It is easy to ship the dogs yourself as extra baggage on your return flight. You need the Pet Passport and paperwork from your vet. Take that to Cargo Village - Dubai Vet who checks your dogs chip and paperwork and produces the export paperwork.
The trick is to make sure Ek knows you are bringing the dogs. Call them in advance (at least 7 days). Drop them off as you check in (go a bit earlier than normal).
