I live in the UK and really want to travel to America with my dog, Honey. If you plan on coming here you will need to get certain vaccinations at least six months before you come. Also right now I cannot find any airlines which will let anyone take their pup in the cabin with them, only as checked luggage. However, depending on your financial status there is other ways e.g. travelling by boat (not for me) or airlines which specify in flying dogs(no idea how much this might knock you).
Try out these websites and search the web and see what you find:
Taking your pets abroad : Directgov - Travel and transport Pet Exports Ltd. UK. Taking your pet abroad. Frequently asked questions.
Hope you get it all sorted and can bring your pup with you!
