Just purchased my second Variocage. First one was a Single Large (2016) and the new one is a Double Large. LOVE LOVE them! Matching car year, model to the recommended Variocage sizes works like a charm. Since we’re on the road for dog competitions, I’m know they are in the safest, crash tested crate possible. I would trust my Australian Shepherd in none other. The double brought us good luck at our last competition.
