How to avoid from being scammed?

Using either of they payment methods this person is asking for, you could be sending your money to BFE (or Cameroon) for all you know.

Or... better yet, just don't buy online. Get them from a good shelter, or a breeder whom openly welcomes you to their home and the area where the dogs are kept and raised. If you don't have any breeders near you for that particular breed you want. Try to find a rescue group. They will often have puppies, young and young adults and mixes and purebreds, and many of them are willing to place them far distances (around the country.)

I am a breeder and YES pay-pal is allowing people 45 days from date of sale to charge back the items. That person has the dog then gets the money back. Bad deal for the breeder. It has happened to me to. You will find breeders are getting charge backs, bad money orders, bad checks, and this is why they are all wanting something like Western Union, in which the breeder has to show a drivers license and they take all the info down before giving the money. Western Union has been around alot longet than pay-pal and is well known all over the world. Ask for a vet refrence, ask for others. trust your gut and talk to the breeder at length. But please dont use Pay-pal , they are screwing the bredders out of their dogs. and its not sick dogs they just go with what the credit card company says after the customer does a charge back.
