I sent off enquiries to various car companies, asking whether they allowed animals in their rental cars. Unfortunately, I only received answers from 2 companies...
Tel: 00357 25 880222
Response: Yes you may rent a car with us. Please be aware that should the vehicle be returned dirty or stained (as a result from your pet) a valeting charge will apply.
I apreciated the swift response, and the polite, clear instructions. I would definitely recommend you try this company
Response: I can confirm none of our supplier we work with allow animals in their rental vehicles.
Apologies for the inconvenience this may cause.
Again, I appreciated that they replied, and that they had set rules concerning dog travel, even though they do not allow dogs.
I will update this post as and when I get further information...........
