Using the EuroTunnel

Hi, I am planning on taking our first trip with the caravan to France in the near future.  I have many years of experience driving abroad solo all over Europe so that is not a major concern.  I would appreciate some advice/info on how they load caravans on to the shuttles?  We intend to use the shuttle as we have two dogs with us and do not want to have to leave them.  Many thanks.
