We at the Source have been duped by scammers – and we don't want to you to be duped either. In the last few months, we have had several calls through 711 operators from people placing classified ads for teacup yorkies for adoption. These internet "adoption" ads are just a scam to get your money. They'll ask for a moderate sum to "adopt" their dog, say $80. Then they'll ask for another $100 for insurance, etc., etc. Needless to say, if you send them money through Western Union as they request, they will abscond with your funds and you will never see a yorkie, teacup or otherwise.
If you really want to adopt a puppy or a dog, please go through a reputable shelter – there are plenty of wonderful dogs that can be adopted that way.
