I have had dogs here - and brought them from abroad like you will. First of all, choose your airline carefully. I recommend KLM because they really look after your animals.

Secondly, the paperwork - you can do it yourself but it's a lot easier and a whole lot less stressful using a pet relocator - I used Qatar Pet Relocators (they have a website) and was very pleased with them - there are others as well which I believe are also reliable.

I take my dog out very early in the mornings for his main exercise of the day - especially when the weather is hot to avoid the 50C+ temperatures. I also take cold bottles of water and a dish with me and give him regular drinks so that he can keep cooler. He goes for shorter walks later in the day and after the sun goes down as well.

Once the weather breaks (come October or so) it is much easier on the animals and you can venture out . My dog is also a house dog, he stays inside on the cool tiles with the AC going - if you live in a villa you can install a dog door so that the dog can get outside if need be while you are at work.

Hope that helps.
