puppy scam warning

For those of you selling puppies on the internet there is a scam going on. These people say they want to buy a puppy or even the whole litter. They tell you their agent in the US will send a cashier's check for the price of the puppy and the shipping cost to a foriegn country. When you receive the check they ask you to keep out your money for the puppy and wire the rest to the agent who will pick up the puppy. The cashier's check is counterfite. I received one of these checks but called the bank it was written on before trying to ca**** It was counterfit. The bank requested I send the check back to them. This check was for a large amount and I would have been out of the full amount had I cashed it. Thank goodness I had enough sense to check it out first. Linda
