Hi Eleanor
Unfortunately, we didn't make it with the dog this year, due to the recession, we didn't buy the property we were looking at and, the dog got quite ill just after I had posted the question and she was unable to have the rabies injections needed for the pet passport. The latter is going ahead later this year, now she is stabilised and we will be out for long periods with her in 2010........fingers crossed.
The last time we were in PP, in May, we got talking to Mr. Barnard senior (Barnard Hamilton) at his office on the front and he has taken his dog back and forth several times. He gave us a number of tips about the ferries etc and I'm sure he would be only too pleased to talk to you on the subject.
