Yorkies usually fit within the weight restrictions placed on pets. They're also usually less expensive to board than larger dogs.I enjoy travelling, I also travel by plane quite often. Yorkshire Terriers are indeed easy to travel with. Soon, I will write posts about Yorkies on a plane and how to get a passport for your dog (EU Pet Passport and US regulations). Now I will present you, as examples, the regulations for New York and London :-) New York, USA New York Times
Technically, any dog is allowed on public transportation in the city as long it is “enclosed in a container and carried in a manner which would not annoy other passengers.” If your dog is small enough to fit in a carrier that you can hold on your lap, you are all set. Cabs are likely to pick you up without a problem, too. (Nadia Zonis, the author of “City Walks With Dogs: New York,” responds to readers)London, UK Transport for London website
You can also travel with any other dog or domestic animal, unless there is a good reason for us to refuse it (such as if the animal seems dangerous or is likely to upset other customers). You must keep it under control on a lead or in a suitable container, and must not allow it on a seat. Staff can't take charge of any animal. You must carry animals on moving escalators or through automatic ticket gates.My dog is really calm while on a bus, I must only admit that some people think she is very sweet and she attracts too much attention, and this is the reason why travelling with her by car is better :-) While reading on the subject I also came across 10 Cities (in US) With Small Dog-friendly Transportation according to Animal Planet :-) click to learn more and check the text out!
