We came across something on Fb recently. A buyer had bought a Rottie pup and came in to one of our groups on FB. Naturally we were all excited to see a new puppy, who was gorgeous, someone asked what the breeding was, the pedigree was photographed and shown - the "breeder" had used the name of two stud dogs who had previously died. Had used the stud book numbers etc. etc. and to anyone unsuspecting, it all looked genuine. The breeder made all the right noises into contracts, returning the dog for any reason etc. so the buyer had been well and truly duped. The pedigree was false. When it was spotted, funnily enough, the breeder couldn't be traced.... So, check pedigrees thoroughly and ask questions. This "breeder" has been doing this for years and years apparently. Grrrrr.
