Hi,
I just moved to Accra with my dog from the Netherlands. We had a direct flight so I don`t know which paperwork you will have for your stop-over, however, for entering Ghana with pets its good to get in contact to the "Pets Place" in Accra, you can easily find the contact via the internet.
Also have a look at some earlier postings here, they were helpful for me:

We arrived just some days ago and everything is fine. The only challenge for our dog is now that she is just staying on the compound as we are afraid to go for a walk due to the wild dogs running around. Also she realy miss to play with other dogs, but I strongly hope she will be fine soon.
I wish you all the best, good luck!
