Our 6 year old bedlington cross gets very stressed in a car. We’ve tried numerous beds, mattresses and calming sprays with no effect, he whines, barks, shakes and pants, so we avoid taking him in the car. We thought we’d try this car seat/bed as we had an upcoming 5 hour journey. What a revelation! He curled up and was quite settled. Even though it is secured with a strap at the back, we also hooked a bungee strap from the front of the bed and around the headrest in front to make the front more secure. The bed is waterproof with a comfortable cushion, handy pockets for treats and toys. I would highly recommend.
