Immigration procedures for dogs? (Kigali)

Hi all,
after a short trip to Rw a couple of weeks ago I am now planning a "proper" trip to visit Rw and do some hikes. Travelling from Dar with my own 4x4, I'd like to bring my dog, which loves hiking as well...;-)
Any idea which immigration procedures, requirements etc.will apply for a Tz dog travelling to Rw??? She already fulfills the EU immigration requirements - but I am sure, there might be some more for Rw.....
Tx - and best wishes from Dar,
Susanne
