A friend of mine has 3 shih-tzus and two of these car seats. They are very nice. I strapped Ginger in once and she really seemed to like it. She was on top of the world. She looked really cute in it, too. AWWWWWW.
However, with two teapots who like there own space, I couldn't justify buying two of these....so a couple of laundry baskets, inexpensive bed pillows & cases later, and straps from the pet store (to attach to their harnesses) and we have two matching car seats... that are completely washable. Of course, people think I'm traveling around with my laundry. But my furbutts are comfy and safe in the car and I spent about $15.
That being said, I think you'd like the lookout seat. They seemed really nice to me. Make sure you take pics if you get it!
