Haha No I wasn;t suggesting that he SIT on a seat, or even Chrissa booked an extra seat for the room, I was just thinking if its busy then the dog would be a bit in the way (obviously the comfort of the dog is paramount though!) But then I suppose the timing of your journey could indicate how busy it would be...
Seem to remember you needed a dog ticket at one time but mine have gone free on train and Tube. Bus companies can charge for any dog. Others will let a dog you can carry travel free.
I always take my dog on trains and have done with previous dogs. I have never had any problems, and he's fairly big. People often make a fuss of him and bend down for a quick pat as they get on and off the train, and he gets loads of smiles. And you don't have to pay. I don't drive, so it's ideal for me.
Do NOT drive to London. It is very expensive to park there. As long as your dog does not make a mess on the train then it should be welcome. If you are coming from the midlands area then this company is best:
Nice one OG. I'm actually going to stay with my daughter in Surrey so I think I Will drive down from Northumberland. Got breakdown cover so shoud be ok and Toby can sleep the journey away in the back.
