I have a Miniature Poodle about 15 pounds and she absolutely loves to ride in what I call her "Buggy". I thought that she would be afraid of it but she is not afraid at all. She is rather tall when she sits but there is plenty of head room for her. There is plenty of room width wise and the mesh sides and front give her loads of air and view. The "Buggy" is sturdy, made well and has a security ring to attach a leash or collar. I recommend this product.
