There is nothing quite as dog-friendly as a Volvo Estate for transporting Basenjis ! Mine have always ridden to shows in them - two large crates can accommodate 6 Basenjis in comfort.
I am on my 5th, I think - could be my 6th. The last one did 216,000 miles. That was the square tank-like version. The current 10 year old V70 is overall broader, but without so much space inside, which means a single crate is all it will take. But it is enough for my age-depleted pack.
