Don't forget anyone can show, this doesn't mean much. Most show breeders don't call themselves show breeders and, in fact, it seems like hate that term, I think they use words like "Exhibitor Breeder". You could have a puppy mill and call yourself a show breeder, it could just mean you just showed one dog once, and it lost.
If this person really is a YTCA member, bragging about 'breed some bitches who are out of standard' would probably be frowned upon. However, it shouldn't be forgotten, that breeders are breeding TO standard, in other words, they are trying to produce pups that will meet standard, and that's why some breeders use breeding dogs that themselves may not be standard, the GOAL is always the important thing. For example, an 8 pound dog is not standard, but she may produce dogs well within standard, a black dog while not specifically standard, may be needed to keep the blue from being diluted too much and correct the a lighter blue mate. Ten litters a year seems excessive to me, and they probably are selling to fill the pet market and NOT to improve the breed. If a breeder uses marketing terms, such as "show breeder" or "champions in bloodline" to me, they are just puppy salesman, and yes, the YTCA has breeders who breed for the wrong reasons. People need to be very careful when researching a breeder, and belonging to a club, means you had to only fool a couple of people, but the YTCA does have some checks and balances in place to eliminate poor breeders. Some people want to join the YTCA, not because they believe in their values, but because they think it will give them prestige, and they will sell more puppies.
