That's awful -- hope your child is recovering.

I, too, had thought certain breeds of dogs were illegal to import to Qatar (rottweilers, all bull dog breeds, some others). That said, I know of a few people who DO have them. I have also heard that dog fighting is fast becoming a popular underground sport here.

If you haven't already, take pictures of your child's injuries. Document, document, document. Get copies of all medical paperwork dealing with the injury: descriptions of the injury, treatment, costs, etc. Detail any emotional/psychological trauma your child has undergone (nightmares, fear of all pets, etc.).

Next, (if you haven't already) I would go to the police to file a complaint/charge against the owner. Get a photo of the dog (if you can), and of the location where the attack occured. Any witnesses to the attack will probably need to be interviewd by the police -- have their names handy to give to them. The police should impound the dog until the matter is settled (unless the owner is a local and manages to sweet talk his way out of this...).

Then contact a lawyer. There are several around -- wrod of mouth is your best referral. A word of advice -- give them the name of the dog owner first and make sure they are not currently representing them for anything else (more of an issue if they are Qatari), to avoid a conflict of interest (I got burned on this issue a few years ago, but the lawyer didn't inform me/discover this until after about 6 months into my dealings with them -- a big waste of time and effort!).

I hope this helps! Best of luck!
