The seat itself is great, the clip to clip onto a harness or collar is TERRIBLE. It got caught on my dog's back leg and wouldn't come undone. It is not a normal leash clip the slides down to clip onto the ring, you have to push in to release. I had to pull my car over on the highway and the only way I was able to free my dog was to push the clip further into his tendon to get it off. It was an awful experience, do not use the clip.
