What to do if you don't get a coupe/cabin to travel with your dog?

If you have not been allocated a coupe/cabin, you can do the following:

Get to the station early and have your dog booked on the train
Request fellow passengers to exchange seats so that you and your dogs can get a full coupe/cabin.
If your dog is comfortable with strangers and your fellow passengers are okay travelling with your dog, get their approval in writing and share it with the ticket collector when he comes around. Once you get it writing, share it with the TT - most chances are that he should be OK with it. In worst case scenario, you may be asked to pay a fine for your dog, which is equivalent to 6 times the cost of your dog's train ticket/receipt, mentioned above.
