CzW are different. Or better said their breeders are different. Just look on the litters - most breeders do not repeat the same matings. Why? Because if the puppies from the first litter were nice it means they will be used for breeding in the future. And if the puppies are of low quality or have health problems it make no sence to repeat such mating.

Well, here in Italy we have at last one breeder (but he is the biggest one, more then 100 puppies/year) that behave like in your first paragraph. . Have a look in the database. Heavy inbreed 'cause "they are nice". Cutt has been used for more then 100 puppies and now Miky is going the same way.
