I literally have one of these for both of my vehicles as well as one each for my parents and in laws.  My dog cannot see out the window and she was scratching our doors from trying to stand up to see. This eliminates her having to wreck our car as well as keep her safely confined.  Daphne cannot wait to jump into the booster seat.  When we forget to put it in I swear she just pouts. I highly recommend this to anyone with a small dog.
