Hi,
We have a vauxhall Zaf. XCLSV 16V (7 seats)It has plenty of room for the dogs you can put the back seats down also the second row back, an even bigger car is the Citroen Grand C4 Pic.1.8SX.(Large7seater) You can put the seats down also.
We had this on loan, it is enormous inside, we had it while our 2 week old car!! was in for repair, as a white van driver ran in to it while parked and damaged all the front.
We spent a lot of time looking for a car with large boot space, The Vauxhall was the best in the price range.
