First of all, strictly speaking, only dogs with official pedigree certificates are qualified to be called purebred, and then only on the basis of purebred are they divided into racing and pet classes. At the same time, there are two types of racing classes: those that are good enough to participate in competitions, and those that can take the championship CHAMPION class. In foreign countries, the concept of racing is the champion dog, but in China, all the Goldens that can participate in the competition are called racing Goldens. Also, a really good Champion Golden is hard to find, because even if both parents are Champions, there is only a 25% chance of having a Champion puppy.
