Many people write to us asking if they can travel with pets on a coach, describing their favorites as a tiny, trouble-free, not requiring a lot of space. The answer is simple and definite - NO you can not.
Unfortunately, you can not travel with an animal on the coach. None of the British or European licensed coach operators will allow you to travel with a dog or cat. The exceptions are guide dogs.
So really it does not depend on the size, behavior or wage of the pet. Long journey by coach make the animals feel unwell, which may have an impact on the entire journey.
