I got this for my son's two small dogs. They all love it. There is plenty of room for them and it sits up high enough for them to look out the car windows. One likes to lay down and sleep, but the other was always jumping up and running around to look out the window. The Car seat keeps her up high enough so she can look out; even for a small dog. There's still plenty of room for the other dog to lay down and sleep. The car seat attaches easily to the seatbelt and it comes with two little seatbelts to strap the dogs in safely. It works great and keeps them safe. It's sort of big though, and takes up half the back seat, but it's worth it. It keeps them happy and safe for long rides and short trips to the park.
