I just saw on the news this morning that you can go to
www.RipoffReport.com and the Better Business Bureau (search for the location of the breeder) to see if the seller is legitimate. There can be scams from dog sellers of all breeds on the web. I would first ask for feedback from other Yorkie Talkers if they had any experience with the breeder that you are interested in. The KATC news story was about
www.purebulldogpuppies.com . This is NOT a legitimate site. Another note: It is hard to proscecute online scammers because jurisdictional issues. Use a traceable source of payment such as paypal with a credit card. It was suggested that you do not use a moneygram.
