I came across this pet requirements page, but it is unhelpful in sharing information as to how to get an International Health Certificate overseas (specifically, in Ghana - would I have to find a vet willing to go overseas from the U.S.?) And finding a place to keep the dog(s) confined for the 30 days upon arrival in the U.S.
If I do adopt, it won't be anytime too immediately, but I miss these dogs. I'm not even sure that the family who owns them will be up for letting go of them, but as is to be expected, animals are not treated very well over there, and they don't seem to actually care about the dogs.

It was unusual to them that I liked the dogs so much. The dogs don't get to meet many people that are loving towards them, and it makes me miss them all the more to think of how they took to me.
