Usually when I take Lucas in the car, I put him in his carrier. Yesterday, it was nice and warm and for the drive to the petplanet store, I had his harness on, and attached his leash and wrapped the leash around the headrest of the passenger seat. There was enough slack for him to just look out the open window, and only enough slack for him to be in the passenger seat.
Is this ok? He seemed to really enjoy having his little nose out the window, I just want to make sure this is safe. Thanks for your input!
