Internet scammers are luring online puppy buyers with cute pictures and false promises, taking would-be dog owners for an emotional and financial ride.

Several organizations report an increasing number of complaints concerning online pet sales, including the American Kennel Club, the Council of Better Business Bureaus, the Humane Society of the United States and the Internet Crime Complaint Center, or IC3.

Over the past year, the Internet Crime Complaint Center has received nearly 700 complaints -- mostly coming from people contacted by fraudsters answering the victims' ads for pet sales or people who answered fraudsters' ads themselves. 

There are three main types of pet scams: an overpayment scheme, a Nigerian pet scam and a sale that provides you with an ill or dying puppy -- or no puppy at all.

Because the scammers frequently operate from overseas, it's often impossible for victims to recoup their money or take legal action. In the United States, California, Florida and Louisiana are hot spots. Victims lose anywhere from $250 to $2,000 to the scams, according to Alison Preszler, spokeswoman for the Council of Better Business Bureaus.

Here's how to recognize these scams and how you can protect yourself while shopping for a furry family member.

Overpayment pet scam (Scam to breeders)
How it works: This is a variation on a popular fraud scheme. An animal owner publishes an online ad offering a pet for sale. The fraudster contacts this person, negotiates a price and sends payment for the animal in the form of a cashier's check.

The trick is that the check is for an amount much larger than the agreed upon price of the pet. The scammer then asks the potential victim to return the overpayment, usually through wire transfer, back to the fraudster or a third party.

The victim eventually learns the cashier's check is counterfeit and loses the money he or she was supposed to get for the dog, plus any funds wired to the scammer. If the victim actually sent the dog, he or she won't get it back.

A number of the pet scams reported to the IC3 involved advance-fee or fraudulent check schemes, says April Wall, a research assistant with the National White Collar Crime Center.

Nigerian pet scam (Scam to puppy buyer)
How it works: Scammers either run online classified ads or create breeder Web sites offering purebred puppies -- typically English bulldogs or Yorkshire terriers -- either free or at a discounted price.

The story can vary as to why the animal is free or discounted -- the current owner is a missionary who needs to find the puppy a new home due to the terrible weather in its current location; the animal was rescued from a natural disaster and needs a good home, etc.

The scammer will then ask interested buyers to pay for the dog's shipment, down payment, inoculations and any number of other miscellaneous fees. The victims wire money for the dogs but generally only get excuses for the delay. Instead, they're repeatedly asked for more money to cover additional "fees" invented by the scammer.

Greedy scammers will concoct even more fees that the victim needs to pay after the dog has been supposedly shipped.

Unfortunately, once you wire the money, it's gone, says Preszler.

The bait and switch (Scam to puppy buyer)
How it works: Scammers are selling purebreds, "designer dogs," mutts and even made-up breeds through online classified ads and breeder Web sites. Often what people get are different dogs than the ones requested or puppies that are sickly. Sometimes they don't get anything.

Nearly 20 percent of the complaints received over the last year referred to Internet sales, says Stephanie Shain, the director of outreach for companion animals at The Humane Society of the United States.

People searching online for a dog they want find a Web site or ad offering puppies for sale and send e-mails or call the breeders requesting ones they want. Shain says it's common for the scammers to send you photos of the puppies they're shipping to you, but the pictures may not be the dogs you actually receive.

"Sending you a photograph doesn't mean they have that puppy," she says. "It's just a picture of a puppy."

Scammers count on people not wanting to send puppies back, even if they are different from the ones they ordered. Who is going to send a puppy back?

The animal you receive might be from a puppy mill, a factory-like place that produces large numbers of puppies in cramped, unsavory conditions for sheer profit. These puppies can come with severe health and behavioral problems.

And that's if you actually receive the dog.

April Buck of Grain Valley, Mo., was looking for an English bulldog puppy when she found a Web site offering one -- named Buck -- and wired $1,200 through Western Union to Miami to pay for the dog and its shipment.

The seller then asked her to pay another $300 for a DNA test that the airport supposedly required. She refused to send the money and contacted local authorities, the FBI and even Western Union about the scam with no luck.

"We didn't get our puppy but he kept our money," she says. "We lost a total of $1,289 to be exact. It cost us $89 to send the money."

Buck says the seller had a normal-looking Web site, claimed he had been in the business for 11 years and said the puppies were AKC-registered.

"I thought that meant these people were screened," Buck says. As it turns out, the AKC had never heard of the seller.

In any case, the AKC is just a registry, says Shain, not a quality control organization.

"If you don't know anything about the Web, don't buy anything off the Web," Buck says.
