After reading numerous reviews I knew I wanted to purchase this booster seat, but I wasn’t sure which size would be best. One reviewer stated that the small was too small for her 10 lb. dog. I find that to not be true. Because I wasn’t sure which one to order, I ordered both and ended up returning the large one. I have a 10 lb. Havanees and there is plenty of room for him. The large booster seat is the same height, but is wider so that maybe two small/medium size dogs could sit side by side. I find the booster seat to be well made and do a great job at not only keeping my dog in place, but I find he is also calmer. Maybe because he can see outside, maybe because he feels more secure (than sliding around on my leather seats). Whatever the case, he is happier and I am not so worried about him getting injured if we are in an accident or if I need to hit my breaks quickly. Oh yeah, there are two leads in both the small and large booster seats, so either one of them can officially secure two dogs!

My 6.5 year old Dachshund had never been in a care seat before and loves this! It is so soft and comfortable and he goes to sleep riding down the road in it. Wish I had bought sooner as he was thrown in the floor a few times due to slamming on the brakes and now he is safe.
