There are many more scams around than there ever used to be. It’s partly due to the internet and how people can manipulate information to get what they want, namely the money in your pocket. A common scam is related to selling dogs, and is often targeted at buyers looking to purchase a Pomeranian puppy.
The dogs are real but aren’t the property of the scammers. Photos are stolen from top breeder's websites. Often the photos are photo shopped to make the puppy look very small, extra cute and appealing. Pictured left is a Pomeranian puppy bred by Dochlaggie kennels, Australia. Top photo is the original photo. Below is the exact same image after a few minutes work in photoshop. Lots of people love dogs and wish to purchase a cute puppy online, which is one reason why this scam works so well.
