Dog guard (for Fiat 600)

I'm looking to get a dog guard for the car (a fiat seicento). At the moment we're attaching her to the seatbelt and on a harness but she's jumping all over when she's excited and it stresses me out.
Can anyone suggest a good dog guard for the car? I've only ever used crates in the car before, so I'm not sure what's the best one to get. I also look to order online and I'm wondering how to know if it's going to fit into the (rather tiny) car..
Grateful for any ideas!

Why not go into Halfords and see if this fits? I'm sure they'll open one up to see for you.

I have it in my Nissan Juke, which, although a bigger car, only has a small space that Kibo would be able to get through, so this was perfect and we only needed the main part, not the two extenders ( which you can see in the photo on the link )

In fact, this looks exactly the same and it says fits your car, and is cheaper too

we have 1 that goes in between the front 2 seats to stop them jumping through and its great

Try this sort that fits between the two front seats I have one although Bella is very good. http://www.argos.co.uk/static/Produc...er/1064454.htm

I bought a Solvit Deluxe Extra Large Booster Seat, it's really good, it just hangs off the headrest, it's really comfortable and washable ......though having seen Marco's dad I'm not sure how long he will fit in it

that front seat one looks good, as if I have the back let down to put them in there is a gap between the seats, Cariad and Lona are very very good and don't even think about it, the other 2 I put a harness on, but that front seat thing would solve that.

They are really good. Had mine years and leave it in situ

Thanks for all your suggestions, I'll have a look into it!
I definitely want something for the boot and not just between the front seats. Ella can sometimes screech when she gets really excited (for example if she sees a field) and it really hurts my ears. I'd rather she's a bit further back. At the moment she also loves jumping up on the boot shelf thingy and sitting there, it makes me nervous the way she hops around and tries to stick her nose out the front window..
Better be safe than sorry!
