I have a small Snoozer and a large snoozer. The large is well....laaaarge. lol. My girls are 7.6 lbs and 2.6 lbs and there's room for probably two more yorkies in that thing.
The small goes up front in the passenger seat when I take 1 of them instead of both. I kinda wish I had two smalls instead of one large. They get their legs tangled up in the seat belt safety loop.
I highly recommend looking around
