A good few years ago several of us went Holyhead to Dublin(can't spell Dun L??) by foot with a Boxer, a BC a Beardie and a BSD. The ferry we used had airline type crates on the car deck. The dogs were fine and as far as I remember we were allowed to go and check them also stay with them until sailing and go down before car engines were started.
These were dogs used to going to shows etc but people do bring pups in and send them abroad and don't suppose this is really much different
