We used Qatar Pet Relocators (528-6335) to process the paperwork to bring our dog over from the US in December and it was worth the cost. They took care of all the paperwork on this side and were very helpful in telling me what I needed to do onthe other side to make sure Ihad all the required documentation.

By the way the easiest and cheapest way to bring over a pet (assuming your airline allows it) is as accompanied baggage on your flight. The transport cost to bring our dog on the Qatar Air flight from NY was only $150. Air freight would have cost far more.
