Car Dog Carriers - Getting my hounds around

[Badgerboy]

Evening all,

Can anyone recommend a suitable dog booster seat/car carrier that could accommodate two miniature dachshunds?

Previously I used a small carrier, or our 6yo mini would ride shotgun up front on the passengers lap. Meg will soon be joined by a friend, so ideally I want to purchase something I can stash both of the hounds in, but also elevates them so they look around. (So an open topped carrier as opposed to a cage)

We typically use the other halfs car to ferry the dogs around, but very occasionally they ride in both of mine. Therefore I'd appreciate something that fits well, and isn't going to mark my interior! (All cars have ISOfix if that matters)

Thanks
