MamaBas is right in that most, of not all, rental companies will not allow dogs in their cars. Vans are a different matter, they're usually 'working' vans and they don't mind what you do with them. Unfortunately though they often have solid bulkheads, so you can't see the back of the van or the dogs. Go round your nearest rental companies and look at the vehicles, recommendations are pretty worthless unless they are from people in your area. Be honest with the rental people or you risk losing your deposit or extra cleaning charges. I've hired several vans when I have doggy friends staying and too many dogs for my car, last year I hired a minibus that we fitted 9 people and 13 dogs in with the companies blessing.
