Hi Daniel, welcome to the forum. My condolences for the passing of your Samantha.
You have definitely come to the right place to get help locating a rescue or pup. Basenji Rescue and Transport has quite a few rescues in Michigan. I don't know if that is within the distance you're willing to travel (or how close you live to the border)

If you are looking for a puppy I know of a litter due end of December in Ontario (Niagara Falls area) and the breeders are also members of this forum Here's the page:

Wherever you end up getting your new addition, make sure to do ample homework on Fanconi.
