Pretty interesting to see an example of how some dog breeders think. It’s no wonder there are so many problems when some people might be breeding a male over 100 times before they realize he’s passing on a health defect. Includes a small photograph collection of color varieties and genetic defects. These have not aged terribly well when compared with digital photography, as many are washed out or blurry.
