We used to have two BIG dogs - Pyrennean Mountain Dogs, each weighing over 50kg. Unfortunately we lost the male to stomach cancer. Both of them used to fit comfortably in the back of our cars, a Ford Galaxy and a Seat Alhambra. They are also great cars for diving with a huge load space. Both are diesels and return over 40mpg.
In terms of mobile and broadband, we are with BT who do a reasonable combined package. They used to be the only broadband supplier in our village and we've stayed with them.
