Thank you all for your responses. We have been to the boat a few times over the last few days and nothing has changed. He is as bad as he first was. We tried to ignore him and carry on as usual but allhe did was pant, shake and constantly move about the boat. We bought him a thundershirt which we read reviews about, it's supposed to help with thunder storms, bonfire night etc and supposed to help with noise , General anxiety and travelling but it made absolutely no difference at all. I am at my wits end with it all. I haven't enjoyed one day on board so far and have been looking forward to boating for so long! I don't know what to do for the best, I got ratty with him today which is the last thing I wanted, I just want him to be happy!
