If you plan to have your dogs ride in the back, by folding down the third row seats, it should work quite well. There is a very deep trunk area in back of the third row, but the X comes with a "board" to cover this deep well, which you simply lift up and then fold down to cover this well. This then combines with the folded flat third row to provide a large flat area for the dogs. Even two large dogs whole be able to lie comfortably there. They would be fairly walled off from the passengers by the wall created by the second row seats.
There is a small space between the second row and the folded down third row where a dog paw could get stuck (I remember around 3 inches), but this could easily be blocked off for their safety. The other problem that I foresee is the glossy plastics backs of the second row seats. I know that ours will be quickly scratched up by our dogs -- I really wish that they had made the seat backs either matte or metal finish.
Of course, if your dogs are as spoiled as ours, they will really enjoy sitting in the second row with their own heated, ventilated seats
