And I will of course make sure that the dog is fully vaccinated and have all it's documents in order - and that goes for every country we will transit.
Also, I would have my stepfather come and pick me up in Saudi, as women are not allowed to drive there.
When I was last in Doha, I was told that bringing a Great Dane was illegal and impossible, but now I see that they are only restricted, so I guess I have all my questions answered.

Luckily my family lives in a big house with a nice garden with the lagoona in the backyard, so apart from the heat, the dog wouldn't get it any better. :)
