I did a bit of Googling. There seems to be a plethora of those puppies.
Jacqueline Jones, Cabana Tammy, Richard Walton, Johnston M. Wright, Banach Wuzzy, Tina Marry, Jessica Fawton, and Ansley Dolan, each one a "consultant Gynecologist Surgeon and Oncologist Doctor," all have puppies available. Different breeds, mostly in the US, not Africa.
Someone baited the good Dr. Wuzzy. http://skunkfeathers57.blogspot.com/2008/07/ill-be-dawggoned.html
He wanted $350 for the puppy.
In 2007, a TV station played with a scammer who said he was a Peace Corps volunteer inCameroon.
At first he says shipping will cost $480 dollars, but drops it to $280 dollars. Over the course of a week of e-mails we talk him down to $200 dollars, then $150 dollars and finally $100 dollars to ship a dog from Africa to San Francisco. We send him nothing.
