I noticed while trying to trace some pretty famous bulldogs that bloodlines are being diluted by continuously crossing.
Yes this is true and i totally agree, and i think the cause of this is because some breeders are not well educated on line breeding and inbreeding to preserve the genes and blood, but they are more focused on breeding to any "ch" or well proven dog, and in some case's just because they feel there dog is missing something


I understand why crosses are done but I would think you would want to have some inbreeding in order to keep a inventory of the original blood on your yard for future use not to mention pure preservation of blood.
Line breeding is second to inbreeding to keeping any blood preserved, which i think is the best way to keep our dogs the same as they were years back. Inbreeding will do nothing but tighten up the blood, and preserve its traits and characteristics of a specific blood or strain.
