Transporting dogs…

My dearest OHL, with quaint attachments, are going to get a dog. They have already locked one in the shelter in their heart. It is a beagle or beagel, no matter. And now the question…. How do you transport the Kö…. ohm dogs into your moose? On the back seat, in the trunk, in an extra box etc.? I don’t want to let my good leather seats ruin… Greeting Heiko
