Chollen understand. There is a breeder Mr Smith who owns 2 KCI registered Great Dane pairs. At one show, one of these dogs becomes a champion. Next month, Mr Smith let these pairs mate. The puppies from this pair will also be registered. On a certificate, the puppies pedigree record show one of the parents is a champion, ie a prefix CH attached before the name of Sire of Dam.
The value of these puppies ( belonging to champion line ) will be higher than average puppies ( not belonging to champion line). Therefore, while a Great Dane puppy belonging to a non-champion line will be sold at Rs 15k, Mr Smith's Puppies whose father or mother was the best dog in a show will be sold between 20-30 K.
That's one of the ways of earning more money. Breeders madly take their dogs to dog shows expecting their dogs to win the shows so that the puppies produced from them fetch more money for them.
