Dogs - apart from the 45-50 degree heat for 9 months of the year, if you can, leave them in Spain (or wherever you are coming from I would) with someone it would certainly be easier on them.
If you do decide to bring them over, do it in the winter months, its not uncommon for the ground handlers to leave dogs outside the aircraft whilst they sort the baggage and in this searing heat dogs like yours wouldn't last long!
Dog's aren't welcome here, you'll have to go out - away from anyone to walk them, often into the desert. They will spend their lives in air-conditioning and if you end up in Holiday Villas, your not allowed any pets anyway.
