I put it on my front car and for now it has not to be used, believed my dog will love it.
The first time we used was a 4 hour drive. Within the first hour, my pup was sleeping peacefully, cuddled up in the carseat. We were so surprised to see her so comfy! I'd recommend this carseat to anyone!
I bought it for my Frenchie. It has a soft blanket inside and is the perfect size.. Definitely recommended for small to medium sized pups!
