Realistically, there is nothing anyone can do about people lying. People lie. If you think a breeder is a liar, you don't deal with him. That's how we, as individuals, deal with someone we don't like or don't believe.

That being said, if a particular breeder is known to be a liar, but that breeder consistently produces quality dogs, then people are going to overlook the flaw in the person's integrity. In this game, a majority of people want quality dogs. They don't care so much about the lies. If Carver was alive today, can you imagine the dogs he would be selling if he were able to continue breeding the same quality of dog? People would question it, but they'd still spend their money with him. The dog game is full of people like that, and it has been for decades.
