A purebred dog is a dog that has certain genetic distinctions due to a careful breeding plan. Purebreds do not maintain their distinctive characteristics unless the careful selective breeding continues in the line. That is why you see so many purebreds that are quite different than the breed standard when they are produced through indiscriminate breeding. Ears flop, bites change, personality characteristics become troublesome, and health issues abound due to indiscriminate breeding. In order to maintain the quality of any purebred certain scientific breeding standards have to be met. It is truly a science. It does not happen by chance.
While many larger Yorkies are seemingly healthy they can be just as subject to problems as the tiny ones if they have mishmash breeding behind them. Many of the so called teacups come from litters that also produced over sized pups. The genetic pool is so large in this type of breeding that it is like a giant roulette wheel of possibilites. A breeder with extensive knowledge of the genetics of their breed and who does extensive testing of their breeding stock is helping to eliminate the bad possibilities. That is one of the many reasons why those who have taken the time to study the subject try to warn people not to buy from the hobby, BYB, and puppy mill breeders.
A dog owner can call their dog a "microscopic" Yorkie if that makes them happy but the disdain for the tiny terms used to enrich bad breeders is about the exploitation of the dogs and not merely about someones terminology preference. |
