I would make a police report so its documented and try to find out if the dog has done this before. I am sure you could sue but the lawyers here cost a fortune, Qatar gives compensation in a very strange way its like a percentage of what you lost, say you damaged a body part its like 15% of something! I hope the child is getting better dog bites are very dangerous my brother once got in between his own dog and another and was bitten badly and he had to take serious antibiotics their saliva can really make for infection so use betadine and seek good medical care for the wound. I hope now the dog is adequately secures. Rottweilers are banned here but they do nothing if its already here. The last Vet Dr. Penti was raising lots of dogs like that and selling them.
