My family includes three small dogs, approximately 7, 11, and 20 lbs, all rescues. My biggest boy is a havanese who could not even travel a mile in the car without acute carsickness. The guy who does my hair, also a havanese dad, recommended the Snoozer. In fact, he had one to show me, since his dog comes to work with him. After poring over the reviews I bought one of the bigger Snoozers, and, like magic, Marvin's carsickness was instantly cured. Now the three of them are constantly fighting over the Snoozer, trying to trick the others away from the throne, and my smallest pup gets squeezed out, so I bought her a Snoozer console seat, perfect size for her. Mostly we use the seats in the house, but they travel with us too. Only negative: washing the cover is painful -- especially putting it back on.
