OK so I do a lot of traveling (used to be year round but now it's just during the summer and school breaks)...so I'm looking for something like a dog "car seat". I've been looking around online and everything I find looks too small or too big for my front seat. I need something big enough for my Frenchie Maggie and my little Yorkie Scout. I can't use my backseat because I don't have a bench seat and my kids use the 2 individual back seats and I have to take my 3rd row seating out to fit all my luggage and stuff and I dont have enough room to fit Maggies HUGE kennel! Her kennel is actually for a dog much bigger than her..Anyway..does anyone have any experience with these? Are they worth the $$$ or would a seat belt harness with a doggie bed in the seat be just as good?
