Ugg...
... while looking for a dog around this time last year, I saw an ad like that. Mentioned Africa and two yorkies. I called the number but never called back. It was too fishy and I suspected too good to be true from the get-go.
Though, we do get a lot of "Free Dog" ads around here because we live close to Fort Bragg. Soldiers get shipped a lot and need to rehome dogs. It's sad, really.
