking at? If you're looking to get a direct ferry to Ireland from Cherbourg, both companies servicing this route - Irish Ferries
and Stena Line
- should allow you to take your dog along with you. I'd recommend reaching out to them directly for detailed information if you're unable to make a booking bringing your dog along.
There's some practical information
about bringing your furry friend to the island you might want to have a look at as well. They'll need a Pet Passport and a tapeworm treatment before travelling to Ireland.
I hope you'll be able to get it sorted, so the two of you can soon both enjoy a fresh Atlantic breeze on your faces. :)🐶 There's no shortage of cliffs
around Ireland's coastline and there are some pet-friendly places
P.S. You can write us in Dutch/French too, if you prefer! :)
